BACKGROUND ~F THE INVENTION:
The present invention has made reference to
the following information of the published and granted
patents:
U.S. Patent Nos. 113,656; 4,240,621; 171,868
French Patent No. 471,674
Austrian Patent No. 174,872
1. Analysis of U.S. Patent No. 113,656:
; A. Structural character is that:
a transverse back arc clamping cl`aw is
placed from ~he front side to couple with
the jaw which possesses an arc slot;
an arc slot of a clamping sheet at two
sides is coupled with a pin at two sides
of the jaw in order to prevent the work
piece from falling down;
the work angle can be adjusted upward and
downward with no special limitations.
B. Function: It is used to clamp
l¢ngitudinal non-parallel work pieces.
C. Deect o the structure is that~
the method of placing a work piece from
the front side must assemble clamping
sheets h and h' and the pins at two sides;
~5 therefore, it needs many parts, and
easily loosens and increases the
ineffective space, the fragile parts are
exposed outside to be collided and out of
work; there is no design for limiting
the upward facing angle, and when the
clamp length of the clamping piece is
shorter than radius H, it cannot tightly
clamp the work pieces as shown in Figs.
A-l, A-2.
2. Analysis of U.S. Pa~ent No. 4,240,621:
A. The structural character is that:
it possesses a movable clamping claw 28
"~
and fixed jaw 26, both of them are
oppositeand possess a spherical concave
socket and contain a steel ball 36 in
the middle;
due to the pulling join of springs 45, 46,
it can make a universal slide to clamp the
work piece.
B. Function: It is used to clamp a longi-
tudinal or transverse non-parallel work
piece.
C. Defect of the structure is that:
it only submits the design of the single
set clamp, therefore it cannot pay
attention to the auxilliary structure of
sliding work piece away when the
inclination angle is too long; there is
no design of the mul~i-angular clamp
for irregular-shaped work pieces.
3, Analysis of U~S. Patent No. 171,868:
A. Structural character is that:
it possesses a two-sectional fixed jaw,
wherein its one section near the clamp
surface can make angular slides;
one section near the clamp surface
possesses an arc slot which joins with
a pin on the fixed section, and between
said two sections, there is an arc
coupling surface.
B~ Function: It is used to clamp transverse
non-parallel work pieces.
C. Defect of the structure is that:
the two sectional structure can make the
body of the vise become longer;
two jaws the motion bodies which will
affect the stability of itself after
clamping.
4. Analysis of French Patent No. 471,674:
-- 3 --
A~ Structural character is that:
it possesses a multi-set of a swing-
type Y shaped arm;
each branch joint possesses a movable pin.
B. Function: it is used to clamp irreg?llar-
shaped work pieces.
C. Defect of the structure is that:
the terminal clamping claw does not
poss~ss any dir~ct rigid support surface,
and its clamping strength is lower;
its structure i5 complicated;
the positions of four sets of support
psints 11 are constant, and its
application for clamping irregular-
shaped work pieces is limited.
5. Analysis of Austrian Patent No. 174,872:
A. Structural character is that:
it possesses four sets oE movable clamping
claws 5 which join with arc movable jaw 4
by pin 6i
the distance between the clamping surface
of movable clamping claw 5 and pin t is
larger than radius of circular arc surface
which is joined by blocks 5 and 4;
arc-type mo~a~le jaw 4 possesses an
inclined surface which couples with fixed
jaw 2 and motion jaw 2' and has no
limitation structure and can be taken
down freely;
as shown in Fig. 2, joint arc surfaces of
movable clamping jaws 5 and 4 do not
directly contact each other (as shown in
the drawing by double dotted lines),
B. Function: It is used to clamp
irregular-shaped work pieces.
C. Defect of the structure is that:
the distance between the clamping
4 -
surface of clamping claw 5 and pin 6 i5
larger tha~ the radius of the circular
arc, and ~he range which is suitable for
work pieces i5 limited (as shown in
S Figs. B~l, B-2, B-3, B-4);
arc-type movable jaw 4 has not been fixed
yet, and will fall down from the front
side (as shown in Fig. C-l);
it possesses plural safety points (as
shown in Figs. D-l, D-2, D-3~ which will
cause the balance of the working table
unstable and make troubles when milling
processing is mass-produced (as shown in
Figs. D-4, D-4-1 r D-~ ~ D-5~1 ); movable
- 15 clamping claws 5 and 4 are joined by
pin 6, and the circular arc surface does
not rigidly couple with claw 4, and
therefore the clamping force is limited.
Therefore, the present invention is a
structure of vise which is designed to
overcome or at least minimize the above
defects. It is characterized in that:
at least one of the two sets of
corresponding clamp jaws possesses a
stably ~ransverse directrix; the stably
~ransverse directrix includes a line
which is constituted by the line of claw
surface of plate-type clamping used for
fixing posi~ion; or at least two sets
of movable clamp jaws which have a
metacentre respectively.
Therefore, the present invention can solve
the problems and defects of each of the
above cited references and keep the
original merits while possessing further
merits. Summing up the above character-
istics, its combination includes the
.
,. .
.~ ~
following types: it is constituted by
two sets of corresponding clamp jaws
which respectively possess two sets of
movable jaws; it constitutes two sets of
corresponding clamp jaws wherein one set
can swing or move to face upward; two
- parts of the clamping structure are
constituted by two sets of jaws which
possessthe plate-type clamping claw,
wherein one set can swing or move to face
upward; it is constituted by two sets of
corresponding clamp jaws wherein one set
possesses the plate-type clamping claw
and the other set possesses two sets of
the movable clamping claw; it is
constituted by two sets of corresponding
clamp jaws in which one set possesses the
plate-type clamping claw and the other
set possesses two sets of the movable
clamping claw, wherein one jaw can swing
or move to face upward; it also possesses
other similar functional combinations.

DETAILED DESCRIPTION OF THE INVENTION
_
The vise of Figure 1 has the following
features:
1 The inner concave dovetail arc slot is
~5 installed on the back side of the half-circular
clamping jaw and a limiting pin rod is installed at two
ends of the said dovetail arc slot. Moreover:
a) Screws are coupled with the dovetail arc
slot, and
b) Screws and dovetail block penetrating
through the back side of the jaw are installed on the
back arc of the jaw.
2 There is no support seat on the bottom
side of the moving jaw; thus the movable clamping jaw
can directly slide on the guide track of the machine
seat to increase the suitability for clamping the
working piece.
3 The height of the bottom side of the
movable clamping jaw of the fixing jaw is the same as
that of the sliding track on the machine seat.
4 The inner concave arc face between two
arc ~lots on the jaw concave arc face between two arc
slots on the jaw e~tend downwards through the bottom
of penetrating the working piece.
5 The outer side of the jaw contracts
towards the inside, thus the sliding motion of the
clamping jaw cannot be stopped, when it clamps the
~7
~2G~ i,.'3
~ 39 -
working piece with the concave shape on the middle
section.
As shown in Fig. 1, four sets o sliding
clamping claws 1001 are respectively assembled on the
fixed jaw 1101 and motion jaw 1201, at the center of
arc-shaped socket 1301 of jaws 1101 and 1201, and there
is a h~le 1401 to accommodate small ~ylinder 1501 at
the bottom of clamping claw 1001 or rotation and sliding.
One guide rod 1601 penetrates through support arm 1801
which has screw inner hole 1701 in order to drive
motion jaw 1201. ~ne end of tool seat 1901 has support
arm 1801, its other end has the fixed jaw 1101, and
its middle section has guide rail ~001 for motion jaw
1201 to make reciprocating driv~. For joining motion
jaw 1201 and guide rail 2001 at the bottom of motion
jaw 1201, a cylindrical structure 2101 or bilateral
parallel column-type structure 2201 couples with guide
rail 2001, and at its bottom, there also is a fixed
sheet 2301 which is screwed by fixed screw 2401 in the
screw hole 2601 at ~he bottom of coupling column 2101
or 2201 of the motion jaw. The motion jaw is placed at
the lower side of coupling hole 2801 of the guide rod,
and there is a screw hole 2701 for screwing the setting
screw 2501 of the guide rod.
Fig. 2 is a perspective graphic view of
clamping claw 1001 as shcwnin Fig. 1. Its front side
is a plane, and two sides are reversed triangular and
therefore, it forms a three-side clamping surface.
Its m~rit is precision and its suitability for various
shapes of the clamped pieces;
Fig. 2-1 shows the clamping claw 1002 as
shown in Fig~ 2 in which the front side of the clamping
claw 1002 then possesses the concave arc type in order
to enchance the adaptation of the clamping claw to
clamp irregular-shaped work pieces;
Fig. 2-2 shows the clamping claw 1003 or
1003' in which its sliding surface is o a multi-
. ? ~,1
- 4~ -
angular continuous arc shape or multi-plane shape and
is used for coupling with the arc shape socket in order
to reduce the frictional rssistance;
Fig. 2-3 shows the clamping claw 1004 as
shown in Fiy. 2 wherein for the clamp surfaces at two
sides of the clamping claw, one is in a concave arc
shape, the other one is in a t~othed type;
Fig. 2-4 shows the clamping claw 1005 as
shown in Fig. 2, wherein the clamp surface of its one
side is concave arc ~hapP;
FigO 2-5 shows the clamping claw 1006 which
is a semi-circular clamping claw and the side nPar
another clamping claw of some jaw poss~sses a cutting
angular clamp surface;
Figs. 2-6 and 2-7 show the semi circular
clamping claw 1007 which is processed by bending the
metallic plate to be used for reducing cost;
Fig.s.2-8 and 2-9 show the clamping claw 1008
which is processed by bending a metallic plate and has
a round hole in the middle and possesses a three-sided
clamp surface for reducing cost;
Figs. 2-10 and 2-11 show the clamping claw
1009 which has a special curve-typa clamp surface for
clamping and fixing special shaped work pieces.
Figs. 2-12 and 2-13 show the clamping claw
which possesses the clamping claw structure 1010 at the
sides to lock and fix different materials and clamp
diferent soft and hard pieces;
Figs. 2-14, 2-15 and 2-16 show the
embodiment of themaln body of clamping claw lOll and
clamping claw sets, 1012, 1013 and $ixed screw 1014 of
the clamping claw, wherein the front side o$ the
clamping claw possesses a claw shape and changeable
dif$erent materials. Besides the above various designs
which can extend the applicatory range, the structure
of clamping claw 1015 as shown in Fig. 2-17 can further
be in a similar cylindrical shape and possesses at
least a section of a circular arc to couple with the
socket, and along its circumference, there are
structures of toothed shape, convex arc shape, or
- concave arc shape, and its bottom possesses a central
hole.
Fig. 2-18 shows the clamping claw 1016 as
shown in Fig. 2-17 which is of similar cylindrical
shape and its bottom and upper parts possess a small
projected column for coupling.
~ Fig. 2-19 shows a clamping claw set 1017
which is made up of a laminate of several juxtaposed
clamping elements each of which possesses concave and
convex circular arc and toothed surfaces and plane;
and in the middle, there is a round hole for rotating
and adjusting to be suitable for various work pieces,
and it is characterized in that the largest distance
of each type of the clamping surfaces is constantly
smaller than the radius of the back arc of the socket
in order to rotate and not to interfere with the
socket.
Fig. 2-20 shows a clamping claw which is
constituted by joining clamping claw set 1017 and
circular axial column 1019 with grooves or arc gaps.
Due to stable laminate 1018 this type of clamping
claws can reduce transformation or destruction which
is caused by the weakness of strength and rigidity of
circular axial column 1019.
Fig. 2-21 shows the universal rotatable
multi-faced clamping claw 1020 wherein on the inside
it possesses spherical axial column 1021, and on the
outside it has ring-shaped fixed plug 1022 which
penetrates thxough round hole 1025 and is locked by
screw 1023 in screw hole 1026~
Fig~ 2-22 shows the spherical axial column
of clampiny claw 1027 which is projected upward in the
middle part for coupling on the fixed jaw or motion
jaw of the tool seat.
!:..
- 42 -
Fig. 2-23 shows the movable clampiny claw
1028 in which its middle part possesses the couple-
side concentric circulax arc structure and makes free
- universal rotations by a concave central axial column,
wherein its two ends are coupled and placed on the jaw
and it is placed on the cover.
Fig. 2-24 shows a movahle clamping claw
having a two-sectional universal clamping claw
structure which includes movable clamping claw 1032 and
rotary and adjustable auxiliary jaw 1029. The joining
place of two sections of clamping claw is an inclined
conic surface, wherein at one side there is screw hole
1031 which is vertical to the inclined conic surface .
At another side there is threaded bottom 1033 for
screwing in the screw hole in order to rotate and
adjust, owing to the axial line of the threads being
vertical to the inclined conic surface. ~herefore, in
rotation and adjus~ment, the axial line between two
sections o~ the clamping claw will be varied in ~he
angle of elevation, and the rotary adjustable
auxiliary jaw and fixed jaw or motion jaw are joined by
screwing threaded bolt 1030 into the bolt for rotating
and adjusting the circumferential angle of the two-
sectional clamping claw set or further rotating
- 25 continuously to adjust the stretched distance of the
clamping claw set, and due to the two kinds of
angular adjustments, clamping claw 1032 can make
universal adjustments.
Fig. ~-25 shows a two-sectional universal
clamping claw structure having a bearing set and is
set by a ring-shaped groove, and as shown in the
drawing one set of movable clamping claws 1037 or
rotary auxiliary jaw 1034 possesses a hole-type
struc~ure 1040, and its side has a small screw hole
35 1035 for screwing the setting screw 1035', while
another set possesses a circular projected column 1038.
On the projected column la38, there is ring-shaped
,, ~
- 43 -
groove 1039 which is limited by the above-mentioned
setting screw 1035' in order to prevent its falling
down and will not interfere with its rotation. The
joining surface of both of them possess a pan-shaped
bearing 1036 to enhance the precision of the adjust-
ments of the clamping claw. The method of joining of
rotating auxiliary jaw 1034 and fixed jaw or motion
jaw is als~ the same as previously mentioned~
Fig. 2-26 shows another structure of the
two-sectional universal clamping claw and possesses
the universal adjusting function through a cross joint.
As shown in th~ drawing, movable clamping claw 1044
possesses a cen~ral hole 1045. C-~ype auxiliary jaw
seat 1044 is assembled between fixed jaws or motion
jaws in which the movable clamping claw is placed to
make a selection of the circumferential angle and
adjustment of stretch. Both of them also can be
joined togethe~ by the method mentioned above with
respect to Fig. 2-25, and the pan-shaped bearing is
~0 assembled to enhance precision.
Fig. 2 27 shows a universal movable
clamping claw and jaw which is coupled with a
spherical column and can be set firmly. Its
structural characteristics are as follows:
- the jaw part possesses at l~ast a screw hole;
- one end of the support column possesses thread 1048
for rotating and adjusting the screw hole for
screwing the jaw in or out; its middle section
possesses a pattern ring-shaped structure 1049 for
operating and rotating the support column; its
terminal section possesses a screw for screwing
a fixed ring 1050, and locking or releasing
movable clamping claw 1047, and from its terminal
section additionally extends a spherical projected
column 1080, the outer diameter of the spherical
column 1080 being smaller than that of the scr~w of
the terminal section; -
- 44 -
- the outside of clamping claw 1047 is the clamping
side which possesses a plate circular structure,
while its inner side is the coupling side which
possesses a conic structure, its inside possessing
a conic hole. The outside small hole is slightly
larger than the above spherical column and after
being placed, it is processed to be tightened and
let it be smaller than the spherical column to
prevent its falling down and can be free to couple
and move;
- the spherical projecting part extending from the
terminal section of the supportin~ column can
further assemble symmetrical exploded groove 1081
which is at least exploded into two parts, and
possesses elasticity for inserting into the conic
hole of the clamping claw.
Figs. 2-28 and 2-29 show embodiments of the
movable clamping claw which is joined by the
attractive force of a magnet. Its structure includes:
2~ - a movable clamping claw 1051 or 1055 having an arc
surface or spherical surface on its back;
- at the back of the socket, there is a screw hole 1104;
- a bar magnet 1053 is stuck or tightly assembled at
the inside ~f a cup-shaped screw plug 1052; the
inner hole of screw plug 1052 is larger than the
outer diameter of magnet 1053. The magnet, after
being fixed, is of a length which is the same as the
cup-shaped margin of screw plug 1052;
- the cup-shaped margin of screw plug 1052 at least
possesses two opposite gaps, and screw hole 1104
for rotating and screwing the jaw seat in and out;
- non-magnetic permeable anti-scraps cover 1054 is
placed at th~ hole of screw plug 1052;
- the magnetic lines attract the arc or spherical
clamping claw by the above structure.
Fig. 2-30 shows an embodiment of the
movable clamping claw which has a locking hole at its
C
- 45 -
center. As shown in the drawing, in the middle of
movable clamping claw 1056 there is a round hole 1057
for penetrating and locking screw 1057' J and on the
- jaw seat on which the movabl2 claw is placed, there
is a threaded screw hole for screwing the above said
screw in oxder to tighten or release the clamping claw.
The merit of this is to provide one or more sets of
clamping claws to be locked and fixed as a base surface
for clamping the irregularly-shaped work pieces in
order to mill or pla~e, and the extended arc cap 1071
at the margin of the claw is used for stopping scrap~.
Fig. 2-31 shows the structure vf the plate
clamping claw which is extended from the non-adjacent
side~near the outside of the jaw) of the clamping claw
of the movable clamping claw. As shown in the drawing~
at the front side of semi-circular clampiny claw 1058,
there are two screw holes in plate clamping claw 1059
which are longer than the width of the claw surface is
locked on it by screw 1060, after combination of both
of them, one being characterized in that one end at the
side near the semi-circular clamping claw is uniform,
while another end extends along the outside of the
clamping claw near the jaw in order to clamp small work
pieces at the side which is smaller than the radius of
: 25 the clamping claw and prevents sliding of the semi-
circular clamping claw.
Fig~ 2-32 shows a mid-connection-type
clamping claw. It is characterized in that the near
sides of two semi-circular clamping claws 1061 are
rabbeted with respect to each other and a movable pin
1062 penetrates through the middle part to join them
together. The character of this structure is that the
two clamping claw sets can commonly use one arc socket
in order to obtain lower frictional clamping and it is
easy to be manufactured. Especially~ it is connected
by two sets to substitute the original one set o~ the
semi-circular clamping claw and can provide more
- 46 -
points of contact.
Fig. 2-33 shows a three-sectional
embodiment of the connecting~type clamping claw as
shown in Fig. 2-32. As shown in the drawing, two sides
oE middle clamping claw 1063 rabbets clamping claws 1061
to each other and the claws are connected by movable
pin 1062. Middle clamping claw 1063 can make two
different selecti~ns: either the same as the clamping
claw at the two sides, or slightly smaller or slightly
bigger than the clamping claw at the two sides.
Fig. 2-34 shows the structure of a foldable
multi-sectional plate clamping claw. As shown in thQ
drawing, clamping claw 1064 can be made unitary or can
be combined with 1064l. In the middle part, there is
a hole to join with movable pin 1062, and each of its
two sides respectively possesses a long grooved hole
1065. Each middle part respectively penetrates a
connecting rod 1062' and two connecting rods
simultaneously join with the jaw to accept the clamping
force. The merit of this design is that when the
middle projected piece is clamped, the clamping claw
can form a bent curve surface to increase the clamping
point.
Fig~ 2-35 shows plate clamping claw 1066
which is bent inward, and is placed on the jaw having
an arc socket, and constitutes the structure of
mixing movable clampiny claw and fixed plate claw, and
has the ability to clamp irregular-type work pieces by
the inward bent surface and movable clamping claw;
and through plate clamping claw 1066l it is convenient
to clamp a small work piece by clamping the sides of
the work piece.
Fig~ 2-36 shows an embodiment of rabbeted
movable clamping claw 1068. ~s shown in the drawing,
at the front side of the clamping jaw, there are
mounted sectional plate clamping claws 1067 and 1067',
and at the near side of the clamping claw, there is
~",
.,~ .
- 47 -
~ormed a groove 1069 which is larger near the jaw side
after joining and its outside is smaller. The front
side of the movable clamping claw is the clamping
sur~ace which gradually contracts backward. The
terminal section possesses a vertical circular column
structure for rabbeting into gxoove lU69 for swinging
rightward and leftward in order to clamp an irregular-
shaped work piece, and in the removal of said jaw, the
procedures are the same as for the traditional vise.
Fig. 2-37 shows transverse semi-circular
groove 3102 which is transversely placed in the motion
jaw or fixed jaw by auxiliary jaw 3101 which can be
elevationally moved up and down. At the front side of
the auxiliary jaw there are two coupling seats 1301 for
coupling with movable clamping claw 1001 for multi-
clamping directional adjustment.
Fig. 2-38 shows motion jaw 1075 which is
independently driven to rotate, and its front end has
a plate clamping claw for clamping an irregular-
shaped work piece by rotating at least two se~s ofseparate jaws; gives precision sliding between the
above mentioned clamping claws with arc surface at its
back and the socket-type jaw sea~ is one of the
important functions of the structure of this vise,
therefore, the joining structure between the clamping
claw and jaw also must po~sess this design.
Fig. 3 shows a s~ructure which can reduce
the friction between the back of the clamping claw and
arc socket, and due to the precision movement of the
clamping claw is suitable for irregularly shaped work
piecas. Therefore, it lets the contact area between
the arc socket and clamping claw be ~:educed when it
will not affect the stability. As ~hown in the drawing
fixed jaw llU2 with multi-face arc socket and motion
jaw 1205 join with the clamping claw having an arc
back, and the joining of both of them is a
discontinuous small area contact part of the multi-
- 48 -
face contacting with the clamping claw is a plane and
it can make both of them contact by multi-line, or it
is processed to become a small section of the arc
surface to let both of them become a discontinuous arc
contact. This function is formed as shown in Fig. 2-2
and it is that multi-angular shape 1003 which couples
with the arc support surface of the socket to let both
of them become a multi-line contact, or the angle at
the multi-angular back of the clamping claw is a small
arc section which couples with the arc surface of the
socket and becomes discontinuous with the arc surface
contact.
Fig. 3-1 is an elevational view of the
structure as shown in Fig. 3~
Fig. 3-2 is a sectional view
of Fig. 3 showing a fixed jaw and the motion jaw which
possess a multi-surface socket.
Fig. 4 shows a clamping claw which possesses
the arc groove at its back to join with the arc surface
socket in order to reduce the loss of friction. This
kind of structure also can be a reverse structure, that
is, at the arc surface of the socket, there is an arc groove
which joins with the clamping claw with an arc surface
at back.
Besides the above-mentioned transverse arc
groove, one of the socket arc surfaces or back arc
surfaces of the clamping claw assembles the
longitudinal or inclined groove or network uneven arc
surface or hole, and it can also enhance the precision
of the clamping claw. The metho~ of joining the
clamping claw and jaw also is an important part of
this design. Due to the difference and broad joining
method of this kind of clamping claw, the joining
structure of each type of the clamping claws and jaws
will be described in detail as follows:
Clamping claw 1076 as shown in the
embodiments of Figs. 4 and 4-1, wherein its bottom
i5~~
- 49 -
possesses a central column and couples in the hole at
the bottom of the jaw seat for supporting the clamping
claw to rotate.
- The structure of the movable clamping claw
joining with the fixed jaw and motion jaw includes an
arc groove key or dovetail groove which is placed
between the back of the movable clamping claw and the
arc support surface of the jaw or be~ween the bottom
of the movable clamping claw and the bottom of the jaw
in order to couple and slide each other. For example,
the clamping claw as shown in Fig~ 2-15 couples with
the pin of the jaw socket by ~he arc groove at its
back and the bottom of the clamping claw for free
sliding.
FigsO 5 and 6 show the structure of joining
the movable clamping claw and jaw and it is further
characterized by including:
- Movable clamping claws 1~77 and 1078, an inclined
conic structure which possesses a smaller top and
a larger bottom, as shown in Figs. 5-1 and 6-l;
- arc socket of jaw 1103, an inwardly incli~ed arc
socket wlth smaller top and a larger bottom;
- structure of joining the movable clamping claw and
jaw to assemble the non-vertically placed inclined
slot which can prevent the arc support surface of the
socket from falling down at the front side and can
join with the projected column or projected margin
to rotate and join the side and prevent from falling
down in the front side, its joining drawings being
shown in Figs. 5-2 and 6-2;
Further structure of features of the a~ove
clamping claw include a hole at the bottom of the
clamping claw, in which there is a spring and steel
ball which has a radius the same as that of the hole to
substitute for the central column and to enhance
precision. It fuxther poss~sses a bearing in the
joining hole of the jaw for rotation or the axial
A, . . .
- 50 -
column to improve the rotating effect.
Figs. 7 and 7-1 show the embodiment of
another type of joining the movable clamping claw and
jaw, wherein the jaw seat possesses a penetrating
s~rew hole 2902r its terminal section tightly
neighboring a hole with a larger diameter, due to the
bottom of the clamping claw possessing a section of
screw 2901. The section near the clamping claw is
smaller than the screw, and its thickness is slightly
larger than the length of the screw of the jaw seat,
therefore, after screwing the clamping claw therein,
thus forming the structure and function of free
rotation and indirect e~traction. The structure of
screw hole 2902 and 2901 of the abo~e jaw seat and
clamping claw can be placed in reverse with the same
functions.
Fig. 8 shows the further structure of the
clamping claw set. ~he clamping claw set is slightly
cylindrical as shown in Fig. 2-17, and possesses at
least a section of circular arcs to couple with the
socket, and the structure distributed along its
circumference is in toothed shape, convex arc shape,
concave shape, and plane, and its bottom possesses
clamping claw 1015 with a central hole.
According to differen~ shapes of work pieces,
the user can select different shapes of the clamping
suraces to clamp different work pieces; further, if
a different shape of the clamping surfaces is made of
a different material, its application range is
broader. The clamping claw of the above vise is a
clamping claw structure having a multi-directional
different clamping surface. Its main characteristics
are that:
- clamping claw 1015 is slightly cylindrical shaped,
and possesses a coupling hole at its lower part;
- the lower part of clamping claw 1015 possesses a
concave hole and couples with axial column 3001 of
of the socket;
- clamping claw 1015 adjusts the clamping surface by
rotation;
- the clamping surface of clamping claw 1015 is of a
S different shape or is made of different material.
Figs. 8-1, 8~2 show the top view and side
cross-sectional view of this embodiment showing its
main structure.
Fig. 9 illustrates a urther embodlment of
joining the above rotary adjus~able clamping claw set
and jaw. In this embodiment, as shown in Fig. 2-18,
it is almost a cylindrical clamping clàw, and its
bottom and upper parts possess clamping claw 1016 with
a small projected column 1501 for coupling and is used
to join with axial hole 1401 on tne jaw seat and upper
support cover 3002 with a stable hole, and make free
ro~ation to be suitable for various shapes of work
pieces. Upper support cover 3002 is locked at the top
of the jaw seat to stabilize the clamping claw. This
structure has the following features:
- support protect cover 3002 assembled on the upper
part of the clamping claw is locked at the upper
margin of the jaw,
- Movable clamping claw 1016 is adjusted by rotation;
- At two sides of the upper and lower parts of the
movable clamping claw there assembles projected
a~ial column 1501 which is rabbeted at the tool
seat and hole of the upper protective cover, for
rotation and adjustment. Two sides of the upper and
lower parts of the movable clamping claw possess a
concave hole or penetrating hole and couple with the
base seat or motion jaw seat and projected axial
column on the protective cover or penetrating rod,
for rotation and adjustment. The reverse structure
of this design is to change the projected column at
two sides of upper and lower parts of the clamping
claw into a hole, and the upper and lower support
,~
~ 52 -
holes are changed into projected axial or
penetrating rod. Its variation and design are very
simple.
Figs. 9-1, 9-2 are the top elevational view and
side cross-sectional view of the present embodiment
showing its main structure.
Fig. 10 shows laminatea clamping claw 1017
used in substitution for the cylindrical multi-faced
clamping claw. It is made by a lamination method and
is easily manufactured, and is more suitable for
irregular shapes, and possesses the mul~i-sheet convex
arc and toothed face, concave arc, convex arc, plane
type of clamping laminated sheet as shown in Fig. 2-19,
this kind of laminated sheet possesses a round hole for
laminating and forming clamp claw 1017 in order to
rotate and adjust various work pieces. The most
important characteristic is that the largest distan~e
of various clamping surfaces is constantly smaller than
the radius of the back arc of the socket, or in the
same dagree of the arc angles of the socket. It must
possess at least a set of projected points of the
clamping claw which is e~ual to the radius of the back
arc in order to form a support point and rotate to be
interfered by the socketO Four sets of central
columns constitute the above-mentioned transverse
directrix. Important characteristics are:
- The distance between projected points of each
clamping claw and center as shown in Figs. 2-18 and
2-19 < the radius of the arc surface of the socket;
- Under any angle a set of pro]ected points of each
clamping claw set which can contact the arc surface
of the socket will not be less than one set ~o be
used as the support point for accepting the force.
Figs. 10~1, 10-2 are the top elevational view
and side cross-sectional view of Fig. 10 showing its main
structure.
Fig. 11 shows an em~odiment of the structure
- 53 -
of the above clamping claw possessing a cylindrical
axle. Due to its support point being far away from the
two ends, if the distance of each clamping surface of
the clamping claw is unusual and couples with the back
of the socket, the middle section is easy to transform
and be bent by clamping or damaged by excessively
applied force. If the radius distance of each clamp-
ing claw is equal, then its shape is easy to be
limited. The following is the improvement overcoming
the defect, as shown in the figure. The clamping claw
set is c~nstituted by circular axial column 1019
having a groove or arc gap as shown in Fig. 2-20. This
design of clamping claw further assembles stable
- laminate 1018 in oxder to reduce the transformation or
damage caused by the weakness of strength and rigidity
of circular axial column 1019. This novel design of
stable laminate 1018 improves the defect of
transformation caused by the applied force of the
clamping claw of the central column.
Figs. 11-1, 11-2 are the top
and side cross-sectional view of Fig. 11 showing
its main structure. The structural characteristics
of the above clamping claw and jaw including laminate
1018 comprise:
- An axial column 1019 fixed on the fixed jaw or motion
jaw seat; on it there is a circular axial column 1019
which has a groove or arc gap and is not rotary;
- Multi-faced laminated cylindrical clamping claw 1017
possesses a coupling hole in the middle and sheaves
with axial column 1019, and can freely rotate and
does not contact with the arc support surface of the
socket on the jaw;
- Stable laminate 1018 is unevenly placed between
laminated clamping claw 1017 for clamping, and
possesses an eccentric hole, its rear margin
tightly contacting the arc support surface of the
socket on the jaw. Its front margin is shorter than
~A
~,,"~7
- 54 -
the shortest extension distance of laminated clamping
claw 1017;
- A hole of laminated clamping claw 1017 engages with
axial column 1019, and couples with the sectional
gap of the axial column and cannot rotate.
Fig. 12 shows the embodiment of applying a
~lamping claw set as shown in Fig. 2-21 having a
spherical axial column and universally swinging
adjustment on *he vis~. In the drawing:
- The clamping claw set possesses spherical axial
column 1021 inside and outside added ring-shaped

positioning hole on each of its both ends
respectively to couple with said clamping claw;
- A ring shaped fixed plug 1022 to be locked in the
inner ring-shaped slot of motion clamping claw 1020
by the joining way of spiral or screw 1023, and also
having an arc-shaped tapered hole to be coupled to
the upper side of ball-shaped shaft column 1021
- The jaw seat to which protec~ive cover 3005 is
attached having a shaft column 3006 for fixing which
is fixed by a screw 3008 or is tightly screwed in
the screw hole;
- The dimension of shaft column 3006 for fixing is
smaller than that of the motion clamping claw and
the tapered hole of the ring-shaped tapered plug
withou~ interfexing with the free .swing of the
motion clamping claw in its set angle.
From Figs. 12-1, 12-2, its detailed
structure is clear.
The above structure forms the universal
swing structure together with rotatable multi-faced
clamping claws for selecting the required clamping
claw according to various clamping requirements.
Fig. 13 represents another exemplary
embodiment of the above swing clamping claw wherein a
motion clamping claw 1027 as shown in Fig. 2-22 is
provided to clamp a work piece~ In said drawing, the
middle motion clamp claw 1027 has a protrustion to
couple with the ball-shaped shaft column 3009 in the
fixed jaw or motion jaw of the tool seat. Shaft
~ column 3009 has a ball-shaped top and the lower part
of said shaft column 3009 is of a round column shape
to be inserted in~o the hole of the respective jaw
seat or to be joined with a screw therein, and a
protec~ive cover 3005 is provided on said jaw. Shaft
column 3007 with an inwardly concave spherical face is

sectional clamping claw, wherein screw hole 1031
perpendicular to the inclined conic face in its
one face and threaded column 1033 ;s provided on
its other face for mutual turn;ny and rotary
adjustm~nts, since the axial line of its threads
is perpendicular to the inclïned conic face. Changes
in the ele~ational angle will appear when the
axial line between the two-stage clamping claws is
rotationally adjusted. The rotatively adjustable
auxiliary jaw and the fixed jaw or motion jaw are
joined by threaded column lG30 to be turned into
the screw hole for rotationally adjusting the
circumferential angle of the two-stage clamping
cla~ set or for further continual rotations to
adjust the distance of retractions of the clamping

their own inclined conic face respectively and are
joined by the joining face, wherein one side of said
joining face has shaft column 1033 with a spiral and
its other side has a screw hole 1031 for mutual

screw hole, to adjust its angle ~y turning it and to
adjust its distance by retracting it the central line
of shaft column 1033 with a spiral ana screw hole 1031
is perpendicular to the conic face. The auxiliary jaw
and the respective fixed jaw or motion jaw to which
said auxiliary jaw is attached has a disc-shaped
coupling face; thair coupling is also similar in
that one side of the disc-shaped coupl;n~ has a shaft
column with a spiral, while its other side has a hole
~,~
,~

with threads for their mutual turning in and joining
to adjust the distance and angle ~y retractions.

For ex;t and entry, its middle section has an
em~ossed ring 1050 to lock or release motion clamping
claw 1047. From its end section extends a ball-shaped
protruding column part 1080, the outer diameter of this
ball-shaped part being smaller than t~at of the spiral
in the end section.
-- The outer side of clamping claw 1047 is the
clamping side having a flat board round
structure, while its inner side is the
coupling side with a conic~shaped structure
tapered outwardly, its inner side also has a
conic-shaped hole tapered outwardly, the
small hole in its outer side being slightly
larger than the above said ball~shaped
column, and, after being inserted by the
ball-shaped column, is then processed for
tightening up to make said small hole smaller
than said ball-shaped column to prevent the
latter from falling off, but the latter can
freely prevent coupling movemen~s.

Fig. 19 shows the ball-shaped protruding part
extending from the end section of the support column
which can be further provided with a symmetrical cutaway
slot 1081 that is at least cut into two parts with
elasticity to rabbet into the conic-shaped tide tapered
outwardly in the clamping hole.
When the fixed ring 1050 is far away from
clamping claw 1047, the above said structure enables
clamping claw 1047 to swing freely for universal
clamping, and when the fixed ring tightly packs clamping
claw 1047, clamping claw 1047 becomes fixed to clamp a
smaller work piece by its sides.

Figs. 22-1, 23-1 are the cross sectional ~iews
of the structure.
In khis design, the clamping claw set may be
- rotatable freely; how~ver, during its use, it is
constantly necessary to firmly fix or more sets of
said clamping claws to provide a processing datum plane
in an irregular shape as shown in Figs. 24, 24-1, 24-2.
The following will descrlbe the exemplary
embodiments of various motion clamping claws that can
be firmly locked to provide a processing datum plane.
Fig. 25 illustrates an exemplary embodiment
wherein a central screw is used to firmly lock the
clamping claw as such motion clamping claw with a locking
hole in its center, as shown in Fig.2-30. In said
drawing, a round hole 1057 is provided in the middle
part of motion clamping claw 1056 to accommodate
locking screw 1057' to penetrate through therein. The
jaw seat t~ which said clamping claw 1056 is attached is
provided with a small hole 3010 with threads to
accommodate the above-said screw to be screwed therein
for tightPning or releasing said clamping claw. The
merit of this design lies in that it can make one or
more sets of the clamp;ng claws firmly locked in order
to provide a datum plane during clamping irregular-
shaped work pieces, thus facilitating milling or planing
the work pieces. Features of the joining structure of
the above said clamping claw 1056 and jaw are as follows:

the motion clamping claw for rotative
mo~ements, the central position of which
has a screw hole 3010;
~- motion clamping claw 1056 has a central
~ole 1057 which is slightly larger than
the above-said screw hole;
-- a screw 1057' penetrates through the motion
clamping claw to couple with the threaded
hole 3010 in the bottom face of t~e socket

Fig. ~6 represents an exemplary embodiment
showing the arc-shaped notch 3012 which is concentric
to the locus ~f the rotat;o~s of the arc shaped back
of the clamping claw and is pro~ided on the back of the
jaw to which the motion clamping claw is attached. Said
notch 3012 has two widths, of which the width of its
face to couple with -the clamping claw is narrower, and
its width close to the back of the jaw is larger. The
back of each of the clamping jaws 1001 has a spiral
hole 1001' respectlvely to accommodate a terraced rod
3014 one end of which has a nu~ of a diameter slightly
smaller than the part in a larger width of the a~ove-
said arc-shaped notch, the middle section of which has
a diameter slightly smaller than its part with a narrow
width; and the rear end has a diameter smaller than the
spiral in the middle section of said terraced rod to
be turned and fixed in clamping claw 1001. A slip-proof
limit pin 3013 may ~e added to the arc-shaped notch side
of the back of the jaw.

the middle section.
Figs. 27-4~27-7 illustrate exemplary
embodiments of the structure having the clamping claw
locking hole, the features of ~hich lie in:
-- the back of semi-circular motion clamping
claw 1085 has an arc-shaped slot, along
which there is at least a locking hole;
-- it at least has a set of through holes
penetrating through the ~ack of the jaw,
and said hole has a spiral;
~- there is at least a fixing pin 3022, having
a spiral to be inserted into said through
hole in the jaw by turning, there~y coupling
with the slot in the clamping claw;
-- the free status of clamping claw set 1085
is formed when the end of fixing pin 3022
does not enter the locking hole in the
arc-shaped slGt in the back of the clamping
claw;
-- the locked status of clamping claw set 1085
;s formed when the end of fixing pin 3022
: enters the locking hole in the arc-shaped
slot in the back of the clamping claw.
Further, in the applications of the conventional
clamping vise, the parallel small parts for the sawing-off
operations, such as to saw off the screw to become shorter,
~ut the clamp vise of the above-said motion clamping claw
- 68 -
cannot effect th~ sid~ clamping on the parall~l work
pieces with a radius smaller than that of the clamping
claw. The defects are shown in Fig. 28.
To improve the above-said defect, the structure
as shown in Fig. 29 is designed by making the functions
of this clamping vise more complete to have the function
of the conventional flat plate-shaped to side clamp small
work pieces and also to have th merits of the motion
clamping claw~ In the drawing, motion clamping claw 1001
having an arc-shaped back is coupled to the fixed jaw and
the motion jaw respectively, each of motion clamping claw
1001 and the jaw to which said motion clamping claw is
attached is at least provided with a semi-hole-shaped
notch, during rotative couplingt at a specific position,
making said two notches rabbeted to form a hole-shaped
structure 3017, and a fixing pin 3016 is inserted and
coupled to said hole to make the motion clamping claw
set in an unrotatable locked status.
Figs. 29-1, 29-2 are the respective top view
and side cross sectional view.
Fig. 30 shows an exemplary embodiment of the
central plug of two motion clamping claws effecting the
parallel locking. In said draw;ng, the side close to
motion clamping claw 1073 of the same jaw has a longi-
tudinal notch. The clamping vise set i5 provided withparallel plate-shaped position;ng ~lock pin 3018 to be
inserted in the longitudinal notch-in the side close to
the two motion clamping claws of the same jaw. The
dimension and structure of positioning block pin 3018
is to firmly fix the clamping faces of the two clamping
claws of the same jaw, thus forming a straight line or
specific angle and then achieving the functions of the `b
parallel clamping vise. While the positioning block
pin 3018 is remo~ed, it still has the agile functions
of the motion clamping claw.

Fig~ 31 illust~ates an exemplary embocliment
o~ the combined use of the clampiny claw with an arc-
shaped back and the clamping claw with a multi-faced
~ back to be coupled with the multi-~aced socket seat.
As shown in this drawing, two sets of clamping
claws 1001 with an arc-shaped back and two sets of
clamping cla~s 1003' with a multi-faced back can ~e
optionally inserted into the multî-faced socket seats
on the back o~ various jaws, wherein clamping claw 1001
is in continuous contact with the multi-faced socket
seat and clamping claw 1003' is in close contact with
the multi-faced socket seat. When two opposite sets of
clamping claws are all clamping claws 1003' with a multi-
faced back, they cannot rotate to produce functions the
same as those o~ the flat plate-shaped claw. When
clamping claws 1003' with a multi-faced back are
attached to the same jaw, both o~ them form an unrotata~le
straight line or curve angle to match motion clamping claw
1001 for clamping the work pieces ïn a multi-faced way.
Features of the structure of the combination-type
clamping vise of the above-said motion clamping claw and
the clamping claw with amulti-angular back having a
multi-angular-shaped socket seat are as follows:
-- the clamping vise has four sets of clamping
~5 claws, the clamping jaw socket ~eats on
their jaws having at least two sets of non-
arc-shaped polygons;
-~ at least two sets of the clamping claws with
an arc and at least two sets of the clamping
claws with a polygonal back to notch the
respective polygonal socket seat are set in
the non-arc-shaped polygonal socket seats
respectively;
-- the clamping claws are the ones with their
positions mutually exchangeabla and having a
polygonal back and opposite to the clamping
claws with an arc ~ack or the clamping claws
~ 2
- 70
having a back in the structure the same
as the former.

show~ în said drawing each of the ixed jaw and motion
jaw has two sets o the arc-shaped socket seat with an
arc-~aced back respectively, said four sets of motion
clamping claws 1088 being coupled by a dovetail slot

along the non-adjacent sides ~the outer sides close to
the jaw~ of the fixed jaw and motion jaw, a section of
the flat plate clamping claw structure as shown in Fig.
2-31. In said drawing, the front of semi-circular
clamping claw 1058 has two screw holes in which flat
plated clamping claw 1059 longer than the width of the
claw face is locked. The feature of the joining of
both of them lies in that their one end is flat and
with the close side to the semi-circular clamping claw,
their other end extends along the outer side of the
clamping claw close to th jaw to avoid the sliding of
the semi-circular clamping claw, when said semi-circular
clamping jaw clamps with its sides small work pieces
of a diameter smaller than that of the clamping claw.
Features of the clamping claw sets are as follows:
-- the non-adjacent sides of the motion
clamping claw sets have the structural
extension of the flat plate-shaped
clamping claws;
-- the outer rim of the jaw seat and the
motion clamping claw appear in a flat
plate-shape and when the clamping claws
are in a sideway line they ~ecome clo~ely
coupled together.

the flat plate-~haped clampïng claw 1059 in a width
larger than that of the clamping claw face, which is
joined by screw 1060 in way of slightly deflecting to
the outer side. The outer side angle of th~ ~aw limits
the outward turning angle of the above-said motion
clamping claw.

which both sides of the fixed jaw and clamping jaw have a
separately installed flat board-shaped clamping claw 1082,
and between the fixed jaw and the clamping jaw, four sets
of clamping faces oppositely formed ~y the motion

Fig. dsS illustrates that for the two ~ets of the
cc~nnection-type clamping claw fitructure ~hown in Fig. 41,
the back arc is further changed to the ~lat plate shape to
enlarge its bent angle ~imilarly, and the action of the
l~ngitudinal ~lot 3023 is changed to and replaced by the
long filot-type hole in both side~ of the clampinq claw.

respectively through which a link rod 1062' penetrates
raspectively, said ~wolink rods ~imultaneously joining the
jaw to bear against the clamping pressure~ ~he merit of
this design lies in that when i~ clamps a work piece with
a protruded part in the middle of said work piece, it can

Besides, the above-said mutually cro3~ coupling
structure, the bendable multi-stage flat plate shaped
clamping claw may al~o be that like the above-said
multi-~tage connection-type clamping claw, wherein there
further mutually extends a limiting structure~ A~ shown
in Fig. 46 the two-sheet-type clamping claw mutually cross
coupled ~ide has an extended ~ection 1070, when the
clamping face~ of various flat plate-~haped clamping claws
form a straight line. The extended section 1~70 of
various clamping claws is tightly ~ecured to the back of
the flat plate clamping claw that it cross couples by
limiting the middle section of aid bendable ~ulti stage
flat plate-shaped clamping claws to concave inward, or to
form a straight line without any protrusions, thus
achieving the ability of the motion clamping claw to clamp
irregular-shaped work pieces, and may be also like the
flat plate-shapad clamping claw to clamp ~mall work pieces
by its sides. Fig. 46-1 is a cross sectional view of the
embodiment shown in Fig. 46.
Fig. 48 shows an exemplary embodiment of the
clamp vi e formed by joining the three sets o~ flat
plate-shaped clamping claws, each of their mutually cross
coupled sides having a structure of the limiting section
1070 respectively. Its actions and applications are
2~ similar to those previously described. Fig. 48~1 is a
cross sectional view of Fig. 48. Resides, Figs. 45-48

faces of the Y-type fixed jaw 1122, the Y-type motion jaw
1222 and the multi-stage flat plate-shaped clamping claw
: 30 are the ja~ face wi~h a concave arc in its middle part and
a transver~e line on its both ~ides. As shown in Fig.
46-2, when it clamps a small work piece by its ~ides, the
clamping claw is directed to form a 6tabili~ed parallel
clamping (the exemplary embodiment o$ the work piece as
35 sho~m in Fig. 46-4). Fig. 46-3 is a cross ~ectional view
of the ~tructure shown in Fig. 46-2.

With regard to the auxiliary displacement~ of the
jaw seat, ~he above-said v~rious e~emplary embodiment~ of
the clamping structure~ are only li~ited to the
displacements of the clamping claws to adapt to
irragular-6haped work piece~, and the adaptable ~cope is
still limited. In particular, it i6 rather hard to adapt
to work pieces having larger irregular-3haped profiles, or
it i5 impossible to make all clamping claws tak~ part in
clamping guch a work piece (as shown in Fiq. 50-5~, and it
10 i8 also difficult to adapt the work pieces with a
rectangular profile (a~ ~hvwn in FigO 49-53, to ~urther
improve its applicable scope. m e better ~ean~ are to
make the jaw ~eat efect the tran~ver~e drive, swing and

1~ embodiments of thç improved clamping work. Various design
changes concerning the above-said jaw structure will be

clamping claw, the construction of which is that the
coupled face of auxiliary jaw 12~5 and motion clamping
claw 1201 is in a straight line coupling. $he dove-tail
structures mutually rabbet and couple and also effect the
opposite sliding movements. A limit transverse ~lot is
provided in the coupled face of the dovetail slots of the
auxiliary jaw and motion jaw, and two longitudinal screw
holes 3026 are provided in the motion jaw tv accommoda~e
the limit ~crews 3027 to be turned therein for limiting
their transverse displacement quantitie~. Auxiliary jaw
1225 has two sockst seat~ having an arc-~haped back to

arc-shaped dovetail structures mutually rabbet and couple
and also effect oppoRite ~liding movements. The coupled

motion jaw has a limit transverse 610t, and two transverse
20 screw holes 3026 are provided in the motion jaw to
acco~modate limit screw 3027 to be turned therein for
limi~ing its turning angle. Auxiliary jaw 1226 has two
socket seats with an arc-shaped back to set up motion

Figs. 50-5 and 50-6 show the jaws of the vi~e

Besides the exemplary embodiments ~hown in the
above-saîd Figs. 49 and 50, the auxiliary jaws 1225, 1226
may also b~ between the fixed jaw and the clamping claw,
or further on the motion jaws and the fixed jaws. A
further design of the displacement structure of th~
above-said jaw ~eat is that the motiDn j2W itself is a
rotatable ~ructure to achieve the enlargement of its
~pplicatory scope with respect to irregularly-shaped work
pieces, and various exemplary ways are described as
follows.

Fixing pla~e 2301 provided on its bottom is turned and
25 fixed by screw 2401 in screw hole 2601 in coupling column
2101 to join both of them. The back of motion ~law 1201

rod 1601, and the guide rod positioning screw i~ insert~d
and turned into guide rod positioning screw hole 2701 on
3~ its bottom, thus making the gu;de rod positioned. The
combination of ~his tructure makes the jaw seat slide
back and forth on the guide rail by the round coupling
column and also effect6 the rotative ad~ustments, thereby
increa~ing the adaptability of the motion clamping claw
35 ~et thereon for irregular-~haped work piece~.

Fig. 52 illus~rates another exemplary embodiment
of the above-said rotary structure of the ~otion jaw. In
this ~tructure, parallel glide block 2202 of motion jaw
1201 to be coupled with ~he guide rail is a separate
design. The two sides on the bottom of parallel slide
blocX 2202 have e2tended edges to couple with the bottom
of the ~lide rails. A round column iA provided on ~aid
motion jaw, the upper part of said round column having a
section with threads, and a vPrtical coupling hole 303~ is
provided at a place close to the back of the motion jaw
and is a two-stage terraced hole with a larger diameter in
the upper part and a 6maller diameter in the lower part
~ection, being equal in length to or slightly shorter than
that of the non-threaded section of the round column on
parallel slide block 2202 for agile rotation. Both of
them are turned and tightened by nut 2203 and wash~r 2204
on the threads at the top of the round column.
Fig. 52-1 is th~ top view of this structure; and
Fig. 52-2 is its side cross sectional view.
Besides, the above-said joining way may also be
such that the buckle ring (a~ shown in Fiy. 52-3) is used
or a screw is used in the screw hole provided on the end
of the round colu~n for firmly locking.
Fig. 53 shows the reverse structur of that
25 illustrated in Fig. 52, wherei~ a central column 2207 is
provided on the bottom of motion jaw 1201. The end of the
central column has a buckle ring slot and ~wo sides of the
bottom of parallel slide block ~205 have extended edges to
couple with the bottom of the slide rail. Parallel slide
30 block 2205 has a central hole 2206 to accommodate central
column 2207 on the bottom of the above-said motion jaw
1201 to penetrate therethrough, and both of them are
joined by washer 2208 and outer buckle ring ~209 for the
agile ro~ation of ~he motion jaw.

A further 6imple design change o~ the joining way
between both of them is featured by the provision of
threads or a screw hole on the end of central column 2207
for firmly locking and joining by a nut or ~crew. Fig. 54
illu~trates another exeMplary embodiment of the rotary
structure of the above-said ~otion ja~ and is applicable
to the structure of the post-or-tube-~haped parallel
rod-type guide rail, as ~hown in the three~dimen~ional
view in Fig. 54. Its main feature lies in that the bottom
of the motion jaw is in an I-shaped structure which has a
transverse notch ~lot 3032 to couple with two parallel
rods 3031. Both of the parts above and below æaid
transverse notch 610t 3032 closely stick on the parallel
rods. The distance between the inner walls (acing notch
slot 3~32) of the left and right ~lots is _ the di~tance
between the inner sides of two parallel rods 3~31, and the
distance between the other 6ides o the two transverse
notches is slightly larger than that of the two parallel

Be~ides, the parallel 810t hole 3034 shown in Figs. 56, 57
further has a stabilizatio~ plug hole structure. ~his
~tabilization plug 3037 has a hole slightly larger ~han
~he parallel post or pipe to smoothly and reciprocatingly
slide, and its outer surace has a section which i8 conic
in a shape mutually complementary to the flat ~haped hole,
and i6 cut at least into two vanes ~o be in6erted into the
flat 610t hole in the motion jaw. The lenqth of said
~tabilization plug is such that after eaid plug is
inserted into the flat holes, it ~till ~lightly projects
over the other ~ide of the flat plate-shaped clamping
board, and the installation direction of the tabilization
plug is optionally selected. If the upper lower, left and
right part3 o the coupling hole in the bottom 8eat of
motion jaw 1201 are larger ~han the structure that the two
parallel p~5t8 ~erve as the guide rails for the motion jaw
to universally adju~t the direc~ion, the stabilization
plug must be an embracement ~ype s~ructure at least
embracing above 180. It~ features are a~ follows:
-- it has a hole lightly larger than the
parallel column or pipe to ~moothly and
reciprocatingly ~lide;
~'
87.
-- its outer ~urface has a conic ~ection which
is in a ~hape mutually complementary to the
round hol~ and is at least cut into two
vanes to be inserted into the larger round
hole slots in the motion jaw;
-- the length of said stabilization plug i~
such that a f ter b~ing inserted into the
hole, it ~till ~lightly projects over ~he
other ~ide of the flat plate-6haped
clamping board;
-- the coupling hole of the above-said motion
jaw may be a flat or round one as an
inclined conic-shapea hole which is
stabilized ~y ~he parallel mutual
complementary shaped stabilization plug,
-- the above-~aid stabiliza~i~n plug may be set
in a reveree direction.
By the same token, ~or tha exemplary embodi~ent6 shown in
Figs. 56, S8 and 59, the ring can be sl~eved between the
~eparate guide rail and the transverse parallel slot hole
to have a similar struc~ure: therefore, in applications,
: this stabilization plug 3037 i5 inserted into transverse
parallel ~lot holes 3033, 3034, 3036 to make the motisn
jaw not swinging, and when the stabilization plu~ gets off
the transverse parallel ~lot hole, the motion jaw can maXe
angular adjustments to clamp irregular-shaped work pieces.

Besides, when it clamps the irregular-shaped work
pieces, the three-dimensional irregular-shaped work pieces
as shown in Figs. 62-62-3 are often encoun~ered. To
precisely clamp this kind of work pi~ces, in addition to
the above-said various exemplary embodiments. the
following various structural design e~bodiments are used
to achieve this objective.
Fig. 63 illustrates one of ~uch structural design
embodiments. In this drawing, the features of it~ main
structure lie in that between the motion jaw 1201 and
round slide block 2101 or parallel slide block of the
slide guide rail, each of them has cross-rabetting arms
2209, 2211 respectively which can el~vate or dip forward
and backward and are protruaing out in their middle part
and tapered upwardly in their front and back eides. Each
said arm has a through round hole to be joined by a join
pin 221~ and a buckle ring 22130 When the ~lide block is
in a round shape, it combine~ the forward and backward
elevational ~otions to form a universal clamping, and when
the slide block is a parallel slide block, it may form the
forward and backward deviation and inclination to clamp an
inclined conic face.

block structure.
Figs. 64-64-4 illustrate exemplary embodiments
applied to the flat plate-shaped clamping claw. Except
for the clamping claw, the remaining variou~ structures
are the same as those shown in Fig. 63.
Figs. 65-65-4 show an exemplary embodiment o~ the
str~ctures ~hown in Fiqs. 63, 64 further having a

~3C~
structure to limit the elevational angle~. In thie
drawing the transver~e joining pin 22~2 forma the forward
and ~ackward elevational and inclinational center, its
bottom close to the driYe guide rod ha~ an elevational
motion limit plane 2213 which contacts the guide rail at
the maxi~um limit angle to limit its ~aximum work angle.
Figs. 66-66-4 illu~trate the exemplary
embodiments showing the elevational motion ~tructure being
applied to the flat plate-shaped clamping claw.
1~ Fig. 67 shows an exemplary e~bodiment of the
structure o~ the motion jaw having a ball-shaped joining
structure for universal adjustments; in this drawing,
motion jaw 1201 has a vertical central hole 2219, ~he
bottom of said hole 2219 ha~ing a ball-shaped and
up-shaped socket seat 2216~ and a ball-shaped column
central rod 2214 with a ball-shaped head in its front
~ection, and a spiral in its end penetrates through saia
socket ~ea~ 2216 and also ~aid round column-æhaped bottom
~eat 2101 and then nut 2217 and sprin~ wa~her 2218 firmly
lock said central rod 2214; and seal plug 2215 is u~d to
Real off vertical hole 2219 in the motion jaw to avoid the
falling of scraps or chips.
Fig. 67-1 is its æide cross sectional view. As
seen from this drawing, the ball-shaped ~ocket eat on the
2~ bottom of the motion jaw protrudes out of the bottcm face
of the jaw, so the above-~aid structure makes the motion
jaw effect universal swings with the ball-shaped head of
the central column 2214 having a ball-shaped column in the
center to clamp various work pieces in different 6hapes.
Further, as ~hown in Fig. 6~, the side close to the drive
guide screw on the bottvm o~ the motion jaw has an
elevational motion limiting plane to contact the guide
rail at a set maximum elevational angle and to limit the
maximum work angle. Additionally, in the above-said
rotatable motion jaw 6tructure, the manner o~ joining its
guide ~crew 1601 and ~otion jaw 1201 includes: ~he motion

9o ~
jaw seat has a hole 2220 to provlde the space ~or ~he left
and right 6winging dif;placements of the guide ecrew and to
accommodate guide 3crew 1601 penetrating therethrough: the
end of guide gcrew 1601 has a ring-shaped con~ave 610t
2221 to couple with ~crew 2501 on the ~otion jaw; ~r a
vertical hole in the end of the guide scxew to
accommodate the pin or rod vertically installed on the
motion jaw to penetra~e ~herethr~ugh, thus making the
rotatable jaw effect a swinging coupling. The coupling
structure of the r~tatable and elevation~motion universal
swinging motion jaw and drive structure include one end of
guide ~crew 1601 having a ball-body-~haped structure
2226. Motion jaw 1~01 has a vertical through pin hole
2228 having a ~mooth round hole 2227, in which a pin 2229
is provided to penetrate through the joined ball body, and
drive rod through fixing enclosure 2230 having a
ball-shaped arc face is in~talled on the guide ~crew and
is locked in Ccrew hole 2232 in the back of the motion jaw
to join the arive rod and the motion jaw. Additionally
the above-said ball body and the ~nd of the guide screw
may al~o have threads for coupling.
The above structure formed by the above-~aid
swinging motion jaw to clamp the irregular-~haped work
pieces may also be further formed in such a way that
elevation-motion adjustable auxiliary jaw 3101 i8 set
between mo~ion clamping claw 1001 and motion jaw 1201 or
ixed jaw 1101, ~uch that the m~tion clamping claw and the
elevation-motion adjustable auxiliary jaw 3101 have ~he
ability to clamp the work pieces in different ahapes.
Fig~ 68 shows another exemplary embodiment of
this design. In this drawing, 1101 is the fixed jaw, 1102

auxiliary jaw 3101, and its round hole-shaped transverse
slot is larger t.han 180 to avoid the auxiliary jaw
~lipping off from the front. ~he ansle between the front
protruding part of said elevation-motion auxiliary jaw
3101 and the center of the ~ircle is smaller than 180 for
upward and downward elevational motions. The botto~ has a

The drive direction of the sideway clamping claw
and that of the motion jaw in the above-said Btructure i8
at an angle of 90O Its further design may be ~uch as
~hown in Fig. 85, wherein the three-way drive motion jaw
is in a three-way clamping type designed ~o that the
contact shafts do not intersect to further enlarge its
clamping scope to improve the defect ~hown in Fig. 85-3,
wherein if the clamping direction6 of the three ~ets of
clamping claws are such that the central ~hafts inter~ect,
this makes two 3ides or more in a width of its clamping
claws smallar than that of the work piece, so that it is
impossible to clamp irregularly shaped work pieces. In
Fig. 85, there is shown an exemplary embodiment of this
three-way clamping structure with its central shafts not
intersected. In this drawing, machine seat 1904 has a
three-way drive guide rail on which there are three sets
of motion jaws 1201 and support arm 1801 with a spiral
hole in~ide. The back of the clamping claw 1130 of the
coupling single set of the motion jaw has a round arc.
The three sets of motion jaws each having a separa~e drive
guide rod respectively are 6uccessively set at an angular
difference at 120 between two adjoining said drive guide
rods, and the central shafts of variou6 said jaws do not
intersect, but form a small triangle in the center to
clamp work pieces of various types. The construction of
the three-way jaw further has at least two sets of motion
jaws 1201 reciprocatingly driving in the slide guide rail,
and the other direction in fixed jaw 1101. Each of said
three set~ of motion jaws ha~ a motion clamping jaw 1130
respectively. The front of each of the various jaws has
an arc-shaped ~ocket seat 1301 respectively and is also
~et a semi-circular motion clamping claw 1130
respectivPly. The width of various clamping faces is at
least twice the length of the ~ide of the said triangle
formed by the intersection of the central sha ts of the

above-said jaws in the center. The formation of the
above-said various clamping claws may also be con~tituted
by two set of semi-circular motion clamping claws 1130
and one set of the motion jaws or fixed jaw, each having a
flat plate-shaped clamping claw 3201 to clamp the
irxegular-shaped work pieces.
Yig. 85-1 is its gide view. Fig. 85 2
illustrates an exemplary embodiment of its function. The
above-said embodiments are exemplary embodiments of
various designs for the said clamping structure of the
clamping vise, its another integrally forming said
clamping vise in ~he structure of a machine seat, since a
good machine seat can provide a stable junction for
semi-permanently fi~ed items ~uch as the clamping vise
itself, and machinery work bench, worX table, etc., and
further provide directional adjustments for the clamping
vi~e. Various improvement means are described as follows:
Fig. 86 shows a machine seat wherein the long
strip arc-shaped adju~tment face joins the machine seat to
adjust the directions of the clamping vise. In this
drawing, for the structure with a lower machine seat 3220
in an E-shaped long strip arc form, to its bottom is
attached machine seat locking guide screw 3221 and
clamping block 3222. The bottom of the clamping vi~e
itself has a rectangular ~lot hole 3233 in a width
slightly larger than that o~ the round arc on the top of
said lower machine seat to accommodate the arc-shaped
structure on the top of said lower machine seat to be
inserted thereinO Through hole 3226 on its both sides
accommodates joining screw 3227 to penetrate therein.
Fixing block 3224 i8 a plate-shaped long strip block and
its two sides has ~crew hole 3225 to join fixing block
3224, and its middle part has a ~piral hole 3228 to
accommodate an angle locking bolt to be turned therein,
and its si~e is slightly wider and longer than that of the
rectangular 810t in the ~ottom of the machine ~eat. Screw
101 .
3227 is locked on the bottom of the ~achine seat to join
the lower machine ~eat and the bot~om of the clamping
vi~e. A damping block 3230 has a bottom in a convex arc
~hape, and i~s middle part hag a sunk round 30cket hole
5 3031. A ~emi-circular gap is formed between the top round
arc on the lower machine seat and the bottom seat of the
cl~mping vise, after the top round arc on lower machine
seat to be set in from its side joins the bottom seat of
the clamping vise. After the angle locking bolt 3229 is
turned and penetrateq through ~piral hole 3228 in the
fixing block, said bolt tightly presses again t the socket
hole 3031 on the bottom of damping block 3030 and is
tightened or released to make the gap between the bottom
seat of the cla~ping vise and the lower machine seat
~lackened for adjusting the angles or locXing ~tatus.
Fig. 86-1 is its side cross sectional view; Fig.
86-2 is its front view; and Fig. 86-3 is its bottom view.
Fig. 87 shows another exemplary embodiment of the
invention. The structure shown in Fig. 87 is designed
such as to further provide a dual-purpose machine seat for
horizontal and vertical locking use6 to vertically clamp
the edges of a work table or to be locked on the work
bench of a drill, and also effect angular adjustm~nts.
Its construction is described as follows.
The end of the e-shaped clamping structure close
to locking bolt 3221 of said lower machine seat bends 90
toward the direction of the operational handle of the
locXing bolt of the lower machine seat, and also extends
and i6 provided with a hole or semi-circular notch 3232
3~ for horizontal locking, while the other end of the
e-~haped clamping structure bends 90 successiYely three
timeS tvward the inner side of the e-shaped structure, and
then bends back to closely lean against the inner side of
the e-shaped ~tructure. A hole or semi-circular notch
3232 for the horizontal locking is provided in the section
between the first and second 90 bends. ~he section
~Z6~

between the second and third 90 bends aerves as a
Vertical locking face, and its angular adjustment
structure is the same as that shown in Fig. 86.
Fig 87-1 is its side cross sectional view; Fig.
87-2 is its front view; and Fig. 87-3 iR a bottom view.
Fig. 88 illustrates an exemplary embodiment of
the structure having two locking faces and angular
adjustable functions. When the clamping vise is used with
a work table, sometimes it has to clamp work pieces set on
the floor in a suspension ~ay, and the locking of the
clamping vise uses its bottom to join a C-shaped clamping
seat on the one hand and also needs to be joined to the
back of its fixed jaw; and further the opposite angle
between both of them is made adjustable to facilitate the
clamping of various types of work pieces in different
circumstances. In this drawing, 3240 i5 a C-shaped
clamping seat, 3221 is the machine seat locking bolt which
penetrates through a screw hole 3241 in one side of the
clamping seat and then couples with a clamping block
3222, The middle section of the C-shaped seat has a
multi-angular hole 3246 and screw hole 3241, while the
opposite side has another multi-angular hole 3248~ The
fixed jaw face of the clamping vise has a multi-angular
hole 3245, and the bottom seat also has at least a
multi-angular hole 3247. The way of the joining and
angular set~ing structure between multi-angular holes
3248, 3246 in the C-shaped seat and multi-angular holes
3247, 3245 in the clamping vise is. the shapes and sizes
of various said holes may be either the same, or ~hey ~ay
be polygonal, in which some are twice the size of others,
and the distances of their opposite sides are equal. Then
a middle polygonal locking section of an outer diameter
~maller than that of the head but larger than the 6crew is
provided between the head of locking screw 3242 and the
acrew, and its length i5 _ the thickness of the
multi-angular hole in the C-shaped seat + the thickness of
~2~
103.
the multi-angular hole in the cla~ping vi6e the
thicknes~ of the thicker holes of them. The ~hape and
~ize of the polygonæ in the locking section are such as to
couple the through-hole polygon~ with the multi an~ular
hole in the C-shaped ~eat, and the ~ulti-angular holes in
the bottom of the clamping vise concentrically overlap hy
an equal angular extent ~hus at lea~t pos6ibly locking the
two opposite ~ides (or angles) of the polygon with equal
angles, and thereby maXing the bottom of the clamping vise
and the C-shaped Geat non-rotatable. An absolute
requirement is that the cro~ section of the locking ~crew
must be at least in a 6hape different from that o one of
- the two holes to be penetrated through by this locking
~crew. The aforesaid construction i~ used to 6elect
various angles of the clamping vise to be fixed on the
work table.

Fig~ 88-4 shows the middle section having an
equal-la~eral polygon-~haped locking screw 3242.
The way of joining the C-6haped clamping seat and
the clamping vise shown in Fig. 88 may be effected by
meang of a further structure wherein the two incline~
effect the function of universal adjustments. Its
structure, BS illustrated in Fig. 89, includes a universal
locking ~crew 3250 having a ball shaped head and two
30 inclined conic~shaped middle blocks 3251, 3251' and fixing
nut 3252. A6 shown in Fig. 89, the head of ~aid universal
locking ~crew 3250 is in a ball shape, its upper end has a
polygonal screw head (or inner polygonal crew ~tructure),
and its lower end is a ~mooth round rod, with thraads on
3~ the end. Inclined conic-~haped middle block6 3251, 3251'
are in the form of a round ox polygonal block,
104.
respectively nonparallel between their top ana botto~, and
have an inclined conic-shaped hole in their middle part
respectively. Their top and bottom faces are provided
with patterns indented by pressurization BO ae to enhance
friction. In use, the two inclined conic-shaped middle
blocks are overlapped on their faces with a smaller hole
and then set between the C'-shaped clamping seat and the
clamping vise seat to accommodate æcrew 3250 of the
universal clamping seat to penetrate $hrough therein, and
then to be locked by a nut. The over-lapping angles of
the two sets of the inclined conic-shaped middle blocks
serve to adjust the bending angles, and said two inclined
conic-shaped middle blocks rotate simultaneously to adjust
the direction of the bent angle, thus making ~-shaped
clamping seat 3240 and the clamping vise effect universal
adjustments.

and fixed on a semi-fixed article (for inRtance a work
bench). Middle seat 3055 with inclined aces is of a
triangular plate-shaped structure, the inclined ~ide of
105,
which has a locking hole 3059. ~ocking scrzw 3060 and
locking nut 3061 are locked in locking hole 3057 in the
inclined face of the clamping geat having inclined sides
to tightly lock the two inclined sides for the bent angle
adjustments. Locking hole 3058 is also provided to engage
with the locking hole in the clamping vise. Various
locking holes may be made in a polygonal hole as ~hown in
Fig. 88, and then matched with locking screw 3242 to set
and firmly lock its angles.

Figs. 94~54-3 illustrate exemplary embodiments in
which the rotary coupling parts shown in Fig. 92 are
replaced by and made into a polygonal hole and locking
screw 3242 to effect the angle setting and locking
functions.
Besides, the machine seat of the conventional
clamping vise is usually fixed on a table ~op, and its
height is constantly unadjustable. It ~ometimes may have
an improper height within several inches to user~ of
differing body heights, with the result that this easily
makes them tired over an extended time of work.
Fig, 95 shows a structural design of the bottom
of a height adjustable and angle rotary adjustable
clamping vise, including the machine body of the clamping
vise. Its lower side has structure 3089 with a hollow
cylinder or solid cylinder having outer threads to engage
with bottom seat 3090. In this design bottom seat 3090 is
a round ring-shaped structure, its circumference having a
projected beam 3091 with a round hole 3092 to be locked on
2G the table top. Viewed from its top, bottom seat 3090 has
a sunk inner ring-Rhaped hole 3093 to accommodate
arc-shaped block 3094 having at least two ~ections with
inner threads between said arc block~. A pin 3G95 fixedly
set on the botto~ rim of the various said section-type
inner rings limits the sliding. Various said arc blocks
3093 with inner threads are of equal or angular length for
identifying their respective rotary sequence and for
accommodating the hollow cylindrical outer ring threads on
machine body 3089 to be turned therein. The arc 3ections
Of ~aid arc blocks are inserted into r~spective sunk inner
L ing holec 3093 in the bottom seat. At least a ~idewise
screw hole 3096 is provided in its middle part to
accommodate a screw handle 3097 to be turned therein from
outside to push the plate-shaped arc blocks with inner
threads for locking or rele~sing machine body 3089. Thus

the above-said structure can achieve the very high optio~s
and adjustments of the horizontal angles for the machine
eeat.
Fig. 95-1 is a top view of the machine seat; and
Fig. 95-2 is ~he side view of the machine seat.
Fig. 96 shows the two-piece structure as upper
machine body 3098 and middle machine body 3099 further
made from machine body 3089 æhown in Fig. 95. The lower
~ide of the upper machine body i8 in an inclined face
4000, its center having a hollow or solid cylindrical
structure 4001 with outer threads perpendicular to the
said inclined face. The joining of the lower ~ide of
middle machine body 3099 and the structure of bottom seat
3090 is the same as thP above-said body 3099 and bottom
~eat 3090 as shown in Fig. 95. To effect height and
horizontal angle adjustments and locking, the upper side
of middle machine body 3099 has an inclined face 4002
complementary to the inclined face on the lower side of
the upper machine body. Said inclined face 4002 has a
vertically sunk ring-shaped hole 4002 to accommodate at
least two-section arc-shaped block 3094 with thread~
inside to be turned therein, between various said blocks.
A pin fixedly set on the bottom rim of the ring limits
their sliding. Various plate-section-typc arc blocks 3094
with inner threads are of equal or unequal lengths for
identifying their respe~tive rotary ~equence and for
accommodating the hollow cylindrical ou~er ~hxeads in
machine body 3098 to be turned therein. The middle part
of the arc secticn of the arc blocks to be ins~rted into
the concave inner ring 3093 on the bot~om seat ha6 t
leas~ a sidewise thread hole 3496 to accommodate a screw
handle 3097 to be turned from outside to push the
plate-section-type arc blocks with ~hreadæ inside for
locking or releasing machine body 3089. Thus the
above-said structure can achieve very high options and
adjustments of the elevational angles for the upper
machine body.

Fig. 97 ~hows an exemplary embodiment of the
structure of the ~olid cylindrical coupling inclined face
with a ring-shaped slot for universal adjustments as ~hown
in Figs. 91, 92 and now &et on the machine body of the
clamping vi~e, mainly having upper machine body 3098,
middle machine body 3099 and bottom seat 3090. In this
drawing, the lower side or upper machine body 3098 ha~ an
inclined face, from the center of which p~rpendicularly
protrudes a hollow or solid cylindrical 6haft column 4004,
the end of which has a ring-qhaped ~lot 4005. The upper
part of said middle ~achine body has an inclined face 4006
complementary to the inclined face Gn the lower side of
said uppex machine body. Said inclined face 4006 has a
perpendicular sunk round hole 4007 which couples with
projected shaft column 4004 on the lower side of the
machine body. The side of round hole 4007 in the upper
6ide of the middle machine body has a ~idewi e thread hole
20 4008 to accommodate screw handle 4009 to be turned therein
for lo~king or releasing. The lower side of the middle
machine body has ctructure 3089 in a hollow or solid
cylindrical column and having an outer spiral ~o couple
bot~om seat 3090. In the drawing, bottom ~eat 3090 is a
round ring-shaped ~tructure, its circumference having a
projected beam having a hole 3092 to be locXed on the
table. Viewed fro~ its top, hole 3093 with a ~unk inner
r~ng i8 to accommodate arc block 3094 having at least two
oection6 with inner thread~. Between ~aid arc blocks, a
pin 3095 fixedly ~et on the bottom rim of the inner ring
limits the sliding of vari~us blocks. Yarious said plate
section-type arc blocXs 3094 with inner threads are of
equal or unequal length for identifying ~heir respective
rotary sequence and for accommodating the hollow
cylindrical outer ring threads on machine body 3089 ~o be
turned therein. The arc ~ections of said arc blocks are
110 .
inserted into respective sunk inner ring holes 3093 in the
bottom seat. At lea~t a ~idewise ~crew hole is provided
in its middle part to accommodate a screw handle 3097 to
be turned therein from outside to push said plate-shaped
arc blocks with inner threads for locking or releasing
machine body 3089. Thus the above-said structure can
achieve very high option~ and adjustments of the
hori7ontal angles for the machine seat.
Fig. 97-1 is i~3 side cros 6ectional view; and
Fig. 97~2 is i~s bottom view.
The bottom seat illustrated in Fig. 97 has
besides a further structural design with a flexible
center. Since during tooth tapping or hole boring, if the
center is not quite right, in the light cases, all the
teeth or holes thus made are deflected away from the
original center, and in the serious cases, the knife tools
are damaged, so this flexible cen~ral bottom seat
structure is a design to improve such a defect, since it
has the ability t~ permit errors within a fixed amount
without hindering the processing work.
Fig. 9B illustrates another exemplary embodiment
of the invention. Its main structure comprises the
coupling seat and bottom Reat of the upper machine body.
Upper machine body 4010 constitute~ the body of the
clamping vise, and its upper side has an arm support,

joining between said coupling seat 4012 and bottom seat
4013, or to turn downward to separate bottom seat 4013 and
coupling seat 4012 for both of them in a flexible float
joining. Ring shaped structure 4014 may have a round hole
4028 or spiral hole on its ~ide to accommodate an
operational handle to be inserted therein. A positive
acting ring-shaped spring 4017 is a strong concentric
ring-shaped spring and i set concentrically with
ring-shaped adjustment structure 4014, and its other end
is locked on coupling seat 401~. ~he lower side of
c~upling seat 4012 is to lock the other end of said
po~itive acting ring-shaped spring and fixing plate 4025
and locking screw 4026 lock its top. The bottom seat is

Fig~ 98-1 is its side cross ~ectional view and
Fig. 98-2 is its b~ttom view.
Besides, in the above said exemplary embodiment
sprin~ 4017 can be xeplaced by a 3emi-ball-shaped seat
4070 from the center of which outwardly extends a slot
4071. The upper part of said seat 4070 couples the bottom
of machine body 4072 on the clamping vise having a
recessed ball-shaped structure as a replacement for
11~ .
ring-shaped adjustment structure 4014, and its bottom and
bottom seat 4013 may be joined in a horizontal rotary
adju table ~tructure. Bottom 3eat 4013 has a conve~
ring-ghap~d structure larger than ball-~haped ~eat 4070 to
limit the position of semi-ball-6haped gtructure 4070, and
between them a scale with angular graduations is
provided. The end of ball-shaped central bolt 4016
couples the semi-ball- haped socket ~eat, while its other
end penetrates through bottom seat end ~lot 4071 in the
semi-ball-shaped eat and upper machine body 4072 of the

Similarly the structure ~hown in Fig. 99 may be al~o in
the above-said ~tructural combinations. Fig. 100 is a

bottom seat.
Fig. 100-1 is its front cro~s sectional view.
Besides, in addition to the automation clamping
the drive of the clamping vise i8 often effected by a
guide screw, but in lar~er travels, this usually causes
some trouble to users. Although there are many rapid
drive means available on the market, they are all
unsuitable for strong clamping. An improved design of one
of the major important element of the clamping vise is
described.
Fig~ 101 illustrates a drive method of the
clampin~ vise wherein a revolviny ~orque difference forms
a drive speed before contacting the work piece, which is
3~ greater than the self-shifted drive speed after contacting
the work piece. The bottom of motion jaw 1201 in this
drawing has a transYer~e notch 4044 to accommodate hollow
~ylindrical nut 4041 with inner thread6. The side of said
hollow cylindrical nut ~lo~e to the ~upport ~r~ is to be
inserted with a ring-shaped friction plate 404~ and a
guide screw having two-way threads i~ turned and inserted

therein. ~hen the thruRt needed by the jaw is ~aller
than the ~rictional force between hollow cylindrical nut
4041 and ~he 810t face on the bottom of the motion jaw and
the ring-shaped elastic friction plate, the ~peed of moves
forward or backward according to the speed resulting from
adding the positive and reverse thread pitches. When
motion jaw 1201 contacts a work piece and thus needs an
enlarged push force, h~llow cylindrical nut 4053 set on
the support arm slides and revolves, and ~otion jaw 1201
advances according to the reverse thread pitches of the
coupling of motion jaw 1201.

The above-said guide ~crew 4040 wi~h positive and
reverse threads poses no difficulties in its installation,
i~ fixed jaw 1101 is a knock-down structure, and if fixed
jaw 1101 and the machine seat is integral. To expedite
its installation, coupling handle end 4048 of the guide
screw of both parts has to be smaller than the integral
~tructuxe of the inner diameter of the inner threads on
the support arm, and is installed in from the back fixed
jaw.

Fig. 101-9 is its front cross Bectional view7
Its construction may be that the close handle end
4048 of the guide screw couples the integral stru~ture
such that the diameter of the positive threads on the
support arm is larger and the outer diameter of the
reverse threads to be coupled to the motion jaw is smaller
than that of the inner threads on the support arm~

The above-said two-way bolt may further have a
two-stage structure. Its one ~tage has positive threads
3~ and its other stage has reverse threads at its joining
part. One ~ide is in a projected rod 6tructure 4049, the
