CA 02406671 2002-10-04
In operation, the user may operate the bent bar S26 to move the safety
pin 524, so that the safety pin 524 may be inserted into and detached from the
insertion hole 513 of the insertion tenon 512 of the boot 51 by the elastic
action
of the spring 525. Thus, the base 52 may be mounted on or detached from the
bottom of the boot 51 according to the user's requirements.
However, when the base 52 is mounted on the bottom of the boot 51,
the safety pin 524 cannot align with the insertion hole 513 of the insertion
tenon 512 of the boot 51 easily, so that the base 52 cannot be mounted on the
