A problem occurs when using stamped wing nuts for example for the assembly and disassembly of carports and any other structures secured by stamped wing nuts. There is no tool that could be installed on a drill or other tool holder to screw or unscrew stamped wing nuts onto or off of bolts that hold the pieces together. One must screw them on by hand which could compromise the strength of the stamped wing nuts or damage them, thereby posing a risk of the object detaching upon movement. In the present invention the tool facilitates the screwing and unscrewing nuts of stamped wing nuts by perfectly adjusting to the shape of the stamped wing nut thus reducing thereby reducing working time. It can be adapted to different types of drill stems and to different sizes of stamped wing nuts.
Lors de l'utilisation d'écrous papillon vides par exemple, pour le montage et
le
démontage des abris d'auto ainsi que tout objet fixé par des écrous papillon
vides, un
problème survient. Il n'existe aucun outil pouvant s'installer sur une
perceuse ou tout
autre porte outil pour visser ou dévisser des écrous papillon vides sur les
boulons
retenant les pièces ensemble, nous devons donc les visser à la main ce qui
rend moins
efficace la solidité des écrous papillon vides, ou endommage les écrous
papillon vides
causant ainsi des risques de démembrement de l'objet lors de mouvement. Dans
la
présente invention l'outil facilite le vissage et le dévissage des écrous
papillon vides
en s'ajustant parfaitement à la forme des écrous papillon vides diminuant
ainsi le
temps de travail. Elle peut être adaptée aux différents formats de la tige de
la
perceuse ainsi qu'aux différents formats des écrous vides.
