screwdriver aids

Abstract

A screwdriver assisting tool comprises a connecting pipe and a vertical fixing plate, wherein a fixing groove is formed in the top of the fixing plate, the width of the fixing groove is greater than the diameter of the small-diameter end of a screw, the width of the fixing groove is smaller than the diameter of the large-diameter end of the screw, a connecting plate is arranged between the bottomof the connecting pipe and the bottom of the fixing plate, and the length of the connecting plate is greater than the thickness of the large-diameter end of the screw. Before the screw is installed, the small-diameter end of the screw penetrates through the fixing groove, so that the large-diameter end of the screw is located on the side of the fixing plate, and a screwdriver rod of the screwdriver penetrates through the connecting pipe, so that the large-diameter end of the screw is matched with the fixing plate and abuts against the fixing plate through the screwdriver. Accordingly, the screw cannot drop, after the screw is screwed into a preformed hole, the screwdriver is loosened firstly, the fixing plate separates from the screw along the fixing groove, then the screw is tightened byusing the screwdriver, the screw does not drop in the whole installing process, and the phenomenon is prevented that the screw drops into an area which cannot be touched by a user to cause short circuit, and accordingly personal safety and device safety are harmed.

Description

technical field [0001] The present invention relates to screw installation aids, in particular to screwdriver aids. Background technique [0002] The terminal block is an insulating part that carries multiple or multiple sets of mutually insulated terminal assemblies and is used to fix the support. The function of the terminal block is to connect the lines of the on-screen equipment and the off-screen equipment, and play the role of signal transmission. The screw holes on the terminal block are often in some long and narrow areas, and it is difficult for human hands to reach in for operation. When installing the screws, it is difficult to put the screws into the corresponding screw holes. The traditional solution is to use a magnetic screwdriver. The screw is sucked on the cutter head, and this method is only suitable for iron screws, not for aluminum, copper screws and stainless steel screws. Once the screw falls into a narrow and long area, it will be difficult to take it...

AI Technical Summary

Problems solved by technology

The screw holes on the terminal block are often in some long and narrow areas, and it is difficult for human hands to reach in for operation. When installing the screws, it is difficult to put the screws into the corresponding screw holes. The traditional solution is to use a magnetic screwdriver. The screw is sucked on the cutter head, and this method is only suitable for iron screws, not for aluminum, copper screws and stainless steel screws. Once the screw falls into a narrow and long area, it will be difficult to take it out, and the dropped screw may even cause a short circuit. Danger to personal and equipment safety
