Screwdriver aid

Abstract

The invention provides a screw driver assistor with an angle-square shaped sleeve (1). A first conical gear (3) and a second conical gear (2) in gear transmission connection are arranged along a sleeve cavity; the first conical gear (3) extends to a connecting lug boss (6) with a hexagonal section; the external end of the second conical gear (2) is provided with a connecting lug boss (7) with a hexagonal section as well; axles of the two gears are respectively provided with a first bushing (4) and a second bushing (9). The bottom of a handle of a screw driver (11) is sheathed at one end of the connecting lug boss (6), a screw driver head (12) sheathed on the connecting lug boss (7) is driven through transferring rotating force by gear teeth, and the rotating direction of the screw driver (11) is changed from vertical to horizontal, or from horizontal to vertical, thereby realizing diverting use of the screw driver. Therefore, the performance of the screw driver can be expanded and reinforced. The assistor has the advantages of simple structure, low cost and high efficiency.

Description

technical field [0001] The invention relates to a tool, in particular to a screwdriver auxiliary device for assisting a common industrial screwdriver to start a screw. Background technique [0002] As we all know, traditional screws are usually started, tightened or loosened by using a screwdriver, using its straight or cross-shaped or hexagonal blade to insert vertically into the straight-shaped or cross-shaped or hexagonal slot of the workpiece screw, clockwise Or rotate the operating screw counterclockwise to realize the tightening or loosening of the screw. But this tightening or loosening of the screw must meet a condition, that is, there must be no obstacle between the operator's screwdriver and the workpiece screw, otherwise, the operator cannot start. The known hexagonal right-angle wrench in use can overcome this obstacle and realize the tightening or loosening of the screw, but using this wrench to tighten or loosen the screw requires a large operating space aroun...

AI Technical Summary

Problems solved by technology

But the tightening or loosening of the screw must meet a condition, that is, there must be no obstacle between the operator's screwdriver and the workpiece screw, otherwise, the operator cannot start

The known hexagonal right-angle wrench in use can overcome this obstacle and realize the tightening or loosening of the screw, but using this wrench to tighten or loosen the screw requires a large operating space around the screw. The radius of rotation is at least greater than the width of the operator's palm

If the screw is in a corner, in a narrow place, or where the vertical height is not enough for the length of the screwdriver, it is difficult to solve the problem with a traditional screwdriver alone
