Embodiment Construction

[0022] Referring to accompanying drawing 1~3, this embodiment of screwdriver auxiliary device of the present invention draws material pipe diameter and is ￠ 16mm, and pipe wall thickness is the stainless steel pipe profile of 2mm to make square-shaped sleeve 1, makes sleeve 1 both sides cylinder body perpendicular intersect, There is a first through hole 5 at the bottom of the cylinder at both ends of the cylinder, the diameter of which is ￠10mm. The bottom of the other end tube has a second through hole 8, and the aperture is also ￠10mm. The first bevel gear 3 and the second bevel gear 2 are arranged in transmission connection along the inner cylinder cavity of the sleeve 1 . Wherein the outer end of the wheel shaft of the first bevel gear 3 coaxially extends a connecting boss 6 out of the first through hole 5 of the sleeve 1 . The cross-section of the connecting boss 6 is hexagonal; the outer end of the wheel shaft of the second bevel gear 2 is coaxially provided with a con...

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...
