Problems solved by technology

[0002] A wrench is a tool for daily life. The existing manual wrench usually needs to turn the wrench lever to screw the screw. However, due to the small space, the wrench cannot be rotated in a large area, so a wrench that can not turn the wrench lever is needed; Now the electric wrench cannot work without electricity, so a wrench that can work manually or be driven by an electric drive mechanism to be used as an electric wrench is needed

Abstract

The invention discloses an auxiliary type wrench. The auxiliary type wrench comprises a handle mechanism and a rotating mechanism. The rotating mechanism is mounted on the inner portion of the handlemechanism, the handle mechanism comprises a power transmission part, a mode switching part, a pre-tightening force aid part and a holding handle, the power transmission part comprises a driving conical gear and a transmission sleeve which are fixedly connected, when the wrench is used by a worker, work can be better finished through switching of existence of pre-tightening force and non-existenceof the pre-tightening force, a pre-tightening force adjusting ring is rotated to adjust the distance between a ball pushing plate and a spring directly connected with a ball to control the friction force of the ball and a pre-tightening force groove, and the magnitude of the pre-tightening force can be adjusted. Pre-tightening force can be adjusted at any time, a tool can be suitable for work of different pre-tightening forces at the same time, an electric mechanism is connected with a mounting groove, screw electric screwing or unscrewing can be achieved, conversion of manual operation to electric operation can be achieved, and practicability is improved.

Description

technical field [0001] The invention relates to the technical field of tools, in particular to an auxiliary wrench. Background technique [0002] A wrench is a daily tool. The existing manual wrench usually needs to turn the wrench lever to realize screwing. However, due to the small space, the wrench cannot be rotated in a large area, so a wrench that can not turn the wrench lever is needed; Now the electric wrench cannot work without electricity, so a wrench that can work manually or be driven by an electric drive mechanism to be used as an electric wrench is needed. Contents of the invention [0003] In view of the above problems, the present invention provides an auxiliary wrench, which can realize the switching of the mechanism with or without pretightening force by rotating the manual tightening switch. Complete the work; rotate the pre-tightening force adjustment ring to adjust the direct spring distance between the ball push plate and the ball to control the frict...
