Abstract

The invention discloses a self force augmentation type bidirectional wrench and an operating method thereof. The self force augmentation type bidirectional wrench comprises a handle, a force-augmentation reversing part, a reversing switch, a shifting lever and a sleeve. The force-augmentation reversing part comprises an input shaft, an intermediate shaft, a reversing shaft, an output shaft, an input gear, a transmission gear, a forward gear, a reverse gear, an output gear, a spring and a steel ball. The output gear can be selected to be engaged with the forward gear or the reverse gear through the reversing switch so that the output shaft and the sleeve can rotate in the same direction as the handle or rotate in the direction opposite to the rotating direction of the handle, and the force moment of the handle can be amplified through two-stage gear transmission. The self force augmentation type bidirectional wrench is simple in structure, convenient to operate, capable of screwing and unscrewing screws in two directions, and capable of saving strength.

Description

technical field [0001] The invention relates to the convenience and labor saving of the wrench, in particular to a self-energizing two-way wrench which continuously outputs the same torque in two directions and can increase the output torque when tightening or loosening a screw and its working method. Background technique [0002] In the process of using a general wrench, it is often only possible to apply force in one direction, and the movement of the hand in the direction of rotation is limited and cannot be sustained. After reaching the limit in one direction, it is often necessary to pick up the wrench again or reverse the wrench. Rotating to the idle stroke reduces the working efficiency of tightening screws or loosening screws. [0003] In order to solve the above problems, U.S. Patent No. 5,931,062 discloses a conversion device, which has a main shaft and a driving element, and a one-way clutch is installed between the driving element and the main shaft. Through the ...
