Embodiment Construction

[0035] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0036] Such as figure 1 with figure 2 As shown, the present invention discloses a self-energizing two-way wrench, which includes a handle 1, a reversing part 2, a reversing switch 7, a shift lever 8 and a sleeve 3;

[0037] The booster reversing part 2 includes an input shaft 5, an input gear 4, an intermediate shaft 14, a transmission gear 15, a same direction gear 13, a reversing shaft 11, a reverse gear 12, an output shaft 6, an output gear 10, and a spring 16. And steel ball 17;

[0038] One end of the input shaft 5 is fixedly connected with the handle 1; the intermediate shaft 14, the reversing shaft 11, and the output shaft 6 are all parallel to the input shaft 5;

[0039] The input gear 4 is fixed on the input shaft 5; the same direction gear 13 and the transmission gear 15 are fixed on the intermediate shaft 14; the reverse gear 12 i...

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 problems of simplicity and labor saving when using a wrench, in particular to a self-amplifying two-way wrench and a working method thereof that continuously output the same torque in both directions and can increase the output torque when tightening or loosening a screw. 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 empty stroke reduces the efficiency of tightening or loosening screws. [0003] In order to solve the above problems, US Patent No. 5,931,062 discloses a conversion device. A one-way clutch is installed between the main shaft of the device and the driving element, and the driving element and the main shaft. Throu...
