Document Type and Number:
WIPO Patent Application WO/2016/176817
Kind Code:
A1
Abstract:
Disclosed is a wrench, which is used for wrenching a workpiece and comprises a one-way transmission mechanism. The one-way transmission mechanism comprises rollers (112), a first part (110) and a second part (111) at least partially sheathed in the first part, wherein the first part (110) is fixedly provided in a wrenching part of the wrench, and the second part (111) is used for cooperating with the workpiece. The directions of the moments of rotation from the wrenching part are a first direction and a second direction of a rotation shaft along the first part (110); with regard to either the moment of rotation of the first direction and the moment of rotation of the second direction, the second part (111) is stationary with regard to the first part (110) so as to output the moment of rotation to the workpiece; and with regard to the other one, the second part (111) rotates with regard to the first part (110) but does not transmit the moment of rotation to the workpiece. The torque of the one-way transmission mechanism can fulfil the requirements of using a wrench, and at the same time, the one-way transmission mechanism generates no noise during use and has the characteristic of bearing abrasion resistance.
