Torsion adjusting and locking mechanism of torsion tool

Abstract

The invention discloses a torsion adjusting and locking mechanism of a torsion tool, comprising an operation rod body, a shaft lever and a turning sleeve, wherein the end part of the operation rod body is provided with a tool head for operating a working object; the operation rod body is internally provided with a strain gauge for detecting torsion; the operation rod body is also provided with a strain spring for adjusting the torsion behind the strain gauge; the tail end of the operation rod body is provided with a shaft groove the periphery of which is provided with a series of positioning teeth sockets; the shaft lever is pivoted in the center of the operation rod body and is provided with an adjustment block capable of propelling the strain spring to compress; one section of the shaft lever penetrating in the shaft groove of the operation rod body is provided with a grinding tooth section; and the turning sleeve is provided with a shaft part pivoted on the shaft groove, is provided with at least one positioning tooth block capable of being selectively embedded and clamped in different positioning teeth sockets of a grip shaft groove at the periphery of the shaft part, and is provided with a grinding tooth hole corresponding to the grinding tooth section of the shaft lever. The mechanism can accurately adjust to the required torsion value and lock rapidly, thus enhancing convenience for operating the torsion tool.

Description

technical field [0001] The invention belongs to the technical field of adjusting torque of a hand tool, and specifically refers to an accurately adjusted and quickly locked torque adjusting and locking mechanism, so as to improve the operation convenience of adjusting the torque value of a torque tool. Background technique [0002] Torque wrench is equipped with a strain gauge connected to the tool head in the body of the operating rod. Using the function of the strain gauge, the output torque of the wrench can be detected in real time, so as to avoid the locking of the screw or the collapse of the tooth due to improper operation force. , so that an appropriate locking effect can be obtained. In order to increase the convenience of use of the existing torque wrench, a torque setting structure is further provided on the operating rod body, and the torque setting structure is used to actuate a strain spring supported on the rear of the strain gauge, which is used when the torq...
