Description

Torque wrench

This creative department is about a torque wrench.

Press, the general torque wrench is usually available for setting the torque value, so that it can select the appropriate torque setting value according to the assembly and disassembly process of various components. The body of the conventional torque wrench has a driving head at one end, and the body of the torque wrench The other end is equipped with a central push rod to adjust the torque setting value, and an adjustable rotating part is installed at this end. When the rotating part is rotated, the central push rod will be driven by the rotating part to move axially to achieve the adjustment of the torque The torque setting value of the wrench, and then the user can perform the locking operation. However, since the rotation purpose of the rotating part is to drive the central push rod to move, the central push rod has elastic force, so the rotating part needs a lot of effort to rotate when rotating, which makes it difficult to control the rotating part when rotating the rotating part. The rotation speed and the difficulty in knowing the rotation range of the rotating part can often result in users not being able to smoothly adjust to the desired torque value, and there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive torque wrench to solve the above-mentioned problems.

The positioning member is fixed in the body. The torque adjustment assembly includes an abutment member and a spindle, the abutment member can move along the axial direction to adjust the torque setting value, and the spindle is rotatably arranged on the body and is opposite to the abutment member. Screw connection, the mandrel passes through the positioning member to rotate around the axial direction. The jumper assembly includes an elastic member and a plurality of recesses arranged in the circumferential direction. One of the elastic member and the recesses is provided on the mandrel and the other is provided on the positioning member.
