Description

torque wrench

This creation is about a torque wrench.

Press, the general torque wrench is usually used to set the torque value, so that it can select the appropriate torque setting value according to the assembly and disassembly process of various components. One end of the body of a conventional torque wrench is provided with a driving head, and the other end of the body of the torque wrench is provided with a central push rod, a locking device and a holding part. The central push rod is used to adjust the torque setting value, and the locking The device can optionally be used to lock or release the central push rod, so that the central push rod cannot move to adjust the torque setting value, or unlocked so that the central push rod can adjust the torque setting value. However, when the conventional torque wrench is used to hold the holding portion, the hand is easy to touch the locking device, resulting in inadvertent adjustment to the adjustment torque setting value during operation and use, resulting in errors. The locking device interferes and cannot get any closer to the drive head.

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

The main purpose of the present invention is to provide a torque wrench, which can be closer to a driving head when the hand is held in use, and is not easy to touch a torque adjustment component when holding a grip for operation, which can ensure that the operation process is not easy. The locked state of a rotating part will be released arbitrarily.

In order to achieve the above object, the present invention provides a torque wrench, comprising: a main body defining an axial direction; a driving portion disposed at one end of the main body, when the driving portion receives a torque greater than a torque setting value, it will generate Idling phenomenon; a grip sleeve, which is sleeved on the main body; a torque adjusting component, which can move along the axial direction to adjust the torque setting value; , the outer periphery of the rotating member is provided with a radially protruding limiting portion; a locking unit, which is arranged between the grip sleeve and the limiting portion in the axial direction, can be located at a first position and a When the locking unit is located at the first position, the rotating member cannot rotate relative to the body; when the locking unit is located at the second position, the rotating member can rotate relative to the body.
