Torque wrench

This creation is about a torque wrench.

Wrench is an indispensable tool in the process of installing mechanical devices and equipment. Nowadays, the torque wrench on the market can adjust the torque value output, so as to prevent the user from being damaged when the parts are locked due to improper force, slippery teeth and broken screws.

The torque wrench of the prior art has a scale printed on the wrench body. When adjusting the torque value of the wrench, the current torque value can be judged through the scale to accurately adjust the torque of the wrench to a predetermined value. However, when using a torque wrench, the user always inadvertently holds and touches the scale, and even attaches oil to the scale, causing the scale of the torque wrench to peel off after a long period of use, and there is an unclear problem. The operation cannot be accurately determined by the current torque value.

In addition, the torque wrench of the prior art adjusts the torque value by moving a set of grips provided on the wrench body relative to the scale, and aligning the scale with the tubular edge of the grip to provide the user with the current judgment. Torque value. However, during the adjustment process, the grip moves relative to the wrench body, causing the length of the operating force arm to change, and there is operational inconvenience.

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

The main purpose of this creation is to provide a torque wrench that maintains the integrity of the scale.

In order to achieve the above object, the present invention provides a torque wrench, comprising: a wrench body, comprising a tube body and a driving head disposed at one end of the tube body; a torque adjustment mechanism is disposed on the tube body and adjustably abutting a driving sleeve; a kit is sleeved on the tube body, the kit is provided with at least one see-through window; at least one scale is disposed between the tube body and the sleeve, the at least one scale corresponding to at least one see-through window; wherein Adjusting the torque adjustment mechanism can change the relative position of the at least one scale to the at least one see-through window.
