So far, there are still many users who do not understand how the torque wrench issues the sound of Kata. Today, Shanghai Shi Heng Xiao Bian explained to everyone the principle of issuing Kata sound under the torque wrench.

Torque Wrench Profile

In fact, it is very simple, mainly divided into the following steps to understand:

1. After the torque wrench issues a "Kata" sound, it indicates that the torque value you have reached has been reached;

2. The “Kata” issued by a torque wrench is generated by its own internal torque release structure. Its structure is divided into three structures: a compression spring, a torque release joint and a torque jack.

3. First, set the required torque value on the torque wrench (pressed by the spring sleeve on the top rod to the torque release joint), lock the torque wrench, and start tightening the bolt. When the bolt reaches the torque value (when the torque is greater than the spring pressure), there will be a momentary disconnection effect. At the moment of a disjointed effect, joint knocks are issued and the "Kata" sound from the metal casing of the wrench. From this, we can confirm the reminding effect of reaching the torque value (actually the same principle as when we put the 15 degree bend of the arm joint into the iron pipe and immediately hit the steel pipe).

After listening to the above steps to explain is not understand it, if you do not understand, you are welcome to inquire oh.
