扭力扳手也称扭矩扳手或力矩扳手。它发出卡塔声音的原理很简单。扭力扳手在发出“卡塔”声后是提示已达到你要求的扭矩值了；扭力扳手所发出的“卡塔”是由本身内部的扭矩释放结构产生的，其结构分为压力弹簧、扭矩释放关节、扭矩顶杆三结构所组成。
Torque wrench is also called torque wrench or torque wrench. The principle of its Kata sound is very simple. The torque wrench indicates that the torque value you require has been reached after making a "Kata" sound; The "lata" issued by the torque wrench is generated by its own internal torque release structure, which is divided into three structures: pressure spring, torque release joint and torque ejector rod.
首先在扭力扳手上设定所需扭矩值（由弹簧套在顶杆上向扭矩释放关节施压），锁定扭力扳手，开始拧紧螺栓。当螺栓达到扭矩值（当使用扭力大于弹簧的压力）后，会产生瞬间脱节的效应。
First, set the required torque value on the torque wrench (the spring is sleeved on the ejector rod to press the torque release joint), lock the torque wrench and start tightening the bolts. When the bolt reaches the torque value (when the torque used is greater than the pressure of the spring), it will produce the effect of instantaneous disconnection.
在产生脱节效应的瞬间发出关节敲击，扳手金属外壳所发出的“卡塔”声。由此来确认达到扭矩值的提醒作用（其实就像我们手臂关节成15度弯曲放在铁管里瞬间申直后会碰到钢管的原理一样）。
At the moment of disjointed effect, the joint knock and the "Kata" sound made by the metal shell of the wrench are sent out. So as to confirm the reminder effect of reaching the torque value (in fact, it is the same as the principle that our arm joints will touch the steel pipe after being bent at 15 degrees and placed in the iron pipe for instant straightening).
