扭力扳手又称扭力计、扭力螺钉旋具。它是依据梁的弯曲原理、扭杆的弯曲原理和螺旋弹簧的压缩原理而设计的，能测量出作用在螺母上的力矩大小。
Torque wrench is also called torque meter and torque screw driver. It is designed according to the bending principle of the beam, the bending principle of the torsion bar and the compression principle of the coil spring, and can measure the torque acting on the nut.
扭力扳手有一根长的弹性杆，其一端装着手柄，另一端装有方头或六角头，在方头或六角头上套装一个可换的套筒，用钢珠卡住。在顶端上还装有一个长指针。刻度板固定在柄座上，每格刻度值为1N（或kg/m）。 使用前，先将安装在扳手上的指示器调整到所需的力矩，然后扳动扳手，当达到该预定力矩时，指示器上的指针就会向销轴一方转动，后指针与销轴碰撞，通过音箱信号或传感信号告知操作者。
The torque wrench has a long elastic rod, one end of which is equipped with a handle, and the other end is equipped with a square head or a hexagon head. A replaceable sleeve is set on the square head or the hexagon head, and is clamped with steel balls. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value of each grid is 1n (or kg / M). Before use, first adjust the indicator installed on the wrench to the required torque, and then pull the wrench. When the predetermined torque is reached, the pointer on the indicator will rotate toward the pin shaft, and then the pointer will collide with the pin shaft, and the operator will be informed by the speaker signal or sensing signal.
扭矩扳手（扭力扳手）发出卡塔声音的原理很简单，可以分为以下几个步骤去理解：
The principle that the torque wrench (torque wrench) emits the sound of jamming is very simple and can be understood in the following steps:
1、扭矩扳手在发出“卡塔”声后是提示已达到你要求的扭矩值了；
1. When the torque wrench makes a "click" sound, it indicates that the torque value you require has been reached;
2、扭矩扳手所发出的“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.
2. The "Kata" generated by the torque wrench is generated by the internal torque release structure, which is composed of pressure spring, torque release joint and torque ejector rod
3、在扭矩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），锁定扭矩扳手，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。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(其实就象我们手臂关节成15度弯曲放在铁管里瞬间申直后会碰到钢管的原理一样）。
3. First, set the required torque value on the torque wrench (press the torque release joint by the spring sleeve on the ejector rod), lock the torque wrench and start tightening the bolt. When the bolt reaches the torque value (when the torque is greater than the pressure of the spring), the effect of instantaneous disconnection will occur. At the moment when the disconnection effect is generated, the joint knock and the "cata" sound from the metal shell of the wrench are emitted. So as to confirm the reminding effect of reaching the torque value (in fact, it is the same as the principle that our arm joint is bent at 15 degrees and placed in the iron pipe for instant straightening, and then it will touch the steel pipe).
