扭矩扳手产生的“卡塔”是由其内部扭矩释放结构产生的，扭矩释放结构由压力弹簧、扭矩释放接头和扭矩顶杆三种结构组成。首先，在扭矩扳手上设定需要的扭矩值(弹簧套在顶杆上压下扭矩释放接头)，锁紧扭矩扳手，开始拧紧螺栓。当螺栓达到扭矩值时(当扭矩大于弹簧的压力时)，就会产生瞬间断开的效果。在断开效应的瞬间，接头被敲击，扳手的金属外壳发出“粘”的声音。
The "jam" produced by torque wrench is produced by its internal torque release structure, which is composed of pressure spring, torque release joint and torque ejector. First, set the required torque value on the torque wrench (the spring sleeve presses down the torque release joint on the ejector), lock the torque wrench and start to tighten the bolt. When the bolt reaches the torque value (when the torque is greater than the spring pressure), it will produce the effect of instantaneous disconnection. At the moment of disconnection effect, the joint is knocked and the metal shell of the wrench makes a "sticky" sound.
从而确认达到扭矩值的提醒功能(其实就像我们的手臂关节弯成15度放在铁管里，瞬间调直后就会碰到钢管的原理一样卡式扳手
So as to confirm the reminder function of reaching the torque value (in fact, it's just like the principle that our arm joint is bent to 15 degrees and placed in the iron pipe, and it will touch the steel pipe after instant straightening)
扭力扳手也叫扭矩扳手。扭矩是力和距离的乘积。拧紧螺钉、螺栓和螺母等螺纹紧固件时，有必要控制施加的扭矩，以确保螺纹拧紧，并且螺纹不会因扭矩过大而损坏，因此使用扭矩扳手进行操作。
Torque wrench is also called torque wrench. Torque is the product of force and distance. When tightening screw, bolt, nut and other threaded fasteners, it is necessary to control the applied torque to ensure that the thread is tightened, and the thread will not be damaged due to excessive torque, so the torque wrench is used for operation.
首先，设定所需扭矩值的上限。当施加的扭矩达到设定值时，扳手会发出“卡住”的声音，或者扳手的接头会弯曲一点点角度，这意味着它已经拧紧，不需要额外的力。
First, set the upper limit of the required torque value. When the applied torque reaches the set value, the wrench will make a "stuck" sound, or the wrench joint will bend a little bit, which means that it has been tightened and no additional force is required.
将套筒安装在螺栓头或螺母上。向右转动扭力扳手进行紧固。
Install the sleeve on the bolt head or nut. Turn the torque wrench to the right to tighten.

听到“咔嗒”声后，紧固完成。插入套管
After hearing the "click" sound, the fastening is completed. Insert the sleeve
使用扭矩扳手的注意事项
Precautions for using torque wrench
施加扭矩时，将手放在扭矩扳手手柄的中间刻度线上。方头与套筒和螺母连接牢固。
When applying torque, put your hand on the middle scale line of the torque wrench handle. The square head is firmly connected with the sleeve and nut.
力只能按已知扳手标注的方向施加，施力方向应在正负15度以内。
The force can only be applied in the direction marked by the known wrench, and the direction of application should be within plus or minus 15 degrees.
