随着社会和科技的进步，行业的快速发展，扭力扳手的使用也越来越普遍，扭力扳手的使用也更加精准，如传统的扭力扳手演变为设定式棘轮扭力扳手，数显式的扭力扳手，预置式扭力扳手等等，虽然类别会有所不同，但是他们的原理大致相同

With the progress of society, science and technology and the rapid development of the industry, the use of torque wrench is becoming more and more common, and the use of torque wrench is more accurate. For example, the traditional torque wrench has evolved into set ratchet torque wrench, digital display torque wrench, preset torque wrench, etc. although the categories will be different, their principles are roughly the same

下面分三个步骤去说明：

There are three steps to explain:

1、首先在扭力扳手上设定所需扭距值(由弹簧套在顶杆上向扭距释放关节施压),锁定扭距扳手开始拧紧螺栓,当螺栓达到扭距值后(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.由此来确认达到扭距值的提醒作用.(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)。

1. 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), it will produce the effect of instantaneous disconnection At the moment of disjointed effect, it makes the "click" sound made by the joint knocking on the metal shell of the wrench This confirms the reminder function of reaching the torque value (in fact, it's like the principle that our arm joints are bent at 15 degrees and placed in an iron pipe. After straightening for an instant, we will touch the steel pipe.).

2、扭力扳手所发出的"卡塔"是由本身内部的扭距释放结构产生的,其结构分为压力弹簧,扭距释放关节,扭距顶杆三结构所组成。

2. The "lata" sent by the torque wrench is generated by the internal torque release structure. Its structure is divided into three structures: pressure spring, torque release joint and torque ejector rod.

3、扭力扳手 在发出"卡塔"声后是提示以达到你要求的扭距值了。

3. The torque wrench is prompted to reach the torque value you require after making a "Kata" sound.
