Why does the torque wrench produce chattering? The principle is very simple. Let's explore it together

　　力矩扳手的原理(力矩扳手)产生的声音是很简单的cata，可以分为以下几个步骤来理解:

　　The principle of torque wrench (torque wrench) is to produce a simple cat a, which can be understood in the following steps:

　　1. 转矩扳手表示您需要的转矩值在“cata”声后到达;

　　1. The torque wrench indicates that the torque value you need reaches after the "cata" sound;

　　2. 扭矩扳手产生的“cata”是由内部扭矩释放机构产生的，内部扭矩释放机构由压力弹簧、扭矩释放接头和扭矩喷射器三部分组成。

　　2. "Cata" produced by torque wrench is produced by internal torque release mechanism, which consists of pressure spring, torque release joint and torque injector.

　　3.，在扭矩扳手上设置所需的扭矩值(弹射杆上设置弹簧，按下扭矩释放接头)，锁紧扭矩扳手，拧紧螺栓。当螺栓达到扭矩值时(当施加的扭矩大于弹簧压力时)，立即断开。在脱臼的瞬间，关节受到撞击，扳手的金属外壳发出“卡塔”的声音。这是为了确认力矩值的警示作用(其实就像我们的手臂关节在15度弯曲的铁管中立即伸直就会击中钢管的原理)。

　　3. First, set the required torque value on the torque wrench (set the spring on the ejection rod and press the torque release joint), lock the torque wrench and tighten the bolts. When the bolt reaches the torque value (when the applied torque is greater than the spring pressure), disconnect immediately. At the moment of dislocation, the joint is hit, and the metal shell of the wrench makes a "Kata" sound. This is to confirm the warning effect of the torque value (actually, it's just like the principle that our arm joint will hit the steel pipe if it straightens immediately in the 15 degree bending iron pipe).

　　上面说的是更常用的手动扭矩扳手，除了电动扭矩扳手、气动扭矩扳手等。

　　Above said is the most commonly used manual torque wrench, in addition to electric torque wrench, pneumatic torque wrench, etc.
