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.

在扭力扳手上設(shè)定所需扭矩值（由彈簧套在頂桿上向扭矩釋放關(guān)節(jié)施壓），鎖定扭力扳手，開(kāi)始擰緊螺栓。當(dāng)螺栓達(dá)到扭矩值（當(dāng)使用扭力大于彈簧的壓力）后，會(huì)產(chǎn)生瞬間脫節(jié)的效應(yīng)。

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.

在產(chǎn)生脫節(jié)效應(yīng)的瞬間發(fā)出關(guān)節(jié)敲擊，扳手金屬外殼所發(fā)出的“卡塔”聲。由此來(lái)確認(rèn)達(dá)到扭矩值的提醒作用（其實(shí)就像我們手臂關(guān)節(jié)成15度彎曲放在鐵管里瞬間申直后會(huì)碰到鋼管的原理一樣）。

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).
