扭力扳手也稱扭矩扳手或力矩扳手。它發出卡塔聲音的原理很簡單。扭力扳手在發出“卡塔”聲后是提示已達到你要求的扭矩值了；扭力扳手所發出的“卡塔”是由本身內部的扭矩釋放結構產生的，其結構分為壓力彈簧、扭矩釋放關節、扭矩頂桿三結構所組成。
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.
在扭力扳手上設定所需扭矩值（由彈簧套在頂桿上向扭矩釋放關節施壓），鎖定扭力扳手，開始擰緊螺栓。當螺栓達到扭矩值（當使用扭力大于彈簧的壓力）后，會產生瞬間脫節的效應。
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.
在產生脫節效應的瞬間發出關節敲擊，扳手金屬外殼所發出的“卡塔”聲。由此來確認達到扭矩值的提醒作用（其實就像我們手臂關節成15度彎曲放在鐵管里瞬間申直后會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).
