扭矩扳手又稱扭力計、扭力螺釘旋具。它是依據梁的彎曲原理、扭桿的 彎曲原理和螺旋彈簧的壓縮原理而設計的，能測量出作用在螺母上的力矩大小。 為了更好的延長扭矩扳手的使用壽命和使用精度，日常使用時需要注意以下幾點：
Torque wrench is also known as torque meter, torque screw driver. It is designed according to the bending principle of beam, the bending principle of torsion bar and the compression principle of spiral spring. It can measure the torque acting on the nut. In order to better extend the service life and accuracy of torque wrench, the following points should be paid attention to in daily use:
- 在使用扭矩扳手時，要根據工作要求選擇適中范圍的扭矩扳手，所需扭矩值不得小于扭矩扳手范圍的20％，扭矩扳手范圍過大不應用于小扭矩工件加固，小范圍的扭矩扳手不能超范圍使用
-When using the torque wrench, we should first select the appropriate range of torque wrench according to the work requirements. The required torque value should not be less than 20% of the range of torque wrench. If the range of torque wrench is too large, it should not be used for the reinforcement of small torque workpieces, and the small range of torque wrench should not be used beyond the range
使用扭矩扳手時，當聽到“咔噠”聲時，達到合適的工作扭矩。請勿繼續(xù)強制扭矩扳手，以免損壞內部機械結構
When using the torque wrench, when the "click" sound is heard, the appropriate working torque is reached. Do not continue to force the torque wrench to avoid damaging the internal mechanical structure
扭矩扳手是精確控制螺栓和螺母緊固力矩的專用工具。請盡可能使用扭矩扳手卸下螺母或進行無扭矩控制的工作，以延長使用壽命
Torque wrench is a special tool to control the tightening torque of bolt and nut accurately. Please use the torque wrench to remove the nut or work without torque control as far as possible to extend the service life
嚴禁將手臂延伸到扭矩扳手的尾部，以免損壞工具 - 根據需要調整所需扭矩，并確認調整機構在啟動前處于鎖定狀態(tài)
Never extend the arm to the end of the torque wrench to avoid damaging the tool - adjust the required torque as needed and make sure that the adjusting mechanism is locked before starting
當使用扭矩扳手時，應平衡緩慢加載，不得緊緊按壓以避免過載，導致輸出扭矩不準確。加載預設扭矩后，停止加載
When using the torque wrench, the load should be balanced and slow, and should not be pressed tightly to avoid overload, resulting in inaccurate output torque. After loading the preset torque, stop loading
使用扭矩扳手后，應將其調整到更小扭矩，以使力彈簧充分放松以延長其使用壽命
After using the torque wrench, it should be adjusted to the minimum torque to make the force spring fully relax and extend its service life
避免潮濕侵入扭矩扳手，防止部件腐蝕
Prevent moisture from invading torque wrench to prevent component corrosion
所選扭矩扳手的套筒尺寸必須與螺栓或螺母的尺寸相同 - 扭力扳手根據手的強度設計，當遇到緊線時，不能使用錘擊扳手
The socket size of the selected torque wrench must be the same as that of the bolt or nut - the torque wrench is designed according to the strength of the hand, and the hammer wrench cannot be used when the thread is tight
拉動拉力時應使用扭力扳手，推動扳手易于危險 - 如果長時間不使用，請將刻度調整轉矩更小值
Torque wrench should be used when pulling the pulling force. Pushing the wrench is easy to be dangerous - if it is not used for a long time, please adjust the scale to the minimum torque
