扭矩扳手又称扭力计、扭力螺钉旋具。它是依据梁的弯曲原理、扭杆的 弯曲原理和螺旋弹簧的压缩原理而设计的，能测量出作用在螺母上的力矩大小。 为了更好的延长扭矩扳手的使用寿命和使用精度，日常使用时需要注意以下几点：
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:
- 在使用扭矩扳手时，要根据工作要求选择适中范围的扭矩扳手，所需扭矩值不得小于扭矩扳手范围的20％，扭矩扳手范围过大不应用于小扭矩工件加固，小范围的扭矩扳手不能超范围使用
-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
使用扭矩扳手时，当听到“咔哒”声时，达到合适的工作扭矩。请勿继续强制扭矩扳手，以免损坏内部机械结构
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
扭矩扳手是精确控制螺栓和螺母紧固力矩的专用工具。请尽可能使用扭矩扳手卸下螺母或进行无扭矩控制的工作，以延长使用寿命
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
严禁将手臂延伸到扭矩扳手的尾部，以免损坏工具 - 根据需要调整所需扭矩，并确认调整机构在启动前处于锁定状态
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
当使用扭矩扳手时，应平衡缓慢加载，不得紧紧按压以避免过载，导致输出扭矩不准确。加载预设扭矩后，停止加载
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，应将其调整到更小扭矩，以使力弹簧充分放松以延长其使用寿命
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
避免潮湿侵入扭矩扳手，防止部件腐蚀
Prevent moisture from invading torque wrench to prevent component corrosion
所选扭矩扳手的套筒尺寸必须与螺栓或螺母的尺寸相同 - 扭力扳手根据手的强度设计，当遇到紧线时，不能使用锤击扳手
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
拉动拉力时应使用扭力扳手，推动扳手易于危险 - 如果长时间不使用，请将刻度调整转矩更小值
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
