扭剪扳手（Torque Wrench）和扭矩扳手（Torque Wrench）是两种常见的手动工具，用于控制螺栓或螺母的紧固扭矩。它们在使用方法和功能上有一些区别：
Torque Wrench and Torque Wrench are two common hand tools used to control the tightening torque of bolts or nuts. They have some differences in usage and functionality:
使用方法：
Usage:
扭剪扳手：扭剪扳手通常用于控制螺栓或螺母的预紧力。它可以通过调节扳手上的刻度或设定预定的扭矩值来达到所需的预紧力，并在达到设定扭矩时发出可听见的“咔嗒”声或产生其他指示信号。
Torsion wrench: Torsion wrench is usually used to control the pre tightening force of bolts or nuts. It can achieve the required pre tightening force by adjusting the scale on the wrench or setting a predetermined torque value, and emit an audible "click" sound or other indicating signals when the set torque is reached.
扭矩扳手：扭矩扳手用于准确控制螺栓或螺母的扭矩。它通常具有一个可调节的扭矩设置装置，可以根据具体要求设定所需的扭矩值。当达到设定扭矩时，扳手会发出可听见的“咔嗒”声或通过其他指示方式表明已经达到了预定扭矩。
Torque wrench: A torque wrench is used to accurately control the torque of a bolt or nut. It usually has an adjustable torque setting device that can set the required torque value according to specific requirements. When the set torque is reached, the wrench will emit an audible "click" sound or indicate through other means that the predetermined torque has been reached.
适用范围：
Applicable scope:
扭剪扳手：扭剪扳手主要用于需要对螺栓进行预紧的应用，如汽车轮胎安装、机械设备组装等。它适用于对螺栓施加一定的初始紧固力，并确保螺栓达到所需的拉力。
Torsion wrench: Torsion wrench is mainly used for applications that require pre tightening of bolts, such as car tire installation, mechanical equipment assembly, etc. It is suitable for applying a certain initial tightening force to the bolt and ensuring that the bolt reaches the required tension.
扭矩扳手：扭矩扳手适用于需要准确控制螺栓或螺母的扭矩的应用，如航空航天、汽车引擎装配、工业设备等。它可以确保螺栓或螺母按照指定的扭矩值进行紧固，以避免过度紧固或松动。
Torque wrench: Torque wrench is suitable for applications that require accurate control of the torque of bolts or nuts, such as aerospace, automotive engine assembly, industrial equipment, etc. It can ensure that bolts or nuts are tightened according to the specified torque value to avoid excessive tightening or loosening.
精确度和校准：
Accuracy and calibration:
扭剪扳手：扭剪扳手通常具有较低的精确度，其误差范围在正常使用范围内。一些扭剪扳手可能需要定期校准以保持其准确性。
Torsion wrench: Torsion wrench usually has low accuracy, and its error range is within the normal range of use. Some shear wrenches may require regular calibration to maintain their accuracy.
扭矩扳手：扭矩扳手通常具有较高的精确度，并且经过了精密的校准。高质量的扭矩扳手具有更窄的误差范围，并且可能需要更频繁的校准来确保其准确性。
Torque wrench: Torque wrenches typically have high accuracy and have undergone precise calibration. High quality torque wrenches have a narrower error range and may require more frequent calibration to ensure their accuracy.
