扭剪扳手和扭矩扳手是常见的用于紧固螺栓和螺母的工具，它们的主要区别如下：
Torsion wrench and torque wrench are common tools used to tighten bolts and nuts, and their main differences are as follows:
1. 功能不同：扭剪扳手主要用来实现扭矩控制，即对螺栓或螺母施加特定的扭矩力，以确保紧固件被正确拧紧。而扭矩扳手除了能够提供扭矩控制功能外，还具备测量扭矩的功能，可直接读取施加的扭矩数值。
1. Different functions: The torque wrench is mainly used to achieve torque control, that is, to apply specific torque force to bolts or nuts to ensure that the fasteners are correctly tightened. In addition to providing torque control function, torque wrenches also have the function of measuring torque, which can directly read the applied torque value.
2. 使用范围不同：扭剪扳手适用于需要准确控制紧固件扭矩的场合，例如汽车维修、机械设备安装等。而扭矩扳手不仅适用于扭矩控制，还可用于扭矩测量，适用于更广泛的领域，包括工业制造、航空航天等。
2. Different usage ranges: Torsion wrenches are suitable for situations that require accurate control of fastener torque, such as automotive maintenance, mechanical equipment installation, etc. And torque wrenches are not only suitable for torque control, but also for torque measurement, suitable for a wider range of fields, including industrial manufacturing, aerospace, and so on.
3. 扭力范围和精度不同：扭剪扳手通常有一定范围的扭矩调节，可根据需求调整扭矩大小。扭矩扳手通常具备更广泛的扭矩范围，且拥有更高的扭矩精度和稳定性。扭矩扳手通常具备标定、校准和记忆等功能，能够提供更精确和可靠的扭矩控制。
3. Different torque range and accuracy: Torsion wrenches usually have a certain range of torque adjustment, and the torque size can be adjusted according to needs. Torque wrenches typically have a wider torque range and higher torque accuracy and stability. Torque wrenches typically have functions such as calibration, calibration, and memory, providing more accurate and reliable torque control.
总的来说，扭剪扳手主要用于扭矩控制，而扭矩扳手在扭矩控制的基础上还具备了扭矩测量的功能。选择使用哪种工具应根据实际需求和具体应用来决定。
Overall, torque wrenches are mainly used for torque control, and in addition to torque control, torque wrenches also have the function of torque measurement. The choice of which tool to use should be based on actual needs and specific applications.
