扭剪扳手和扭矩扳手是常見的用于緊固螺栓和螺母的工具，它們的主要區別如下：
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：扭剪扳手主要用來實現扭矩控制，即對螺栓或螺母施加特定的扭矩力，以確保緊固件被正確擰緊。而扭矩扳手除了能夠提供扭矩控制功能外，還具備測量扭矩的功能，可直接讀取施加的扭矩數值。
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. 使用范圍不同：扭剪扳手適用于需要準確控制緊固件扭矩的場合，例如汽車維修、機械設備安裝等。而扭矩扳手不僅適用于扭矩控制，還可用于扭矩測量，適用于更廣泛的領域，包括工業制造、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. 扭力范圍和精度不同：扭剪扳手通常有一定范圍的扭矩調節，可根據需求調整扭矩大小。扭矩扳手通常具備更廣泛的扭矩范圍，且擁有更高的扭矩精度和穩定性。扭矩扳手通常具備標定、校準和記憶等功能，能夠提供更精確和可靠的扭矩控制。
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.
總的來說，扭剪扳手主要用于扭矩控制，而扭矩扳手在扭矩控制的基礎上還具備了扭矩測量的功能。選擇使用哪種工具應根據實際需求和具體應用來決定。
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.
