Torsion wrench is an essential tool in the field of modern mechanical maintenance, which can help people complete various bolt and nut tightening tasks quickly and easily. This article will provide a detailed introduction to this practical tool from the aspects of its properties, structure, usage methods, and precautions.

屬性：扭剪扳手是一種可以自動校準扭矩值的扳手，在不同的需求下可調節(jié)扭矩大小，大扭力值可達到1000Nm以上。正因為有了扭剪扳手的存在，人們對于使用的扭矩值能夠達到更加精準，從而避免了由于過松或者過緊所導致的問題。

Attribute: Torsion wrench is a type of wrench that can automatically calibrate torque values. It can adjust the torque size according to different needs, and the large torque value can reach over 1000Nm. Thanks to the existence of a torsion wrench, people can achieve more accurate torque values, thereby avoiding safety issues caused by being too loose or too tight.

結構：扭剪扳手主要由兩個部分組成，即彎曲杠桿和卡口頭。彎曲杠桿的把手比較長，手握起來比較舒適，卡口頭則可以安裝不同尺寸的指向頭部，在維修中更加方便快捷。同時，扭剪扳手的內部機構還包括了可調節(jié)的彈簧、齒輪以及其他配件，保證扳手的功能使用更加穩(wěn)定。

Structure: The torsion shear wrench mainly consists of two parts, namely a bending lever and a clamp mouth. The handle of the curved lever is relatively long, making it comfortable to hold. The bayonet head can be installed with different sizes pointing towards the head, making maintenance more convenient and efficient. At the same time, the internal mechanism of the torsion wrench also includes adjustable springs, gears, and other accessories, ensuring a more stable use of the wrench's function.

使用方法：需要根據任務中的具體需求選擇不同的扳頭尺寸，并且將其安裝到扳手頭部。接下來，操作人員需要通過手動旋轉扳手來調節(jié)扭矩值，確保每次進行固緊時都遵循著正確的扭力強度。在完成維修任務后，用戶則可以通過反向旋轉操作來解除所固定的螺母或螺栓。

Usage: Firstly, different wrench sizes need to be selected based on the specific requirements in the task, and installed on the wrench head. Next, the operator needs to manually rotate the wrench to adjust the torque value, ensuring that the correct torque strength is followed every time tightening is carried out. After completing the maintenance task, the user can release the fixed nut or bolt by reverse rotation operation.

注意事項：在使用扭剪扳手之前一定要對自己需要維修的零部件有一個大致的了解，以便于選擇合適的扭剪扳手和正確地調節(jié)所需扭矩大小。此外，還需要注意選擇高質量的扭剪扳手并且定期進行檢測，以確保自身維修。

Attention: Before using a torque wrench, it is important to have a general understanding of the components that need to be repaired, in order to select the appropriate torque wrench and adjust the required torque correctly. In addition, it is also necessary to pay attention to selecting high-quality torsion shear wrenches and conducting regular inspections to ensure self maintenance safety.

小結：扭剪扳手的出現，提高了機械維修的效率，同時也更好地保障了操作人員的維修。學會正確地使用扭剪扳手，對于機械從業(yè)者是一項非常必要的技能和知識。

Summary: The emergence of a torsion wrench has improved the efficiency of mechanical maintenance and also better ensured the maintenance safety of operators. Learning to use a torsion wrench correctly is a necessary skill and knowledge for mechanical practitioners.
