在碳纤维件和轻质件的安装过程中，螺钉的拧紧程度和均匀度对扭矩扳手的选择在使用寿命中尤为重要，衡量这两个因素的指标是安装过程中的扭矩。在正确的扭矩范围内，既能夹紧零件，又能防止滑齿或损坏。
In the installation process of carbon fiber and light weight parts, the tightening degree and uniformity of screw are particularly important for the selection of torque wrench in service life. The index to measure these two factors is the torque in the installation process. Within the correct torque range, it can not only clamp parts, but also prevent sliding teeth or damage.
此外，在机械行业中，紧固件的扭矩往往取决于操作人员根据工作经验来判断，存在超扭矩或超小的现象，不能准确满足紧固件紧固要求。因此，在机械行业，工作人员广泛使用扭矩扳手进行拧紧操作、控制或检测。
In addition, in the mechanical industry, the fastener's torque often depends on the operator's judgment based on work experience, there are super-torque or super-small phenomenon, can not accurately meet the fastener's fastening requirements. Therefore, in the machinery industry, staff widely use torque wrenches for tightening operation, control or detection.

扭矩扳手有很多种，根据动力来源可分为电动扭矩扳手、液压扭矩扳手和手动扭矩扳手;手动扭矩扳手可分为:信号型和直读型。在应用场景方面，信号扭矩扳手主要用于生产线扭矩控制，直读扭矩扳手主要用于扭矩质量检测。
There are many kinds of torque wrenches. According to the power source, they can be divided into electric torque wrench, hydraulic torque wrench and manual torque wrench. Manual torque wrench can be divided into signal type and direct reading type. In the application scenario, the signal torque wrench is mainly used for the production line torque control, and the direct reading torque wrench is mainly used for the torque quality detection.
在扳手头的选择上，棘轮式标准件是。扳手的头一般有棘轮、开口、梅花头和管钳。根据控制点的工作条件和安全因素，可以确定选用哪种头扭矩扳手。棘轮扳手是一种标准件，使用安全方便，成本低廉。
In the choice of wrench head, ratchet type standard parts are preferred. The head of wrench usually has ratchet wheel, opening, plum blossom head and pipe pliers. According to the working conditions and safety factors of the control point, it can be determined which kind of head torque wrench to choose. Ratchet wrench is a standard part, safe and convenient to use, low cost.
