生活应用中扭力扳手的选择，在安装碳纤维零件和轻量化零件时，螺丝的紧固程度和均匀性尤为重要，而衡量这两项要素的指标则是安装时的扭矩。在正确的扭矩范围内，既能夹紧零件，又能防止滑牙或损坏。
For the selection of torque wrench in life application, when installing carbon fiber parts and lightweight parts, the tightening degree and uniformity of screws are particularly important, and the index to measure these two elements is the torque during installation. 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，紧固件的扭矩往往依靠操作工人凭工作经验判断，存在扭矩超大或超小的现象，不能精准达到紧固件的紧固要求。因此在机械行业中，工作人员广泛使用扭力扳手进行紧固操作、控制或检测。
In addition, in the machinery industry, the torque of fasteners often depends on the judgment of operators based on their work experience. There is a phenomenon that the torque is too large or too small, which can not accurately meet the fastening requirements of fasteners. Therefore, in the machinery industry, staff widely use torque wrench for fastening operation, control or detection.
扭力扳手种类繁多，按动力源可分为：电动扭力扳手、液压扭力扳手及手动扭力扳手；手动扭力扳手可分为：信号式和直读式。就应用场景而言，信号式扭力扳手主要用于生产流水线扭矩控制，直读式扭力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 terms of application scenarios, signal torque wrench is mainly used for torque control of production line, and direct reading torque wrench is mainly used for torque quality detection.
在扳手头部选择上，棘轮式标准件。扳手头部一般有棘轮、开口头、梅花头、管钳头等，根据使用控制点的工况、安全因素等来决定选用什么样头部的扭力扳手。棘轮式扳手，因其为标准件，安全方便，且成本较低。
In the selection of wrench head, ratchet type standard parts. The wrench head generally includes ratchet, opening, plum blossom head, pipe wrench head, etc. What kind of head torque wrench shall be selected according to the working conditions and safety factors of the control point. Ratchet wrench is a standard part, safe, convenient and low cost.
