　　电动扳手是电源或蓄电池供电的扳手，是拧紧螺栓的工具。它主要用于钢结构安装行业，特别是用于钢结构高强螺栓的安装，高强螺栓用于连接钢结构的触点，通常采用螺栓组的形式。

　　Electric wrench is a wrench powered by power or battery and a tool for tightening bolts. It is mainly used in the steel structure installation industry, especially for the installation of high-strength bolts in steel structures. High-strength bolts are used to connect the contacts of steel structures, usually in the form of bolt groups.

　　气动扳手又称棘轮扳手和电动工具总成，主要是一种以比较小的消耗提供高扭矩输出的工具。它利用连续的动力源来加速具有一定质量的物体的旋转，然后瞬间击中输出轴，从而获得较大的扭矩输出。压缩空气是比较常见的动力来源，尽管有些使用电动或液压。

　　Pneumatic wrench, also known as ratchet wrench and electric tool assembly, is mainly a tool to provide high torque output with minimum consumption. It uses a continuous power source to accelerate the rotation of a body with a certain mass, and then instantaneously hits the output axis to obtain a larger output of torque. Compressed air is the most common source of power, although some use electric or hydraulic power.

　　此外，气动扳手可在每一个标准棘轮套筒驱动器大小，从一个小的1/4 ""驱动套件套件安装和拆卸到3.5" "。气动扳手一般不适用于陶瓷和塑料安装件的紧固。

　　In addition, the pneumatic wrench can be installed and disassembled from a small 1/4"drive kit to 3.5" for each standard ratchet sleeve drive size. Pneumatic wrenches are generally not suitable for the fastening of ceramic and plastic fittings.

　　出故障了

　　It's out of order.

　　确认现场连接的电源是否与电动扳手铭牌一致。是否有漏电保护器连接?如无异常或不使用，应送维修店检查。

　　Verify that the power supply connected on site is consistent with the nameplate of the electric wrench. Are there leakage protector connections? If there is no abnormality or no use, it should be sent to the brand repair shop for inspection.
