电动扭剪扳手具有自动控制扭矩的功能，是装配螺纹零件和螺栓的机械化施工工具，我厂电动扭剪扳手主机采用双绝缘单相串激电机和减速机构，结构新颖，体积小，重量轻，可靠，由于电动定扭矩扳手采用静扭矩结构，运行平稳，无振动、无冲击、无噪音，操作者不受反扭矩影响，劳动强度低，这种电动扭剪扳手广泛应用于大型机械、起重设备和车辆装配作业，以及对螺纹紧固件的扭矩和轴向拉力有严格要求的场合，那么如何拧紧电动扭剪扳手的螺栓要如何操作：
The electric torque wrench has the function of automatically controlling torque and is a mechanized construction tool for assembling threaded parts and bolts. Our factory's electric torque wrench host uses a double insulated single-phase series excitation motor and a reduction mechanism, with a novel structure, small size, light weight, and safety and reliability. Due to the static torque structure of the electric fixed torque wrench, it runs smoothly, without vibration, impact, or noise, and the operator is not affected by reverse torque, resulting in low labor intensity, This electric torque wrench is widely used in large-scale machinery, lifting equipment, and vehicle assembly operations, as well as in situations where there are strict requirements for the torque and axial tension of threaded fasteners. Therefore, how to tighten the bolts of the electric torque wrench and how to operate it:
1.安装反作用力支架并拧紧螺钉，启动主机，使方形销孔与反作用支架孔相对应，然后安装扳手套筒，插入销，用橡胶圈固定。
1. Install the reaction support bracket and tighten the screws, start the main engine so that the square pin hole corresponds to the reaction support bracket hole, then install the wrench socket, insert the pin, and fix it with a rubber ring.
2.将控制器的扭矩旋钮调节到所需的扭矩值，将主机的正反转开关设置到前进位置，将扳手套筒套在螺纹接头的六个面上。
2. Adjust the torque knob of the controller to the desired torque value, set the forward and reverse switches of the host to the forward position, and place the wrench socket on the six faces of the threaded joint.
3.按下电源开关启动扳手，当反力支架的力臂紧靠在支架上时(支点可以是相邻的螺栓或其他可以作为支点的位置)，螺栓开始拧紧，当螺栓的扭矩达到预定扭矩时，扳手会自动停止，完成紧固，松开电源开关，拧紧下一个螺栓。
3. Press the power switch to start the wrench. When the force arm of the reaction bracket is tightly against the bracket (the fulcrum can be an adjacent bolt or other position that can serve as a fulcrum), the bolt begins to tighten. When the bolt torque reaches the predetermined torque, the wrench will automatically stop and complete the tightening. Release the power switch and tighten the next bolt.
4.扳手自动停止后，通过反力支架的弹性变形力，支架的力臂自动脱离支点，扳手被取下，如果力臂脱离不了支点，可以拨动正反开关，然后点动电源开关扳手就可以拆下来。
4. After the wrench automatically stops, the force arm of the bracket automatically disengages from the fulcrum through the elastic deformation force of the counter force bracket, and the wrench is removed. If the force arm cannot detach from the fulcrum, the forward and backward switches can be toggled, and then the power switch wrench can be removed by clicking.
