电动扭剪扳手是扭剪梅花头螺栓拧紧操作的必要工具，它可以帮助您安装和拆卸螺栓和螺母，同时可以准确控制拧紧力矩。使用螺栓的固定扭矩。当扳手达到一定扭矩时，螺栓的梅花头可以被切断。其扭矩精度和轴向张力由螺栓的固定扭矩V形切口保证。拆卸扭矩大，比手动可靠。方便、美观、实用、携带方便。广泛应用于钢结构桥梁、厂房、发电设备等设施的施工。
The electric torque wrench is a necessary tool for tightening the torx head bolt of the torque wrench. It can help you install and remove bolts and nuts, while accurately controlling the tightening torque. Use the fixing torque of the bolts. When the wrench reaches a certain torque, the ring head of the bolt can be cut off. The torque accuracy and axial tension are ensured by the V-shaped notch of the fixed torque of the bolt. High disassembly torque, safer and more reliable than manual operation. Convenient, beautiful, practical, and easy to carry. Widely used in the construction of steel structure bridges, factories, power generation equipment, and other facilities.
电动扭剪扳手的特点：（1）使用寿命长，（2）手柄和外壳材料散热性好，（3）功率高（4）抗冲击性强，（5）手用性价比很高。
The characteristics of electric torque wrench include: (1) long service life, (2) good heat dissipation of handle and shell materials, (3) high power, (4) strong impact resistance, and (5) high cost-effectiveness for manual use.
电动扭剪扳手是用于拧紧扭剪型高强度螺栓的工具。一般有电动扭剪扳手和手动扭剪扳手，其中电动扭剪扳手较为常见。
Electric torque wrench is a tool used to tighten high-strength bolts of torque type. There are generally electric shear wrenches and manual shear wrenches, among which electric shear wrenches are more common.
电动扭剪扳手的应用：扭剪高强度螺栓的初拧可以使用冲击电动扳手或恒扭矩扳手，而终拧须使用扭剪扳手，所以扭剪扳手是扭剪高强度螺栓终拧的专用扳手。
Application of electric torque wrench: Impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolts, while the final tightening requires the use of torque wrench. Therefore, torque wrench is a specialized wrench for the final tightening of high-strength bolts.
电动扭剪扳手的使用：扭剪扳手主要用于拧紧扭剪高强螺栓。其目的是折断扭剪高强度螺栓的梅花头。工作时，将扳手头与螺栓头对齐，拉动开关开始工作。几秒钟后，螺栓梅花头将被折断，然后拔出扳手并扳动扳机以弹出梅花头，这是工作的结束。
The use of electric torque wrench: The torque wrench is mainly used to tighten high-strength bolts with torque. Its purpose is to break the plum blossom head of high-strength bolts for torsional shear. When working, align the wrench head with the bolt head and pull the switch to start working. After a few seconds, the bolt head will be broken, and then the wrench will be pulled out and the trigger will be pulled to pop out the head, which is the end of the work.
电动扭剪扳手的维护：
Maintenance of electric torsion wrench:
1.做好定期保养：电液扳手长期使用后易磨损、生锈，尤其是棘轮、棘爪等部件磨损较大，应定期保养，更换损坏的部件，否则电液扳手将无法正常工作，直接影响工作过程；
1. Regular maintenance: Electric hydraulic wrenches are prone to wear and rust after long-term use, especially for parts such as ratchets and claws that are severely worn. Regular maintenance should be carried out and damaged parts replaced, otherwise the electric hydraulic wrench will not work properly and directly affect the working process;
2.掌握正确的操作方法：影响电液扳手使用寿命的因素之一是操作不合理。错误的操作方法不仅会导致设备无法正常工作，严重时还会造成设备损坏，因此要掌握正确的操作方法；
2. Master the correct operating method: One of the factors that affect the service life of the electric hydraulic wrench is improper operation. Incorrect operating methods not only prevent the equipment from working properly, but also cause equipment damage in severe cases. Therefore, it is necessary to master the correct operating methods;
3.如果电液扳手在使用中不能正常工作，应及时查找问题的根本原因，并及时修复。例如，如果设备漏油或压力不升高，则可能是由于连续工作导致设备高压漏油，或油缸密封圈损坏变形。注意不要使电动液压扳手过载。
3. If the electric hydraulic wrench cannot work properly during use, the root cause of the problem should be promptly identified and repaired. For example, if the equipment leaks oil or the pressure does not rise, it may be due to continuous operation causing high-pressure oil leakage or damage or deformation of the oil cylinder sealing ring. Be careful not to overload the electric hydraulic wrench.
除了定期维护电液扳手外，操作电液扳手时还应注意以下事项。电动液压扳手操作注意事项：
In addition to regular maintenance of the electric hydraulic wrench, the following precautions should also be taken when operating the electric hydraulic wrench. Precautions for operating electric hydraulic wrenches:
1.开机前须先确定开关状态，否则扳手会突然转动，容易造成意外伤害。连接漏电保护器，确保现场；
1. Before starting the machine, it is necessary to confirm the switch status first, otherwise the wrench will suddenly rotate and may cause accidental injury. Connect the leakage protector to ensure on-site safety;
2.如果电动液压扳手在使用中出现故障，应立即停机检查，排除故障后才能开始操作；
If there is a malfunction in the use of the electric hydraulic wrench, it should be stopped immediately for inspection, and the operation can only begin after the malfunction is eliminated;
3.电液扳手设备在使用过程中，如果现场条件恶劣且远离电源，应使用质量合格、容量足够的延长电缆。
3. During the use of the electro-hydraulic wrench equipment, if the on-site conditions are harsh and far from the power supply, qualified and sufficient capacity extension cables should be used.
