Unlike the fixed torque electric wrench, it needs to check the accuracy and accuracy of the torque. The torque electric wrench only breaks the ring head of the high-strength bolt, which is the purpose of its work.

因为扭剪型电动扳手在使用时，将扭剪型电动扳手头对准扭剪型高强螺栓头，扣动开关即可开始工作，几秒后，螺栓梅花头将被扭断，抽出扳手扣动扳机将梅花头弹出，即结束工作。电动扳手主要应用于钢结构安装行业，专门安装钢结构高强螺栓，高强度螺栓是用来连接钢结构接点的，通常是用螺栓群的方式出现。高强螺栓可分为扭剪型和大六角型两种，国标扭剪型高强螺栓为M16、M20、M22、M24四种，现在也有非国标的M27、M30两种；国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧，而且每步都需要有严格的扭矩要求。扭剪型高强螺栓的初紧可使用冲击电动扳手或定扭矩扳手,而终紧必须使用扭剪扳手;大六角高强螺栓的初紧和终紧都必须使用定扭矩扳手.故各种电动扳手就是为各种紧固需要而来的。

Because when the electric wrench is used, align the head of the electric wrench with the head of the high-strength bolt, and then turn the switch to start working. After a few seconds, the bolt ring head will be broken. Pull out the wrench and pull the trigger to pop out the ring head, and then the work will be finished. Electric spanner is mainly used in steel structure installation industry. It is specially used to install high-strength bolts of steel structure. High strength bolts are used to connect steel structure joints, usually in the way of bolt group. High strength bolts can be divided into two types: torsional shear type and large hexagon type. There are four kinds of national standards: M16, M20, M22 and M24. Now there are two kinds of non-national standards: M27 and M30. The national standards are M16, M20, M22, M24, M27 and M30. Generally, for the fastening of high-strength bolts, the initial tightening and then the final tightening are required, and strict torque requirements are required for each step. The impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolt of torsional shear type, while the torsional shear wrench must be used for the final tightening; the constant torque wrench must be used for the initial tightening and final tightening of large hexagon high-strength bolt, so all kinds of electric wrenches are for various tightening needs.

冲击电动扳手主要是初紧螺栓的，它的使用很简单，就是对准螺栓扳动电源开关就行。电动扭剪扳手主要是终紧扭剪型高强螺栓的，它的使用就是对准螺栓扳动电源开关，直到把扭剪型高强螺栓的梅花头打断为止。电动定扭矩扳手既可初紧又可终紧，它的使用是先调节扭矩，再紧固螺栓。电动转角扳手主要也属于定扭矩扳手的一种，它的使用是先调节旋转度数，再紧固螺栓。电动角向扳手是一种专门紧固钢架夹角部位螺栓的电动扳手，它的使用和电动扭剪扳手原理一样。

The impact electric wrench is mainly used to tighten the bolt initially. Its use is very simple, that is to align the bolt and pull the power switch. The electric torque wrench is mainly used to tighten the torque shear type high-strength bolt. Its use is to align the bolt and pull the power switch until the plum head of the torque shear type high-strength bolt is interrupted. The electric constant torque wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. The electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the rotation degree first and then fasten the bolts. The electric angle wrench is a kind of electric wrench specially used to fasten the bolts in the angle part of the steel frame. Its use is the same as the principle of the electric torsional shear wrench.

电动扭剪扳手顾名思义就是扭剪梅花头螺栓拧紧作业的必备工具，帮助您装、拆螺拴、螺母，同时能比较准确地控制拧紧扭矩。利用螺栓定扭矩，当扳手达到一定扭矩时即可剪断螺栓的梅花头部分，其扭矩精度和轴向拉力是靠螺栓的定扭矩V型切口来保证的。拆装扭力矩大、比手工更保险可靠。方便、美观、实用、便于随车携带。广泛用于钢结构桥梁、厂房、发电设备等设施的施工作业。

As the name implies, the electric wrench is a necessary tool for the tightening operation of the box head bolt of the torsional shear. It helps you to install and remove the bolt and nut, and at the same time, it can control the tightening torque more accurately. When the spanner reaches a certain torque, the ring head of the bolt can be cut off. The torque accuracy and axial tension are guaranteed by the V-notch of the bolt. The assembly and disassembly torque is large, more safe and reliable than manual operation. Convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.

Features of electric wrench: (1) long service life (2) good heat dissipation of handle and shell material (3) high power (4) strong impact resistance (5) cost performance of hand use

电动扭剪扳手是一种终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，其中电动扭剪扳手比较常见。

Electric wrench is a kind of tool for final tightening of high-strength bolts. Generally, there are electric wrench and manual wrench, among which electric wrench is common.

扭剪扳手的应用：  扭剪型高强螺栓的初紧可使用冲击电动扳手或定扭矩扳手,而终紧必须使用扭剪扳手，所以扭剪扳手是专门终紧扭剪型高强螺栓的。

Application of torque wrench: impact electric wrench or constant torque wrench can be used for the initial tightening of torque shear type high-strength bolt, while torque wrench must be used for final tightening, so torque wrench is specially used for final tightening of torque shear type high-strength bolt.

扭剪扳手的使用：  扭剪扳手主要是终紧扭剪型高强螺栓的，它的目的就是把扭剪型高强螺栓的梅花头打断即可。工作时将扳手头对准螺栓头，扣动开关即可开始工作，几秒后，螺栓梅花头将被扭断，然后抽出扳手扣动扳机将梅花头弹出，即结束工作。

Use of the wrench: the wrench is mainly used to tighten the high-strength bolt. Its purpose is to break the ring head of the bolt. When working, align the spanner head with the bolt head, and turn the switch to start working. After a few seconds, the bolt ring head will be broken, and then pull out the spanner to turn the trigger to pop out the ring head, which is the end of the work.
