The electric wrench is mainly used in the steel structure installation industry to install steel structure high-strength bolts. High strength bolts are used to connect steel structure joints, usually in the form of bolt groups. High strength bolts can be divided into two types: torsional shear type and large hexagon type. The national standard torsional shear type high strength bolts are M16, M20, M22 and M24, and the non national standard M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24 and 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。大六角高强螺栓的初紧和终紧都使用定扭矩扳手.故各种必威西汉姆联官网g1线路就是为各种紧固需要而来的。

M30, etc. Generally, high-strength bolts shall be tightened first and then finally, and each step requires strict torque requirements. Fixed torque wrenches are used for the initial and final tightening of large hexagon high-strength bolts, so various electric wrenches are designed for various tightening needs.

冲击必威西汉姆联官网g1线路主要是初紧螺栓的，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

The impact electric wrench is mainly used to tighten the bolts for the first time. It is very simple to use, that is, to align the bolts and pull the power switch. The electric shear wrench is mainly used to tighten the shear type high-strength bolt. It is used to pull the power switch against the bolt until the shear type

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必威西汉姆联官网g1线路，它的使用和电动扭剪扳手原理一样。

The quincunx head of high-strength bolt is broken. The electric constant torque wrench can be used for initial tightening and final tightening. It is used to adjust the torque before tightening the bolts. The electric angle wrench is also a kind of constant torque wrench. It is used to adjust the rotation degree before tightening the bolts. The electric angle wrench is an electric wrench specially used to fasten the bolts at the angle of the steel frame, and its use is the same as the principle of the electric torque 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

As the name implies, the electric torque wrench is a tool for torshear torx head bolt tightening operation, which can help you install and remove bolts and nuts, and control the tightening torque more accurately. The fixed torque of the bolt is used. When the wrench reaches a certain torque, the box head of the bolt can be cut off. The torque accuracy and axial tension depend on the fixed torque V of the bolt

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。

Type notch. The disassembly torque is large, more reliable than manual. Convenient, beautiful, practical and easy to carry with the vehicle. It is widely used in the construction of steel structure bridges, plants, power generation equipment and other facilities.
