Torsional shear wrench is mainly used to tighten torsional shear high-strength bolt. Its purpose is to break the quincunx head of torsional shear high-strength bolt. When working, align the wrench head with the bolt head, and pull the switch to start working. After a few seconds, the quincunx head of the bolt will be broken, and then pull out the wrench to pull the trigger to eject the quincunx head, which is the end of the work.

77779193永利首页网址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。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77779193永利首页网址就是为各种紧固需要而来的。使用效果冲击77779193永利首页网址主要是初紧螺栓的，它的使用很简单，就是对准螺栓扳动电源开关就行。

Electric wrench is mainly used in the steel structure installation industry, specially for the installation of steel structure high-strength bolts. High strength bolts are used to connect steel structure joints, usually in the form of bolt group. Constant torque wrench must be used for the initial tightening and final tightening of large hexagon high strength bolts. Therefore, all kinds of electric wrench are for all kinds of tightening needs. The use effect of the impact electric wrench is mainly the initial tightening of the bolt. Its use is very simple, that is, to align the bolt and pull the power switch.

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。

The electric wrench is mainly used to tighten the high-strength bolt. Its use is to align the bolt and pull the power switch until the quincunx head of the high-strength bolt is broken. The electric constant torque wrench can be used for both initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts.

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77779193永利首页网址，它的使用和电动扭剪扳手原理一样。性能

Electric angle wrench is also a kind of fixed torque wrench. Its use is to adjust the degree of rotation first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench which is specially used to fasten the bolts in the angle part of the steel frame. Its use principle is the same as that of the electric torsional shear wrench. performance

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.

As the name suggests, the electric wrench is a necessary tool for the tightening operation of the box head bolts. It can help you install and remove the bolts and nuts, and control the tightening torque more accurately. Use the bolt to fix the torque

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。

When the wrench reaches a certain torque, the box head part of the bolt can be cut, and its torque accuracy and axial tension are guaranteed by the V-shaped notch of the bolt. The torque of disassembly and assembly is large, which is more safe and reliable than manual operation. Convenient, beautiful, practical, easy to carry with the car. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.
