77779193永利首页网址主要应用领域：

The main application areas of electric wrenches are:

　　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。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。

Electric wrenches are mainly used in the steel structure installation industry, specifically for installing high-strength bolts for steel structures. 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: torsion shear type and large hexagonal type. The national standard torsion shear type high strength bolts are M16, M20, M22, and M24, and now there are also non national standard M27 and M30 types; The national standard large hexagonal high-strength bolts include several types such as M16, M20, M22, M24, M27, M30, etc.

　　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77779193永利首页网址或定扭矩扳手,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77779193永利首页网址就是为各种紧固需要而来的。

Generally, the tightening of high-strength bolts requires initial tightening before final tightening, and each step requires strict torque requirements. The initial tightening of torsion shear high-strength bolts can be achieved using an impact electric wrench or a fixed torque wrench, while the final tightening must be achieved using a torsion shear wrench; The initial and final tightening of large hexagonal high-strength bolts must use a fixed torque wrench. Therefore, various electric wrenches are designed for various tightening needs.

　　77779193永利首页网址的使用方法:

Instructions for using an electric wrench:

　　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。

The impact electric wrench is mainly used for initial tightening of bolts, and its use is very simple, just 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。

The electric torque wrench is mainly used for final tightening torque shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torque shear high-strength bolt is broken.

　　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。数显电动扭矩扳手液晶屏直接显示扭矩值，操作比较直观方便。

The electric fixed torque wrench can be used for both initial and final tightening. Its use involves adjusting the torque first and then tightening the bolts. The digital electric torque wrench directly displays the torque value on the LCD screen, making the operation more intuitive and convenient.

　　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。

Electric corner wrenches mainly belong to a type of fixed torque wrench, which is used to adjust the degree of rotation first and then tighten the bolts.

　　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。

Electric angle wrench is a type of electric wrench specifically designed to tighten bolts at the angle of a steel frame, and its use is similar to the principle of an electric torsion wrench.
