Electric wrench is a power supply or battery powered wrench, is a tool to tighten high strength bolts, also known as high strength bolt gun. It is mainly divided into impact wrench, torsion wrench, constant torque wrench, angle wrench and angle wrench.

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。

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.

特点是机身轻巧， 噪音少，使用寿命长，装配螺纹零件速度比一般手工按装提高十，品质 已经达到倍世界进水平，价 格是欧美、日本生产的电动扳手的十分之一， 结构上比过去生产的笨重电板手手轻得多，用户情有独钟。

It is characterized by light body, low noise and long service life. The assembly speed of threaded parts is ten times faster than that of ordinary manual assembly. The quality has reached the world advanced level. The price is one tenth of that of electric wrench produced in Europe, America and Japan. The structure is much lighter than that of heavy electric wrench produced in the past. Users have a special preference for it.

使用效果

Application effect

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。

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 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.

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 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. 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.
