電動扳手就是以電源或電池為動力的扳手，是一種擰緊高 強度螺栓的工具，又叫高 強螺栓槍。主要分為沖擊扳手、扭剪扳手、定扭矩扳手、轉角扳手、角向扳手。
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.
電動扳手主要應用于鋼結構安裝行業，專門安裝鋼結構高 強螺栓，高 強度螺栓是用來連接鋼結構接點的，通常是用螺栓群的方式出現。
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.
特點是機身輕巧，噪音少，使用壽命長，裝配螺紋零件速度比一般手工按裝提高十，品質已經達到倍世界進水平，價 格是歐美、日本生產的電動扳手的十分之一，結構上比過去生產的笨重電板手手輕得多，用戶情有獨鐘。
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
沖擊電動扳手主要是初緊螺栓的，它的使用很簡單，就是對準螺栓扳動電源開關就行。電動扭剪扳手主要是終緊扭剪型高 強螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高 強螺栓的梅花頭打斷為止。
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.
電動定扭矩扳手既可初緊又可終緊，它的使用是先調節扭矩，再緊固螺栓。電動轉角扳手主要也屬于定扭矩扳手的一種，它的使用是先調節旋轉度數，再緊固螺栓。電動角向扳手是一種專門緊固鋼架夾角部位螺栓的電動扳手，它的使用和電動扭剪扳手原理一樣。
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.
