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 wrenches are mainly used in the steel structure installation industry. They are specially used to install high-strength bolts of steel structure. High-strength bolts are used to connect steel structure joints, usually in the form of bolt groups.
高強螺栓按施工工藝分為扭剪型高強螺栓和大六角高強螺栓。其連接性能和本身的力學性能都是相同的，僅外形不同，都是以扭矩大小確定螺栓的軸向力大小。
According to the construction process, high-strength bolts are divided into torsional shear high-strength bolts and large hexagon high-strength bolts. Its connection performance and its own mechanical properties are the same, but the shape is different. The axial force of the bolt is determined by the torque.
緊固高強螺栓必須先初緊、后終緊，而初緊一般是緊固扭矩的一半，終緊就要緊固到扭矩值。大六角高強螺栓和普通螺絲外觀相似，初緊可以用沖擊扳手等，終緊必須用定扭矩電動扳手;而扭剪型高強螺栓前頭有一段梅花頭，初緊可以用沖擊扳手，終緊必須用扭剪型電動扳手，電動扭剪扳手可以比較準確地控制擰緊扭矩，利用螺栓定扭矩，當扳手達到一定扭矩時即可剪斷螺栓的梅花頭部分。其扭矩精度和軸向拉力是靠螺栓的定扭矩V型切口來保證的。
The high-strength bolts must be tightened first and then finally. The initial tightening is generally half of the maximum tightening torque, and the final tightening must be tightened to the maximum torque value. The appearance of large hexagon high-strength bolt is similar to that of ordinary screw. Impact wrench can be used for initial tightening, and constant torque electric wrench must be used for final tightening; There is a section of plum blossom head in front of the torsion shear high-strength bolt. The impact wrench can be used for initial tightening and the torsion shear electric wrench must be used for final tightening. The electric torsion shear wrench can accurately control the tightening torque and use the bolt to set the torque. When the wrench reaches a certain torque, the plum blossom head part of the bolt can be cut off. Its torque accuracy and axial tension are guaranteed by the constant torque V-notch of the bolt.
電動扭剪扭扳手配有內外兩個套管，外套筒扭螺母，對螺栓施加扭矩，內套筒方向扭梅花頭，兩個扭矩大小相等，方向相反，尾部梅花頭擰掉，讀出預拉力值。輕量型電動扭剪扳手：體積小、重量輕、距小適合狹窄空間操作。
The electric torsion shear wrench is equipped with two inner and outer sleeves, and the outer sleeve is used to twist the nut to apply torque to the bolt. The inner sleeve is used to twist the plum blossom head. The two torques are the same and the direction is opposite. Until the plum blossom head at the tail is screwed off, read out the pre tension value. Light weight electric torsion shear wrench: small volume, light weight and small center distance, suitable for operation in narrow space.
強力型電動扭剪扳手；速度快、扭矩大、剛性強，適合摩擦系數大和超高強螺栓的緊固。
Powerful electric torsion shear wrench; Fast speed, large torque and strong rigidity, suitable for fastening bolts with large friction coefficient and ultra-high strength.
轉向電動扭剪扳手：機械部分可0-360度旋轉，適合狹窄空間操作。
Steering electric torsion shear wrench: the mechanical part can rotate 0-360 degrees, which is suitable for operation in narrow space.
角向電動扭剪扳手：用于普通扳手無法達到的位置，如剛結構U型拐角、架構連接處以及一些狹窄部位的連接，體積小、重量輕。
Angle electric torsional shear wrench: it is used for positions that cannot be reached by ordinary wrenches, such as U-shaped corners of rigid structures, connections of structures and connections of some narrow parts. It has small volume and light weight.
