電動扳手主要應用于鋼結構安裝行業(yè)，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(xiàn)。高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27
The electric wrench is mainly used in the steel structure installation industry to install steel structure high-strength bolts. 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: torsional shear type and large hexagon type. The national standard torsional shear type high strength bolts are M16, M20, M22 and M24, and the non national standard M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24 and M27
M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。大六角高強螺栓的初緊和終緊都使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
M30, etc. Generally, high-strength bolts shall be tightened first and then finally, and each step requires strict torque requirements. Fixed torque wrenches are used for the initial and final tightening of large hexagon high-strength bolts, so various electric wrenches are designed for various tightening needs.

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
The impact electric wrench is mainly used to tighten the bolts for the first time. It is very simple to use, that is, to align the bolts and pull the power switch. The electric shear wrench is mainly used to tighten the shear type high-strength bolt. It is used to pull the power switch against the bolt until the shear type
高強螺栓的梅花頭打斷為止。電動定扭矩扳手既可初緊又可終緊，它的使用是先調節(jié)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(jié)旋轉度數(shù)，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 quincunx head of high-strength bolt is broken. The electric constant torque wrench can be used for initial tightening and final tightening. It is used to adjust the torque before tightening the bolts. The electric angle wrench is also a kind of constant torque wrench. It is used to adjust the rotation degree before tightening the bolts. The electric angle wrench is an electric wrench specially used to fasten the bolts at the angle of the steel frame, and its use is the same as the principle of the electric torque shear wrench.

電動扭剪扳手顧名思義就是扭剪梅花頭螺栓擰緊作業(yè)的工具，幫助您裝、拆螺拴、螺母，同時能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
As the name implies, the electric torque wrench is a tool for torshear torx head bolt tightening operation, which can help you install and remove bolts and nuts, and control the tightening torque more accurately. The fixed torque of the bolt is used. When the wrench reaches a certain torque, the box head of the bolt can be cut off. The torque accuracy and axial tension depend on the fixed torque V of the bolt
型切口來保證的。拆裝扭力矩大、比手工更保險可靠。方便、美觀、實用、便于隨車攜帶。廣泛用于鋼結構橋梁、廠房、發(fā)電設備等設施的施工作業(yè)。
Type notch. The disassembly torque is large, more reliable than manual. Convenient, beautiful, practical and easy to carry with the vehicle. It is widely used in the construction of steel structure bridges, plants, power generation equipment and other facilities.
