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(duì)于高強(qiáng)螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴(yán)格的扭矩要求。大六角高強(qiáng)螺栓的初緊和終緊都使用定扭矩扳手.故各種電動(dòng)扳手就是為各種緊固需要而來(lái)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(dòng)扳手主要是初緊螺栓的，它的使用很簡(jiǎn)單，就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)就行。電動(dòng)扭剪扳手主要是終緊扭剪型高強(qiáng)螺栓的，它的使用就是對(duì)準(zhǔn)螺栓扳動(dòng)電源開關(guān)，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(qiáng)螺栓的梅花頭打斷為止。電動(dòng)定扭矩扳手既可初緊又可終緊，它的使用是先調(diào)節(jié)扭矩，再緊固螺栓。電動(dòng)轉(zhuǎn)角扳手主要也屬于定扭矩扳手的一種，它的使用是先調(diào)節(jié)旋轉(zhuǎn)度數(shù)，再緊固螺栓。電動(dòng)角向扳手是一種專門緊固鋼架夾角部位螺栓的電動(dòng)扳手，它的使用和電動(dòng)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(dòng)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(shí)能比較準(zhǔn)確地控制擰緊扭矩。利用螺栓定扭矩，當(dāng)扳手達(dá)到一定扭矩時(shí)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(lái)保證的。拆裝扭力矩大、比手工更保險(xiǎn)可靠。方便、美觀、實(shí)用、便于隨車攜帶。廣泛用于鋼結(jié)構(gòu)橋梁、廠房、發(fā)電設(shè)備等設(shè)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.
