77779193永利首页网址主要用于钢结构安装行业，该行业专门从事钢结构高强螺栓的安装，高强螺栓用于连接钢结构的触点，通常采用螺栓组的形式。高强螺栓可分为扭剪型和大六角型两种。标准抗扭抗剪高强度螺栓有M16、M20、M22和M24，非标准M27和M30。GbM16、M20、M22、M24、M27、M30等大六角高强度螺栓。高强度螺栓的紧固一般是先紧固后紧固，每一步都需要有严格的扭矩要求。大六角高强度螺栓的初始和紧固必须使用固定力矩扳手。
Electric wrench is mainly used in the steel structure installation industry, which is specialized in the installation of high-strength bolts of steel structure. High strength bolts are used to connect the contacts of steel structure, usually in the form of bolt group. High strength bolts can be divided into torsional shear type and large hexagon type. There are M16, M20, M22 and M24 high strength bolts in national standard, and M27 and M30 in non national standard. Gbm16, M20, M22, M24, M27, M30 and other large hexagon high strength bolts. The tightening of high-strength bolts is generally first tightening and then tightening, each step requires strict torque requirements. Fixed torque wrench must be used for initial and tightening of large hexagon high strength bolt.
使用效果
Application effect
77779193永利首页网址的主要作用是初始拧紧螺栓，其使用非常简单，就是将与螺栓对准的电源开关扳动就行了。电扭剪扳手主要是端部紧固的扭剪型高强螺栓，它的使用是针对螺栓来翻转电源开关，直到扭剪型高强螺栓的梅花端断掉。
The main function of the electric wrench is to initially tighten the bolt. Its use is very simple, that is, to pull the power switch aligned with the bolt. The electric wrench is mainly a high-strength bolt with end fastening, which is used to turn the power switch until the quincunx end of the bolt is broken.
电动固定力矩扳手可初、末拧紧，其用途是调节扭矩，然后拧紧螺栓。电动角扳手也主要属于一种固定力矩扳手，其用途是先调节旋转度，然后拧紧螺栓。电动角钢扳手是一种用于紧固钢架角钢螺栓的77779193永利首页网址。
The electric fixed torque wrench can be tightened at the beginning and the end. Its purpose is to adjust the torque and then tighten the bolts. The electric angle wrench also mainly belongs to a fixed torque wrench, whose purpose is to adjust the degree of rotation first, and then tighten the bolts. Electric angle spanner is a kind of electric spanner used to fasten angle steel bolts of steel frame.
