只有扭剪型电动扳手有内套筒。

Only torsion shear electric wrenches have inner sleeves.

冲击扳手适用于普通螺栓，定扭矩扳手适用于高强度螺栓(大陆角型)的初紧与终紧；扭剪扳手适用于高强度螺栓(梅花型)的终紧。

The impact wrench is suitable for ordinary bolts, and the constant torque wrench is suitable for the initial tightening and final tightening of high-strength bolts (Continental angle type); The torsion shear wrench is suitable for the final tightening of high-strength bolts (quincunx type).

注：冲击电动扳手的工作效率较高，一般每分钟冲击次数1000次以上。梅花型的高强螺栓的初紧可以用定扭矩电动扳手或冲击扳手，而一般来说大陆角型高强螺栓的施工工艺对初紧的扭矩精度要求较高，需要用相应扭矩的定扭矩扳手来施工。

Note: the working efficiency of impact electric wrench is high, generally more than 1000 times per minute. The fixed torque electric wrench or impact wrench can be used for the initial tightening of quincunx high-strength bolts. Generally speaking, the construction technology of continental angle high-strength bolts has high requirements for the torque accuracy of initial tightening, so the fixed torque wrench with corresponding torque is needed for construction.

不需要校验。

No verification is required.

不像定扭矩电动扳手，需要校验扭矩的精度，是否准确，扭剪型电动扳手只是将扭剪型高强螺栓的梅花头打断，既是完成了它的工作目的。

Unlike the fixed torque electric wrench, it is necessary to verify the accuracy of torque. The torsion shear electric wrench only breaks the plum blossom head of the torsion shear high-strength bolt, which is not only to complete its work purpose.

因为扭剪型电动扳手在使用时，将扭剪型电动扳手头对准扭剪型高强螺栓头，扣动开关即可开始工作，几秒后，螺栓梅花头将被扭断，抽出扳手扣动扳机将梅花头弹出，即结束工作。电动扳手主要应用于钢结构安装行业，专门安装钢结构高强螺栓，高强度螺栓是用来连接钢结构接点的，通常是用螺栓群的方式出现。高强螺栓可分为扭剪型和大六角型两种，国标扭剪型高强螺栓为M16、M20、M22、M24四种，现在也有非国标的M27、M30两种；国标大六角高强螺栓为M16、M20、M22、M24、M27、M30等几种。一般的对于高强螺栓的紧固都要先初紧再终紧，而且每步都需要有严格的扭矩要求。扭剪型高强螺栓的初紧可使用冲击电动扳手或定扭矩扳手,而终紧使用扭剪扳手;大六角高强螺栓的初紧和终紧都使用定扭矩扳手.故各种电动扳手就是为各种紧固需要而来的。

Because when the torsional shear electric wrench is in use, align the torsional shear electric wrench head with the torsional shear high-strength bolt head, pull the switch to start working. After a few seconds, the bolt plum blossom head will be broken. Pull out the wrench and pull the trigger to pop up the plum blossom head, that is, the work will be ended. 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. High strength bolts can be divided into torsion shear type and large hexagon type. There are four kinds of national standard torsion shear high strength bolts: M16, M20, M22 and M24, and now there are also two kinds of non-national standard M27 and M30; The national standard large hexagon high-strength bolts are M16, M20, M22, M24, M27, M30, etc. Generally, the tightening of high-strength bolts should be first tightened and then finally tightened, and strict torque requirements are required in each step. The impact electric wrench or fixed torque wrench can be used for the initial tightening of torsional shear high-strength bolts, while the torsional shear wrench is used for the final tightening; Constant torque wrenches are used for initial and final tightening of large hexagon high strength bolts Therefore, all kinds of electric wrenches are for various fastening needs.
