冲击扳手适用于普通螺栓,固定力矩扳手适用于高强度螺栓(大陆角)初、终紧固;该扳手适用于高强度螺栓(李子)的紧固。

The impact wrench is suitable for ordinary bolts, and the fixed torque wrench is suitable for the initial and final fastening of high strength bolts (Continental angle); The wrench is suitable for fastening high strength bolts (plums).
注:电动冲击电动扳手工作效率高,一般每分钟冲击1000次以上。梅花型高强螺栓的初紧固可采用固定力矩电动扳手或冲击扳手进行。大陆角高强螺栓的施工工艺一般对初紧力矩精度要求较高。
Note: the working efficiency of electric impact wrench is high, generally more than 1000 times per minute. Fixed torque electric wrench or impact wrench can be used for initial tightening of high strength box bolts. The construction technology of high-strength bolts with Continental angle generally requires high accuracy of initial tightening torque.
不需要检查扭矩-剪切电动扳手。
There is no need to check the torque shear electric wrench.
与固定扭矩电动扳手不同,扭剪电动扳手需要验证扭矩的准确性以及是否准确。
Different from the fixed torque electric wrench, the electric wrench of torsion shear needs to verify the accuracy and accuracy of torque.
