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(zhǔn)螺栓扳動電源開關(guān)就行。
The impact electric wrench is mainly used for initial tightening of bolts, and its use is very simple, which is to align the bolt and pull the power switch.
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(zhǔn)螺栓扳動電源開關(guān)，直到把扭剪型高強螺栓的梅花頭打斷為止。
The electric torque wrench is mainly used for final tightening of torque shear high-strength bolts. Its use is to align the bolt and pull the power switch until the plum blossom head of the torque shear high-strength bolt is broken.
電動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。
The electric fixed torque wrench can be used for both initial and final tightening. Its use involves adjusting the torque first and then tightening the bolts.
電動轉(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。
Electric angle wrenches mainly belong to a type of fixed torque wrench, which is used to adjust the rotation degree first and then tighten the bolts.
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。
Electric angle wrench is a type of electric wrench specifically designed to tighten bolts at the angle of a steel frame, and its use is the same as that of an electric torsion wrench.
氣動沖擊扳手
air impact wrench
用于金屬模具修理的夾具
Fixture for metal mold repair
氣動沖擊扳手，沖擊錘是與氣動馬達(dá)直接連接的。電動沖擊扳手不能用于高熱量的環(huán)境 沖擊扳手用于在金屬模具上擰緊/拆卸夾具。
Pneumatic impact wrench, the impact hammer is directly connected to the pneumatic motor. Electric impact wrenches cannot be used in high heat environments. Impact wrenches are used to tighten/disassemble fixtures on metal molds.
原理
principle
通過高壓氣體（一般為6.2Kgf）驅(qū)動氣動馬達(dá)機構(gòu)旋轉(zhuǎn)，再通過轉(zhuǎn)子輸出至打擊機構(gòu)，打擊機構(gòu)帶動打擊軸形成循環(huán)往復(fù)的前后及旋轉(zhuǎn)運動。
The pneumatic motor mechanism is driven to rotate by high-pressure gas (usually 6.2Kgf), and then output to the striking mechanism through the rotor. The striking mechanism drives the striking shaft to form a cyclic forward backward and rotational motion.
