顧名思義，電動扳手是擰緊螺絲的必備工具，它可以幫助你安裝和拆卸螺栓和螺母，準確控制擰緊力矩。在螺栓的固定力矩下，當扳手達到一定的力矩時，就可以切斷螺栓的桿頭部分。螺栓的固定力矩v形缺口保證了螺栓的扭矩精度和軸向拉力。拆卸扭矩大，比手動保險更可靠。方便、美觀、實用、便于攜帶。廣泛應用于鋼結構橋梁、廠房、發電設備等設施的施工。
As the name suggests, the electric wrench is a necessary tool for tightening screws. It can help you install and remove bolts and nuts, and accurately control the tightening torque. Under the fixed torque of the bolt, when the wrench reaches a certain torque, the rod head part of the bolt can be cut off. The fixed torque V-notch of the bolt ensures the torque accuracy and axial tension of the bolt. The disassembly torque is large, which is more reliable than manual safety. Convenient, beautiful, practical and portable. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.
電動扳手特點:(1)使用壽命長;(2)手柄、外殼材料散熱良好;(3)大功率;(4)抗沖擊性強;(5)手工使用的性價比
Electric wrench features: (1) long service life（ 2) Handle and shell materials have good heat dissipation（ 3) High power（ 4) Strong impact resistance（ 5) Cost performance of manual use
電動扳手是一種用于高強度螺栓端部緊固的工具，一般有電動扳手和手動扳手，其中電動扳手較為常見。
Electric wrench is a kind of tool used to fasten the end of high-strength bolt. There are generally electric wrench and manual wrench, among which electric wrench is more common.
扭力、剪力扳手的應用:扭力、剪力高強度螺栓的初始緊固可采用沖擊電動扳手或固定力矩扳手，扭力、剪力扳手的緊固必須采用扭力、剪力扳手。
Application of torque and shear wrench: impact electric wrench or fixed torque wrench can be used for the initial tightening of high strength bolts, and torque and shear wrench must be used for the tightening of torque and shear wrench.
扭剪扳手的使用:扭剪扳手主要是端部剪切的高強螺栓，其目的是剪切扭剪的高強螺栓可以斷裂。工作時，將扳手頭放在螺栓頭上，拉動開關開始工作，幾秒鐘后，螺栓頭將被扭緊，然后拔出扳手，扣動扳機，使棒子頭部彈出，即工作結束。
Use of torsional shear wrench: torsional shear wrench is mainly used for high-strength bolts sheared at the end. Its purpose is to shear the high-strength bolts sheared can be broken. When working, put the wrench head on the bolt head and pull the switch to start working. After a few seconds, the bolt head will be tightened. Then pull out the wrench and pull the trigger to make the rod head pop out, that is the end of the work.
特點:操作方便，省時省力，方便
Features: easy to operate, time-saving, safe and convenient
