電動扳手沒力原因可bai能是：1、電機損du壞；2：電池沒電。
The reason why the electric wrench has no force can be: 1. The motor is damaged; 2. The battery is dead.
電動扳手主要應用于鋼結(jié)zhi構(gòu)安裝dao行業(yè)，專門安裝鋼結(jié)構(gòu)高強螺栓，高強度螺栓是用來連接鋼結(jié)構(gòu)接點的，通常是用螺栓群的方式出現(xiàn)。高強螺栓可分為扭剪型和大六角型兩種，國標扭剪型高強螺栓為M16、M20、M22、M24四種，非國標的M27、M30兩種；國標大六角高強螺栓為M16、M20、M22、M24、M27、M30等幾種。一般的對于高強螺栓的緊固都要先初緊再終緊，而且每步都需要有嚴格的扭矩要求。大六角高強螺栓的初緊和終緊都必須使用定扭矩扳手.故各種電動扳手就是為各種緊固需要而來的。
Electric wrench is mainly used in steel structure installation Dao industry, which is used to install steel structure high strength bolts. High strength bolts are used to connect steel structure joints, usually in the form of bolt group. High strength bolts can be divided into two types: torsion shear type and large hexagon type. There are four kinds of national standard torsional shear high-strength bolts: M16, M20, M22 and M24, and non-national standard M27 and M30; 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 and then final tightening, and each step needs to have strict torque requirements. Constant torque wrench must be used in the initial and final tightening of large hexagon high strength bolts. Therefore, all kinds of electric spanners are for various tightening needs.

Application effect
沖擊電動扳手主要是初緊螺栓的，它的使用很簡單，就是對準螺栓扳動電源開關就行。電動扭剪扳手主要是終緊扭剪型高強螺栓的，它的使用就是對準螺栓扳動電源開關，直到把扭剪型高強螺栓的梅花頭打斷為止。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。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。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。
The impact electric wrench is mainly used to tighten the bolt, and its use is very simple, which is to align the bolt and pull the power switch. The main purpose of the electric wrench is to finally tighten the high-strength bolt. Its use is to align the bolt and pull the power switch until the plum head of the high-strength bolt is broken. The electric constant torque wrench can be used for initial tightening and final tightening. Its use is to adjust the torque first and then tighten the bolts. Electric angle wrench is also a kind of constant torque wrench. Its use is to adjust the rotation degree first, and then tighten the bolt. The electric angle wrench is a kind of electric wrench specially used to tighten the bolts at the angle of steel frame. Its use is the same as that of the electric twist shear wrench.

電動扭剪扳手顧名思義就是扭剪梅花頭螺栓擰緊作業(yè)的必備工具，幫助您裝、拆螺拴、螺母，同時能比較準確地控制擰緊扭矩。利用螺栓定扭矩，當扳手達到一定扭矩時即可剪斷螺栓的梅花頭部分，其扭矩精度和軸向拉力是靠螺栓的定扭矩V型切口來保證的。拆裝扭力矩大、比手工更保險可靠。方便、美觀、實用、便于隨車攜帶。廣泛用于鋼結(jié)構(gòu)橋梁、廠房、發(fā)電設備等設施的施工作業(yè)。
As the name suggests, it is necessary to tighten the nut and screw head with an electric wrench, which can help you to control the torque of the bolt. When the wrench reaches a certain torque, the plum head part of the bolt can be cut off by using the fixed torque of the bolt. The torque accuracy and axial tension are guaranteed by the V-shaped notch of the bolt with constant torque. Disassembly torque is large, more safe and reliable than manual. It is convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridge, workshop, power generation equipment and other facilities.
電動扳手的特點：（1）使用壽命長（2）手柄和機殼材料散熱性好（3）功率大（4）耐撞擊性強（5）手使用性價比
The characteristics of the electric wrench are: (1) long service life; (2) good heat dissipation of handle and casing; (3) high power; (4) strong impact resistance; (5) the best performance price ratio of hand use
電動扭剪扳手是一種終緊扭剪型高強度螺栓的工具，一般有電動扭剪扳手和手動扭剪扳手，其中電動扭剪扳手比較常見。
The electric twist shear wrench is a kind of tool for the final tightening of high-strength bolts. Generally, there are electric wrench and manual wrench, among which the electric wrench is more common.
扭剪扳手的應用： 扭剪型高強螺栓的初緊可使用沖擊電動扳手或定扭矩扳手,而終緊必須使用扭剪扳手，所以扭剪扳手是專門終緊扭剪型高強螺栓的。
Application of torsion shear wrench: the impact electric wrench or constant torque wrench can be used for the initial tightening of high-strength bolts, while the torsion shear wrench must be used for the final tightening. Therefore, the torsion shear wrench is specially used for the final tightening of the high-strength bolts.
扭剪扳手的使用： 扭剪扳手主要是終緊扭剪型高強螺栓的，它的目的就是把扭剪型高強螺栓的梅花頭打斷即可。工作時將扳手頭對準螺栓頭，扣動開關即可開始工作，幾秒后，螺栓梅花頭將被扭斷，然后抽出扳手扣動扳機將梅花頭彈出，即結(jié)束工作。
Use of twist shear wrench: the purpose of the wrench is to break the plum head of the high strength bolt. When working, the wrench head should be aligned with the bolt head, and the switch can be pulled to start the work. After a few seconds, the bolt plum head will be broken, and then pull out the wrench to pull the trigger to pop out the plum head, which is the end of the work.
扭剪扳手的特點： 操作方便、省時省力、方便。
The characteristics of twist shear wrench: easy to operate, time-saving and labor-saving, safe and convenient.
