電動(dòng)扳手有哪些類型，你知道嗎？
What types of electric wrenches do you know?
1、沖擊電動(dòng)扳手：主要用于初緊螺栓，操作簡單，只要對準(zhǔn)螺栓，按下電源開關(guān)就好了。
1. Impact electric wrench: it is mainly used for initial tightening of bolts. It is easy to operate. Just align the bolts and press the power switch.
2、電動(dòng)扭剪扳手：主要是終緊扭剪型高強(qiáng)螺栓的，使用方法是對準(zhǔn)螺栓按下電源開關(guān)，直到把扭剪型高強(qiáng)螺栓的梅花頭打斷為止。
2. Electric torsion shear wrench: it is mainly used to finally tighten the torsion shear high-strength bolt. The use method is to align the bolt and press the power switch until the plum blossom head of the torsion shear high-strength bolt is broken.
3、電動(dòng)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。
3. Electric constant torque wrench: it can be tightened initially and finally. Its use is to adjust the torque first and then tighten the bolts.
4、電動(dòng)轉(zhuǎn)角扳手：主要也屬于定扭矩扳手的一種，使用方法是先調(diào)節(jié)旋轉(zhuǎn)度數(shù)，再緊固螺栓。
4. Electric angle wrench: it mainly belongs to a kind of constant torque wrench. The use method is to adjust the rotation degree first, and then tighten the bolt.
5、電動(dòng)角向扳手：專門緊固鋼架夾角部位螺栓的電動(dòng)扳手，它的使用和電動(dòng)扭剪扳手原理是一樣的。
5. Electric angle wrench: it is an electric wrench specially used to fasten the bolts at the included angle of the steel frame. Its principle is the same as that of the electric torsion shear wrench.
選擇電動(dòng)扳手時(shí)候，我們需要考慮力量和速度。
When choosing an electric wrench, we need to consider strength and speed.
力量體現(xiàn)在扭力，大扭力的沖擊扳手可以扭動(dòng)更緊固的螺栓，進(jìn)行更多的作業(yè)。
The strength is reflected in the torque. The impact wrench with large torque can twist the tighter bolts and carry out more operations.
速度直接影響作業(yè)效率，扳手帶動(dòng)套筒高速旋轉(zhuǎn)，可以更快的裝卸螺栓。
The speed directly affects the operation efficiency. The wrench drives the sleeve to rotate at high speed, which can load and unload the bolts faster.
在我們?nèi)粘Ｉ钪校幸话讯喙δ艿臎_擊扳手，既實(shí)用又省力。
In our daily life, there is a multifunctional impact wrench, which is both practical and labor-saving.
這款鐵成911無刷鋰電定扭矩沖擊扳手，號稱是首臺定扭矩沖擊扳手，它有什么特點(diǎn)呢？
This Tiecheng 911 brushless lithium battery constant torque impact wrench is known as the first constant torque impact wrench. What are its characteristics?
什么叫定扭矩呢？定扭矩就是擰螺絲松緊，我們在操作的時(shí)候，可以設(shè)定某一個(gè)力矩（牛.米），機(jī)子就會(huì)自動(dòng)停止，這樣使用時(shí)，每一顆螺絲的松緊都是一致的（要一次擰到位才精準(zhǔn)），隔壁老的強(qiáng)迫癥都治好了。
What is constant torque? Constant torque is to tighten the screws. When we operate, we can set a certain torque (n · m) and the machine will stop automatically. In this way, the tightness of each screw is the same (it needs to be screwed in place at one time). Lao Wang's obsessive-compulsive disorder next door has been cured.
