在开始更换操作之前，检查弹射杆是否伸入内套筒。如果没有，操作顶出销伸出，然后更换。
Before starting the replacement operation, check whether the ejection rod extends into the inner sleeve. If not, extend the ejector pin and replace it.
拆卸套筒时，拉动顶杆。当意外触碰弹射扳机时，它可能会突然弹出。
Pull the ejector rod when removing the sleeve. When accidentally touching the ejection trigger, it may pop up suddenly.
1.每个套筒分为内部和外部零件，拆卸时，先取出外套筒，然后取出内套筒。
1. Each sleeve is divided into internal and external parts. When disassembling, take out the outer sleeve first, and then take out the inner sleeve.
2.准备并拧紧适合螺栓类型的内外套筒。
2. Prepare and tighten the inner and outer sleeves suitable for the bolt type.
3.套筒的拆卸：用力按压外套管，用六角螺丝刀拆下主体和外套管之间的连接，然后按压弹射杆，以防弹射造成伤害。
3. Disassembly of sleeve: press the outer sleeve firmly, remove the connection between the main body and the outer sleeve with a hexagon screwdriver, and then press the ejection rod to prevent injury caused by ejection.
电动扭剪扳手的应用：产品可用于剪切型高强度螺栓的初始拧紧，拧紧需要使用剪切扳手，因此剪切扳手专门用于剪切型高强螺栓的拧紧。
Application of electric torque wrench: the product can be used for the initial tightening of shear-type high-strength bolts. The tightening requires the use of a shear wrench, so the shear wrench is specially used for the tightening of shear-type high-strength bolts.
四．电动扭剪扳手的工作原理：电动扭力剪扳手有内外两个套筒。外套管扭转螺母，向螺栓施加扭矩。内套筒扭转盒头。两个扭矩大小相等，方向相反，直到拧下末端的箱头。然后拔出扳手并扳动扳机，弹出盒头，这就结束了工作。
4、 Working principle of electric torque shear wrench: electric torque shear wrench has two sockets inside and outside. Torque the nut on the outer sleeve to apply torque to the bolt. The inner sleeve twists the box head. The two torques are equal in size and opposite in direction, until the box head at the end is unscrewed. Then pull out the wrench and pull the trigger to pop out the box head, which ends the work.
电动扭剪扳手的优点
Advantages of electric torque wrench
1.体积小、重量轻、扭剪速度快，可提高施工效率。
1. Small volume, light weight and fast shear speed can improve construction efficiency.
2.产品电机采用德国原装进口，比国产电机体积小、功率大。
2. The motor of the product is imported with original packaging from Germany, which is smaller and larger than the domestic motor.
3.整机人性化设计，手柄采用人体工程力学原理，握持更舒服。
3. The whole machine is humanized, and the handle adopts the principle of human engineering mechanics, which makes it more comfortable to hold.
4.电源线是一种由TPU材料制成的特殊电缆，通常用于恶劣的工作条件。它具有优异的耐磨性、抗弯性和抗滚动性。它的是同规格电缆的3倍多，但可以完全防止电缆断裂的问题
4. The power cord is a special cable made of TPU material, which is usually used in harsh working conditions. It has excellent wear resistance, bending resistance and rolling resistance. Its price is more than three times that of cables of the same specification, but it can completely prevent cable breakage
5.这个机器齿轮由超高强度钢制成，强度是普通钢的两倍
5. This machine gear is made of ultra-high strength steel, which is twice as strong as ordinary steel
6.电动扭剪扳手相对容易操作，降低了工人的劳动强度，提高了工作效率。现在市场上有很多电动扳手的制造商，所以选择一个好的产品制造商很重要。
6. The electric torsion wrench is relatively easy to operate, which reduces the labor intensity of workers and improves work efficiency. There are many manufacturers of electric wrenches on the market, so it is important to choose a good product manufacturer.
