在開始更換操作之前，檢查彈射桿是否伸入內套筒。如果沒有，操作頂出銷伸出，然后更換。
Before starting the replacement operation, check whether the ejection rod extends into the inner sleeve. If not, extend the ejector pin and replace it.
拆卸套筒時，拉動頂桿。當意外觸碰彈射扳機時，它可能會突然彈出。
Pull the ejector rod when removing the sleeve. When accidentally touching the ejection trigger, it may pop up suddenly.
1.每個套筒分為內部和外部零件，拆卸時，先取出外套筒，然后取出內套筒。
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.準備并擰緊適合螺栓類型的內外套筒。
2. Prepare and tighten the inner and outer sleeves suitable for the bolt type.
3.套筒的拆卸：用力按壓外套管，用六角螺絲刀拆下主體和外套管之間的連接，然后按壓彈射桿，以防彈射造成傷害。
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.
電動扭剪扳手的應用：產品可用于剪切型高強度螺栓的初始擰緊，擰緊需要使用剪切扳手，因此剪切扳手專門用于剪切型高強螺栓的擰緊。
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．電動扭剪扳手的工作原理：電動扭力剪扳手有內外兩個套筒。外套管扭轉螺母，向螺栓施加扭矩。內套筒扭轉盒頭。兩個扭矩大小相等，方向相反，直到擰下末端的箱頭。然后拔出扳手并扳動扳機，彈出盒頭，這就結束了工作。
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.
電動扭剪扳手的優點
Advantages of electric torque wrench
1.體積小、重量輕、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.產品電機采用德國原裝進口，比國產電機體積小、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.整機人性化設計，手柄采用人體工程力學原理，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.電源線是一種由TPU材料制成的特殊電纜，通常用于惡劣的工作條件。它具有優異的耐磨性、抗彎性和抗滾動性。它的是同規格電纜的3倍多，但可以完全防止電纜斷裂的問題
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.這個機器齒輪由超高強度鋼制成，強度是普通鋼的兩倍
5. This machine gear is made of ultra-high strength steel, which is twice as strong as ordinary steel
6.電動扭剪扳手相對容易操作，降低了工人的勞動強度，提高了工作效率。現在市場上有很多電動扳手的制造商，所以選擇一個好的產品制造商很重要。
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.
