电动扳手的优势

The advantages of electric wrenches

精准性高

High precision

工业电动扳手扭矩的调节是比较精准的，这样在进行实际操作的时候能够准确地拧紧扭矩，提高操作的效率。而质量比较差的电动扳手在操作的时候会出现距离上面的误差，影响正常使用。

The torque adjustment of industrial electric wrenches is relatively precise, so that the torque can be accurately tightened during actual operation, improving operational efficiency. However, electric wrenches with poor quality may experience distance errors during operation, which affects normal use.

使用寿命长

Long service life

电动扳手使用的寿命都比较长，功率也比较大，而且整体来说是比较省电的，早操作的时候也不会发出很大的噪声，因为在操作的时候难免会有发生撞击的情况，而好的电动扳手外部的材料比较坚固，所以比较耐撞击。

Electric wrenches have a relatively long lifespan, high power, and are generally more energy-efficient. They do not emit significant noise when operated early, as there may be collisions during operation. Good electric wrenches have sturdy external materials, making them more resistant to impacts.

散热性优良

Excellent heat dissipation

因为电动扳手在使用的过程中会产生多余的热量，所以好的电动扳手它的手柄和机壳材料的散热性一定要好。

Because electric wrenches generate excess heat during use, a good electric wrench must have good heat dissipation properties for its handle and casing material.

性价比更高

Higher cost-effectiveness

因为现在生产电动扳手的厂家有很多，市场竞争力强，合适的价位会提升产品的竞争力，所以工厂成本的管理和整体的定价是很重要的一个环节，口碑好的电动扳手性价比高。

Because there are many manufacturers producing electric wrenches now, with strong market competitiveness, a suitable price can enhance the competitiveness of the product. Therefore, cost management and overall pricing in the factory are important links. Electric wrenches with good reputation have high cost-effectiveness.

电动扳手的使用

The use of electric wrenches

选择正确的管状套筒

Choose the correct tubular sleeve

对于螺栓和螺母一定要使用大小合适的套筒。使用大小不合适的管状套筒将会导致固定扭矩的不精确和不协调或使螺栓螺母遭到损坏。

Be sure to use sleeves of appropriate size for bolts and nuts. The use of improperly sized tubular sleeves will result in inaccurate and inconsistent fixing torque or damage to bolts and nuts.

管状套筒的装配与拆卸

Assembly and disassembly of tubular sleeves

注意：在安装或拆卸管状套筒以前，一定要确保主机的电源开关出于断开状态，而且一定要拔下电源插销。

Attention: Before installing or removing the tubular sleeve, make sure that the power switch of the host is in the disconnected state, and be sure to unplug the power plug.

把O型圈移到套筒上的沟槽外面，并从套筒上拆下销子。把套筒安装在主机的钻头上，使钻头上的孔与套筒上的孔对准，将销子穿过套筒和钻头上的孔。把O型圈移回到套筒沟槽原来的位置上，以便使销子固定。拆卸套筒时可按安装时的相反顺序进行。

Move the O-ring outside the groove on the sleeve and remove the pin from the sleeve. Install the sleeve onto the drill bit of the host, aligning the holes on the drill bit with those on the sleeve, and thread the pin through the holes on the sleeve and drill bit. Move the O-ring back to its original position in the sleeve groove to secure the pin. When disassembling the sleeve, the reverse order of installation can be followed.
