In our daily life, we often encounter the time of disassembling tools and repairing screws. At this time, the electric wrench will be a good choice. Electric wrench is also known as electric torsion wrench. Generally, the torque is determined by bolts. When the distance reaches a certain degree, we can cut the part of the box head. What are the advantages of electric wrench?

1、精准性高

1. High accuracy

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回出现距离上面的误差，影响正常使用。

Industrial electric wrench torque adjustment is more accurate, so in the actual operation can accurately tighten the torque, improve the efficiency of operation. The quality of the electric wrench is relatively poor in the operation of the distance error, affect the normal use.

2、使用寿命长

2. 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。

The service life of the electric wrench is relatively long, the power is relatively large, and on the whole, it is relatively energy-saving, and it will not make a lot of noise when operating early, because it is inevitable that there will be impact when operating, and the external material of a good electric wrench is relatively strong, so it is more impact resistant.

3、散热性优良

3. 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 the electric wrench in the process of use will produce excess heat, so a good electric wrench its handle and shell material heat dissipation must be better.

4、性价比更高

4. More cost-effective

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 spanners, and the market competitiveness is strong. The appropriate price will enhance the competitiveness of the products, so the cost management and overall pricing of the factory are very important. The electric spanners with good reputation have high cost performance.

综上所述，品质好的电动扳手不仅做功优良、使用寿命长、散热性、在价位上也具有很大优势，性价比高。由于一般在工厂机械设备的检修中电动扳手使用的频率比较高，因此在选择电动扳手的时候品质好的电动扳手更具有优势。此外的电动扳手它的售后服务也比较好，值得信赖。

To sum up, good quality electric wrench not only has excellent work, long service life, heat dissipation, but also has great advantages in price and high cost performance. Due to the high frequency of using electric wrench in the maintenance of mechanical equipment in the factory, when choosing electric wrench, the electric wrench with good quality has more advantages. In addition, the electric wrench, its after-sales service is also relatively good, trustworthy.
