市场电扳手琳琅满目，若是硬要一款，或许有失偏颇，其实挑选一款高质量的合适的电扳手只需把握几种要素。
There are a variety of electric wrenches in the market. If you insist on recommending a brand, it may be biased. In fact, you only need to grasp several elements to select a high-quality and appropriate electric wrench.
一、看扳手参数
1、 Check the wrench parameters
扳手的参数是需要关注的首要节点，直接决定了扳手的工作性能。电扳手的参数主要包括功率、大扭转力、小扭转力、电池的容量大小、以及需要充电的时间等，具体来说知晓扭转力的范围就能明确扳手可适用的拆卸的螺母大小和类型，
The parameters of the wrench are the primary node to be concerned, which directly determines the working performance of the wrench. The parameters of the electric wrench mainly include power, large torsional force, small torsional force, battery capacity, and charging time. Specifically, knowing the range of torsional force can determine the size and type of nuts that can be removed by the wrench,

二、看扳手材料选购电动扳手时，第二个要关注的要点便是机体材料的选用，市面上常见电动扳手的材料一般采用橡胶与铁制品结合，弊端在于容易生锈或老化，若能选择高硬度、耐腐蚀、耐磨的材质，显然能增加工作效率，提高使用寿命和延展性。，钨钢的转轴和全铝的机头，使得电扳手具有高强度的耐腐蚀性、耐磨性，即使处于高温环境，扳手也能保持不变的质量。
2、 The second key point to pay attention to when selecting and purchasing electric wrenches is the selection of body materials. The common materials of electric wrenches on the market are generally rubber and iron products. The disadvantage is that they are easy to rust or age. If you can choose materials with high hardness, corrosion resistance and wear resistance, it will obviously increase work efficiency, improve service life and ductility., Tungsten steel shaft and all aluminum head make the electric wrench have high strength corrosion resistance and wear resistance. Even in high temperature environment, the wrench can maintain the same quality.
三、看与售后不管是选购电动扳手，还是其他商品，和售后也是需要关注的重要要点。选购具有的扳手，不仅是它质量的保证，也意味着在未来的使用过程中，一旦电动扳手出现异常，也能轻松问题。
3、 Brand and after-sales are also important points to pay attention to, whether it is to buy electric wrenches or other goods. The purchase of a brand wrench is not only a guarantee of its quality, but also means that in the future use process, once the electric wrench is abnormal, it can also easily solve the problem.
