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 wide 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、 See 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，以电扳手为例，扭矩差值达到300扭米，意味着不管是起拧螺丝，还是架子安装，甚是拆卸轮胎都能轻松。电扳手电池容量为4安时，大容量的电池能持久续航，恒功输出，扭力不减，保障作业进度。
The parameters of the wrench are the primary nodes that need to be paid attention to, which directly determines the working performance of the wrench. The parameters of the electric wrench mainly include power, large torque, small torque, the capacity of the battery, and the time to charge. Specifically, knowing the range of torque can determine the size and type of nuts that the wrench can be used to disassemble. Taking the electric wrench as an example, the torque difference reaches 300 torque meters, which means that it can be easily solved whether it is screwing, installing the rack, or even disassembling the tire. When the battery capacity of the electric wrench is 4 A, the high-capacity battery can last for a long time, with constant power output and constant torque, so as to ensure the operation progress.
二、看扳手材料选购电动扳手时，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。还是以电扳手为例，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、 When looking at wrench materials to choose electric wrenches, the second key point to pay attention to is the selection of body materials. The materials of common electric wrenches in the market generally use the combination of rubber and iron products. The drawback is that they are easy to rust or age. If you can choose materials with high hardness, corrosion resistance and wear resistance, it can obviously increase work efficiency and improve service life and ductility. Taking the electric wrench as an example, the tungsten steel rotating shaft and the all aluminum head make the electric wrench have high-strength corrosion resistance and wear resistance, and the wrench can maintain the same quality even in a high-temperature environment
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。而电扳手依托强大的背景，以生产工具20余年的形象提出了终身保用的售后服务，让用户能用得放心。电动扳手不仅仅在拆卸与安装电动车和摩托车的零部件方面大大提高了工作效率，同时在汽车、建筑等行业也担任着重要的角色，对于这样一款功能多样化的电动工具，不妨看看电扳手，或许能带来不错的体验。
3、 Look at the brand and after-sales. Whether it is the purchase of electric wrenches or other commodities, the brand and after-sales are also important points that need to be paid attention to. Choosing a brand wrench is not only the guarantee of its quality, but also means that in the future, once the electric wrench is abnormal, it can easily solve the problem. Relying on the strong background, the electric wrench has put forward the after-sales service of lifelong warranty with the image of professional production tools for more than 20 years, so that users can feel at ease. The electric wrench not only greatly improves the work efficiency in disassembling and installing the parts of electric vehicles and motorcycles, but also plays an important role in the automotive, construction and other industries. For such a versatile electric tool, you might as well take a look at the electric wrench, which may bring a good experience.
