市場電扳手琳瑯滿目，若是硬要一款，或許有失偏頗，其實挑選一款高質量的合適的電扳手只需把握幾種要素。
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、看扳手參數
1、 See wrench parameters
扳手的參數是需要關注的首要節點，直接決定了扳手的工作性能。電扳手的參數主要包括功率、大扭轉力、小扭轉力、電池的容量大小、以及需要充電的時間等，具體來說知曉扭轉力的范圍就能明確扳手可適用的拆卸的螺母大小和類型，以電扳手為例，扭矩差值達到300扭米，意味著不管是起擰螺絲，還是架子安裝，甚是拆卸輪胎都能輕松。電扳手電池容量為4安時，大容量的電池能持久續航，恒功輸出，扭力不減，保障作業進度。
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、看扳手材料選購電動扳手時，二個要關注的要點便是機體材料的選用，市面上常見電動扳手的材料一般采用橡膠與鐵制品結合，弊端在于容易生銹或老化，若能選擇高硬度、耐腐蝕、耐磨的材質，顯然能增加工作效率，提高使用壽命和延展性。還是以電扳手為例，鎢鋼的轉軸和全鋁的機頭，使得電扳手具有高強度的耐腐蝕性、耐磨性，即使處于高溫環境，扳手也能保持不變的質量
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、看與售后不管是選購電動扳手，還是其他商品，和售后也是需要關注的重要要點。選購具有的扳手，不僅是它質量的保證，也意味著在未來的使用過程中，一旦電動扳手出現異常，也能輕松問題。而電扳手依托強大的背景，以生產工具20余年的形象提出了終身保用的售后服務，讓用戶能用得放心。電動扳手不僅僅在拆卸與安裝電動車和摩托車的零部件方面大大提高了工作效率，同時在汽車、建筑等行業也擔任著重要的角色，對于這樣一款功能多樣化的電動工具，不妨看看電扳手，或許能帶來不錯的體驗。
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.
