市場電扳手琳瑯滿目，若是硬要推薦一款，或許有失偏頗，其實(shí)挑選一款高質(zhì)量的合適的電扳手只需把握幾種要素。
There are a wide range 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(shù)；扳手的參數(shù)是需要關(guān)注的首要節(jié)點(diǎn)，直接決定了扳手的工作性能。
1、 See the wrench parameters; The parameters of the wrench are the primary node that needs attention, which directly determines the working performance of the wrench.
二、看扳手材料選購電動(dòng)扳手時(shí)，另一個(gè)要關(guān)注的要點(diǎn)便是機(jī)體材料的選用，市面上常見電動(dòng)扳手的材料一般采用橡膠與鐵制品結(jié)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(zhì)，顯然能增加工作效率，提高使用壽命和延展性。
2、 When looking at wrench materials, another key point to pay attention to when purchasing electric wrenches is the selection of body materials. The materials of common electric wrenches on the market generally use the combination of rubber and iron products. The disadvantage is that they are easy to rust or aging. 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.
三、看與售后不管是選購電動(dòng)扳手，還是其他商品，和售后也是需要關(guān)注的重要要點(diǎn)。選購具有的扳手，不僅是它質(zhì)量的保證，也意味著在未來的使用過程中，一旦電動(dòng)扳手出現(xiàn)異常，也能輕松解決問題。
3、 Look at the brand and after-sales. Whether it is to buy electric wrenches or other goods, the brand and after-sales are also important points to pay 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.
終緊扭剪型高強(qiáng)螺栓需要用扭剪型高強(qiáng)螺栓扳手，因?yàn)榕ぜ粜透邚?qiáng)螺栓的終緊一定要把它的梅花頭打斷，只有扭剪型高強(qiáng)螺栓扳手才能。 高強(qiáng)螺栓的緊固需要先初緊再終緊，扭剪型高強(qiáng)螺栓的初緊可以選擇沖擊電動(dòng)扳手、定扭矩電動(dòng)扳手或扭剪型電動(dòng)初緊扳手，并且一般達(dá)到終緊扭矩的50-60%就可以了。
The final tightening of torsional shear high-strength bolt requires torsional shear high-strength bolt wrench, because the final tightening of torsional shear high-strength bolt must break its plum blossom head. Only torsional shear high-strength bolt wrench can. The tightening of high-strength bolts requires initial tightening before final tightening. The initial tightening of torsional shear high-strength bolts can choose impact electric wrench, constant torque electric wrench or torsional shear electric initial tightening wrench, and generally it can reach 50-60% of the final tightening torque.
扭剪型高強(qiáng)螺栓扳手產(chǎn)品特點(diǎn)：
