电动扭剪扳手顾名思义就是扭剪梅花头螺栓拧紧作业的一定工具，帮助您装、拆螺拴、螺母，同时能比较准确地控制拧紧扭矩。利用螺栓定扭矩，当扳手达到一定扭矩时即可剪断螺栓的梅花头部分，其扭矩精度和轴向拉力是靠螺栓的定扭矩V型切口来保证的。拆装扭力矩大、比手工更保险可靠。方便、美观、实用、便于随车携带，广泛用于钢结构桥梁、厂房、发电设备等设施的施工作业。
As the name suggests, the electric wrench is a tool for tightening the box head bolts. It can help you install and remove the bolts and nuts, and control the tightening torque accurately. When the wrench reaches a certain torque, the quincunx head of the bolt can be cut. The torque accuracy and axial tension are guaranteed by the V-shaped notch of the bolt. The torque of disassembly and assembly is large, which is more safe and reliable than manual operation. It is convenient, beautiful, practical and easy to carry with the car. It is widely used in the construction of steel structure bridges, workshops, power generation equipment and other facilities.
近年来，随着电动扭剪扳手的应用需求逐渐增 大，市面上兴起了一大批电动扭剪扳手厂家，但是许多人并不了解如何选择合适的厂家，今天小编来详细的讲解一下。
In recent years, with the increasing demand for the application of electric torque wrench, a large number of electric torque wrench manufacturers have sprung up in the market, but many people don't know how to choose the right manufacturer. Today, let's make a detailed explanation.
1.上的比较，每个厂家生产的电动扭剪扳手都存在一定差异，我们需要查看哪个厂家更具性价比，选择高性价比的厂家。
1. Compared with the price, there are some differences in the price of the electric torsion shear wrench produced by each manufacturer. We need to check which manufacturer is more cost-effective and choose the one with high cost performance.
2.在材质上进行对比，购买电动扭剪扳手时可以根据需要购买的数量和规格来选择，但材质的选择也是非常重要的，如果选择的材质较差，则电动扭剪扳手的成品质量也不佳。
2. In terms of material comparison, when purchasing electric torsion shear wrench, you can choose according to the quantity and specification you need to buy, but the choice of material is also very important. If the selected material is poor, the finished product quality of electric torsion shear wrench is also poor.
3.查看电动扭剪扳手厂家以往的合作客户数量，这可以从侧面反映厂家的服务态度和实力。
3. Check the number of cooperative customers of the electric wrench manufacturer in the past, which can reflect the service attitude and strength of the manufacturer from the side.
4.了解电动扭剪扳手厂家的加工机械和设备，设备的完整性决定了厂家的生产能力以及电动扭剪扳手的质量。
4. Understand the processing machinery and equipment of the electric torque wrench manufacturer. The integrity of the equipment determines the production capacity of the manufacturer and the quality of the electric torque wrench.
5.确定电动扭剪扳手厂家是否具有完善的售后服务。尽管在运输过程中电动扭剪扳手不容易损坏，但是如果存在细节上的质量问题，还是需要厂家能够协商，因此找到一家售后服务好的厂家也是非常重要的。
5. Determine whether the electric wrench manufacturer has perfect after-sales service. Although the electric wrench is not easy to be damaged during transportation, if there are quality problems in details, it still needs to be solved by the manufacturer through negotiation. Therefore, it is very important to find a manufacturer with good after-sales service.
