Commonly used electric tool repair

The power tool is a hand-held or portable mechanized tool that uses a small-capacity motor or electromagnet to drive a work head through a transmission mechanism. The power tool has the advantages of simple structure, light weight, convenient carrying, and easy maintenance. The use of power tools can increase labor productivity several times to several times as much as manual tools, and has obvious effects on reducing labor intensity, improving working conditions and improving processing quality. Therefore, power tools are widely used in various sectors of the national economy, and their development prospects are very broad.
