Description

Technical field

[0001] The invention relates to the technical field of electric tools, in particular to a chip removal device for electric tools. Background technique

[0002] In the 1960s, with the development of battery manufacturing technology, battery-type power tools without power cords that used nickel-cadmium batteries as power sources appeared. But at that time, development was slow due to high prices. In the mid-to-late 1970s, due to lower battery prices and shorter charging times, this power tool was widely used in Europe, America and Japan. Electric tools were originally made of cast iron, and later changed to aluminum alloy. In the 1960s, thermoplastic engineering plastics were applied to power tools, and double insulation of power tools was realized, which ensured the safety of power tools. Due to the development of electronic technology, electronic speed control power tools also appeared in the 1960s. This kind of electric tool uses thyristor and other component...
