A chip removal device for an electric tool

Abstract

The invention relates to the technical field of electric tools, and discloses a chip removal device of an electric tool. The chip removal device comprises a U-shaped fixing plate, the inner walls of the left side and the right side of the U-shaped fixing plate are correspondingly and rotationally connected with a first screw rod and a second screw rod through ball bearings, threads of the wall ofthe first screw rod and the wall of the second screw rod are mutually opposite threads, one end of the first screw rod and one end of the second screw rod are welded together, a driven bevel gear is fixedly connected to the welding position in a sleeve mode, a through hole is formed in the upper end of the U-shaped fixing plate, a rotating rod is rotationally connected in the through hole througha ball bearing, a driving bevel gear meshed with the driven bevel gear is fixedly connected to the lower end of the rotating rod, an L-shaped handle is fixedly connected to the upper end of the rotating rod, and the L-shaped handle is clamped with the U-shaped fixing plate through a positioning mechanism. The chip removal device of the electric tool has the advantage of being suitable for rapid chip removal work of electric cutting tools with different sizes.

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 Electric tools were originally made of cast iron, and later changed to aluminum alloy.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...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a chip removal device for electric tools, which has the advantage of being applicable to electric cutting tools of different sizes for fast chip removal, and solves the problem of The problem of cutting produces a large amount of waste chips. The direct discharge of waste chips not only affects the health of the staff, but also greatly causes environmental pollution. It is not convenient for people to use electric cutting tools.
