Multifunctional sander

Abstract

The multifunctional sander includes a casing, a driving element with motor shaft, an eccentric device matched with the motor shaft and a base plate matched with the eccentric device, and has also a braking unit connected elastically to the casing and a converting unit capable of shifting relatively to the casing. By means of increasing the converting unit and changing the matching relation between the braking unit and the base plate, the present invention can realize both circular grinding function and plate grinding function. The multifunctional sander has less parts, simple structure, low cost, convenient switching between different grinding modes and less vibration.

Description

Technical field [0001] The invention relates to a multifunctional hand-held electric grinding tool. Background technique [0002] Existing sanding machines include circular sand and plate sand, etc., wherein the grinding base plate of circular sand can perform eccentric rotation movement relative to the motor shaft, and the grinding base plate does irregular orbital motion, which is used for grinding a large amount of materials; plate sand The grinding base plate can not make eccentric rotation movement relative to the motor shaft, therefore, the grinding base plate can only do regular orbital movement, which is suitable for grinding small amount of material, such as for fine machining or finishing. If the user wants to have two processing capabilities of fine grinding and fine grinding, he must purchase two tools, a circular sand machine and a flat sand machine. [0003] And U.S. Patent US6132300 disclosed a kind of two-function sanding machine in October, 2000, and this s...
