Abstract

The invention discloses a handheld polishing device. The handheld polishing device comprises a fixed body, a movable cylinder and a collecting cylinder, wherein the collecting cylinder is connected to the upper end of the fixed body, a channel is formed on the fixed body; a driving motor is mounted in the fixed body, an output end of the driving motor is connected with a rotating shaft, the lower end of the rotating shaft is connected with a sand wheel, a plurality of blades are further arranged on the rotating shaft; an annular groove is formed in the inner wall surface of the movable cylinder, a positioning ring is arranged on the outer wall surface of the fixed body, an elastic part is arranged in the annular groove, the inner wall surface of the top of the annular groove is propped against the upper end surface of the positioning ring by the aid of the elastic part; a protective cover surrounding the sand wheel is arranged at the bottom end of the movable cylinder. With the arrangement of the protective cover and the blades, dust can be effectively prevented from flying apart all around, the influence on the surroundings is reduced, and the body health of an operator is guaranteed.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to a hand-held grinding device. Background technique [0002] In the process of metal processing, it is necessary to remove the rust on the metal surface. Especially before painting or welding, in order to ensure the normal progress of the painting and welding process and avoid the problems that the paint cannot be effectively attached and the strength of the weld is low, the metal surface must be derusted. At present, the quickest way to remove rust is to remove the rust on the metal surface by grinding. When grinding, the surface is mainly polished by the staff holding the grinding machine. During the grinding process, a large amount of dust will be generated, and the dust will permeate the air, causing extremely bad impact on the surrounding environment and seriously endangering the health of the staff. Contents of the invention [0003] The purpose of the present invent...
