Abstract

A handheld polishing device comprises a rack. A containing cavity is formed in the rack. An empty slot is formed in the right end face of the rack. A clamping slot is formed in the upper end wall of the empty slot. A first power device is fixedly mounted in the upper end wall of the containing cavity. A rotating rod is connected on the first power device. A winding drum is fixedly mounted on the rotating rod. An electric wire is wound on the winding drum. A sliding pushing slot located below the containing cavity and extending up and down is further formed in the rack. A mounting cavity with the opening end facing the sliding pushing slot is formed in the rotating rod. A power connecting pin is fixedly mounted in the mounting cavity. The lower end of the power connecting pin penetrates into the sliding pushing slot. The top end of the electric wire penetrates into the mounting cavity and is fixedly connected with the power connecting pin. A sliding pushing block is mounted in the sliding pushing slot in the mode that the sliding pushing block can move up and down. An inserting slot matched with the power connecting pin is formed in the upper end face of the sliding pushing block. Pushing arms are arranged on the left and right sides of the upper end face of the sliding pushing block correspondingly.

Description

technical field [0001] The invention relates to the technical field of workpiece grinding, in particular to a hand-held grinding device. Background technique [0002] In some workpiece processing factories, grinding devices are often used to polish and polish the surface of workpieces to increase smoothness. Hand-held grinding machines are widely used because of their small size, high speed, good stability, single-handed operation, not easy to fatigue, and fine-grained workpieces. However, in the existing technology, due to the long power supply line of the hand-held grinder, it is extremely difficult to retract and easy to be affected by external factors such as trampling and dragging, so that the skin of the power supply line is damaged, resulting in a decrease in service life. disadvantages. Contents of the invention [0003] The object of the present invention is to provide a hand-held grinding device and its usage method, which can overcome the above-mentioned defec...
