Novel polishing device

Abstract

The invention provides a novel polishing device. The novel polishing device comprises an electric connection seat and an electric connector, wherein a twisting hole with a rightward mouth part is formed in the electric connection seat, a twisting part is rotatably mounted in the twisting hole, inserting holes penetrating from left to right are formed in the twisting part correspondingly up and down, and electric connecting pieces are fixedly mounted in each inserting hole; a friction piece is fixedly mounted at the center of a left end face of the twisting part, and a circular hole is formed in a left end face of the friction piece; and an annular slot is formed in a part, located at the left end of the twisting hole, of the electric connection seat, a middle slot is formed in the center of the left end of the annular slot, the middle slot is provided with a sliding component in a left-and-right movable manner, a fixed rod is fixedly mounted at the center of a right end face of the sliding component, semi-arc slots located above the back of the sliding component and located below the front of the sliding component are formed in an end wall of the annular slot, pushing slots extending up and down are formed in the end wall of the annular slot correspondingly up and down, the pushing slots are communicated with the semi-arc slots, and electric connection blocks are movably mounted in the pushing slots.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a novel grinding device. Background technique [0002] In some workpiece processing factories, hand-held grinders are often used to grind and polish the surface of the workpiece. The hand-held grinder can only perform grinding work after the power supply is plugged in. Traditionally, the electric connector of the grinder is generally connected to the mains. The internal conductive sheet is set relatively outside, which may cause electric shock accidents if accidentally touched by humans, and there is a large safety hazard. The friction between them is used to achieve the locked state, but this locking method is extremely unstable. After plugging, it is very easy to be affected by dragging and pulling the power supply line, resulting in loose plugging, which interrupts the power supply and brings great damage to the grinding work. inconvenient.
