Problems solved by technology

[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 sockets of the grinder are 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

Abstract

An improved type grinding device comprises an electric connecting seat and an electric connecting head. A torsion hole with a rightward opening portion is formed in the electric connecting seat. A torsion portion is rotationally installed in the torsion hole. Inserting holes penetrating through the torsion portion from left to right are formed in the torsion portion up and down correspondingly. Electric connecting sheets are fixedly installed in the inserting holes. A friction sheet is fixedly installed in the center of the left end surface of the torsion portion, and a round hole is formed inthe left end surface of the friction sheet. The part, located at the left end of the torsion hole, of the electric connecting seat is provided with an annulus groove. A middle groove is formed in thecenter of the left end of the annulus groove. A sliding pushing part is installed in the middle groove in a left-right moving mode. A fixed rod is fixedly installed in the center of the right end surface of the sliding pushing part. Semi-arc grooves located in the rear upper direction and front lower direction of the sliding pushing part are formed in the end wall of the annulus groove. Pushing grooves extending up and down are formed in the upper portion and the lower portion in the end wall of the annulus groove correspondingly and communicate with the semi-arc grooves. Electric connectingblocks are movably installed in the pushing grooves.
