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 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 inconvenience to the grinding work.
