A protective plate is located on the left side of the motor. A first limiting disc is fixedly fitted onto the right side of the rotating rod's surface. A grinding wheel disc is located on the left side of the first limiting disc and is fitted onto the rotating rod's surface. A second limiting disc is located on the left side of the grinding wheel disc and is fitted onto the rotating rod's surface. A threaded sleeve is fixedly connected to the left side of the second limiting disc, and the inner cavity of the threaded sleeve is threadedly connected to the rotating rod. Pushing components are located at the top and bottom of the protective plate's inner cavity. Each pushing component includes a sliding sleeve, the surface of which is fixedly connected to the protective plate's inner cavity. A push rod is movably connected to the surface of the sliding sleeve. A push plate is located on the left side of the push rod, and a handle is located on the right side. A threaded hole is formed on the surface of the push rod, and the inner cavity of the threaded hole... The threaded connection has a limiting rod, and a protective cover is provided on the left side of the protective plate. When the grinding wheel needs to be replaced, first loosen the fixing bolt. When the fixing bolt is removed from the protective cover, the protective cover can be removed from the protective plate. At this time, rotate the threaded sleeve. When the threaded sleeve moves out of the surface of the rotating rod, the second limiting plate can move out of the surface of the rotating rod along with the threaded sleeve. When the grinding wheel needs to be removed, rotate the limiting rod. When the limiting rod is removed from the threaded hole on the push rod, the push rod can move in the sliding sleeve. At this time, push the handle. The handle drives the push rod to move. The sliding sleeve moves in conjunction with the push rod. The push rod drives the push plate to move. The push plate can push the grinding wheel off the rotating rod. This makes it more convenient to remove the grinding wheel from the rotating rod, avoiding the inconvenience of having to hold the grinding wheel and pull it off by hand.
