A first groove 705 is provided inside the outer side of the first fixed plate 701, and a first support plate 706 is provided on the inner side of the first groove 705. The connection between the first support plate 706 and the rotating plate 703 is a fixed connection. The appearance and structural shape of the first support plate 706 is circular, and the cooperation between the first support plate 706 and the first groove 705 is a clearance fit, so that the first support plate 706 will not shake when rotating on the inner side of the first groove 705.
