[0026] In this embodiment, by starting the self-locking motor 601 to rotate forward (at this time the one-way bearing 703 does not transmit), the rotating shaft 602 and the grinding disc 603 are driven to rotate and complete the grinding operation. Synchronously, the rotating shaft 602 drives the first bevel gear 604, the second bevel gear 605, the rotating rod 606, the first pulley 608, the second pulley 610, the driving rod 609, and the fan blade 611 to rotate and complete the heat dissipation operation of the self-locking motor 601.
