Abstract
A mechanism for slowing down idling shoe of an electric polisher is provided. The mechanism includes an actuating spindle that downward extends through a protective cover connected to a bottom of a housing of the polisher and has a lower end forming an eccentric shaft, a fixing seat that is mounted around the eccentric shaft of the actuating spindle and has a ball bearing fitted therein, a brake ring that has an elastic inner ring tightly fitted around a lower outer periphery of the fixing seat and an outer ring engaged with an underside of the protective cover, a shoe that is screwed to a bottom of the fixing seat for holding a polishing element to a bottom surface of the shoe. When the shoe is idling, the eccentric shaft of the actuating spindle brings the fixing seat to rotate synchronously in eccentric motion to increase a frictional force between the fixing seat and the brake ring, so that the idling shoe is brought to rotate at low speed and vibrate at high frequency.
