Abstract
The present invention relates to a two-way rotary multi-function polisher, which comprises an input shaft driven to rotate by a power resource, a first spur gear and a second spur gear engagably transmitted by the end of input shaft; wherein the first spur gear is in response to the second spur gear and fixed to an output shaft having an inner polishing disc at the end thereof, so as to rotate the inner polishing disc in the first direction, while the second spur gear is coupled to a sleeve having an outer polishing disc at the end thereof and disposed to the exterior of output shaft by a bearing, so as to rotate the outer polishing disc in the second direction; hence, while the input shaft rotating, the inner and the outer polishing disc can respectively rotate in the opposite direction, enabling the two-way polishing and grinding to be achieved.
