ABSTRACT:
A turning disc intermittent rotary mechanism in accordance with the invention includes at least one top disc flexibly mounted to a bottom seat, wherein at the center of the top disc is provided with a through hole and the bottom surface thereof is provided with sliding slots; and a main driving wheel flexibly mounted to the bottom seat using a round through hole provided in advance, wherein at the side of the upper surface of the main driving wheel is provided with a small pulley that is disposed in the sliding slots and is capable of sliding. Consequently, the force produced by the small pulley acting at the long sliding slot thereof is effectively reduced, thereby lengthening the lifespan of the force transmission mechanism including the small pulley and the main driving wheel.
