Abstract
A transmission device includes a mounting frame having an abutting member, a driving sleeve sleeved fixedly on a drive shaft extending through the base plate, a transmission wheel sleeved rotatably on the driving sleeve, and a connecting post extending through a radially extending through hole in the transmission wheel and into a spiral first guiding groove in the driving sleeve having opposite first and second ends. A position-limiting member is disposed rotatably on a side surface of the transmission wheel. A ball is disposed in a ball-receiving hole in the position-limiting member and is movable in a curved second guiding groove in the side surface of the transmission wheel having a shallower first end and a deeper second end. When the drive shaft rotates regularly and reversely, the ball is spaced apart from the abutting member.
