The present invention discloses a driving device for a belt axle of a winch in the field of mechanics, which addresses the problems existing in conventional winches, for example the driving devices being out of work attributing to wearing of the unidirectional teeth on 5 the fixed base and rotary body of the winch. The driving device for the belt axle of the winch is positioned at the end of the belt axle of the winch. The driving device includes a fixed base and a rotary cylinder. Said rotary cylinder is provided with insertion holes into which a crow bar could be inserted. The fixed base is fixedly connected with the belt axle of the winch. Said rotary cylinder is covered on the fixed base and fixed thereto in the 10 axial direction. A unidirectional mechanism is located between the rotary cylinder and the belt axle to be engaged by unidirectional teeth. The belt axle would continuously rotate in one single direction by means of the said unidirectional mechanism while said rotary cylinder rotates to and fro. In the driving device of the invention, as the shift element and shift plates could be conveniently removed, the worn shift plates or shift element could be 15 conveniently replaced after being used for a long period.
