The return mechanism 4 includes a first return elastic member connecting the first roller 1a and the base 6 and a second return elastic member connecting the second roller 1b and the base 6, the first return elastic member and the second return elastic member respectively driving the roller 1 in opposite directions to apply a return elastic force to the roller 1 driving the roller 1 toward a predetermined position in the first direction.
The elastic restoring component can be a spring, an elastic sheet piece or other components with restoring functions.
The first roller 1a and the second roller 1b are respectively located at two ends of the transmission belt 7 in the width direction of the transmission belt 7, when the transmission belt 7 deviates to one side, the transmission belt 7 presses the first roller 1a or the second roller 1b so as to enable the first roller 1a and the second roller 1b to deviate from preset positions, and the first roller 1a and the second roller 1b reset under the action of the elastic force of the resetting mechanism 4 and drive the transmission belt 7 to return to the normal positions.
