The two adjusting screws 7 on the transmission plate 6 drive the driving wheel 5 to rotate. Magnet fixing holes are provided on the opposite surfaces of the driving wheel 5 and the driven wheel 2 and magnets are embedded; the magnets embedded on the two wheels are attracted to each other; the driven wheel 2 is installed on the transmission shaft 8 via the bearing 4.
