shaft

2, and 2 one end fixed mounting of driving shaft have driven

pulley

7, and 2 other end fixed mounting of driving shaft have driving

gear

4, and 1 both sides wall movable mounting of organism has driven

shaft

3, and 3 one end fixed mounting of driven shaft have driven gear 5, and driving gear 4 and driven gear 5 mesh, 1 bottom fixed mounting of organism has motor 8.

An output shaft of the motor 8 is fixedly provided with a driving belt wheel 6, the driving belt wheel 6 is in transmission connection with a driven belt wheel 7 through a belt 9, a V-shaped belt groove is formed in each of the driving belt wheel 6 and the driven belt wheel 7, and the belt 9 is a V-shaped belt.
