[0018] 1. This utility model uses a first motor to drive a first gear to rotate, which in turn drives a second gear to rotate, thus causing a worm to rotate. Multiple worms drive corresponding worm wheels to rotate, thus causing multiple rotating rods to rotate, which in turn causes multiple first transmission wheels to rotate.
