Under this working principle, the rotating worm 402 drives the worm wheel 4011 to rotate, and then the worm wheel 4011 further drives the first screw rod 405 to rotate. With the rotation of the first screw rod 405, the bearing 4010 driven by its lower end can move up and down, so that the coating roller 409 between the bearings 4010 also moves up and down.
