[0018] 2. In the present invention, when the worm rotates, it will drive the first wheel to rotate, and then drive the conveyor belt to rotate. The second wheel will rotate under the drive of the conveyor belt. When the second wheel rotates, it will drive the rotating shaft to rotate, and further drive the gear to rotate.

[0019] 3. The present invention drives the sliding column to move by sliding the connecting column. When the connecting column moves to the appropriate position, the connecting column is rotated so that it is fixed inside the shell through the second slide groove opened inside the shell.
