Therefore, the first guide wheel and the second guide wheel are abutted against the guide rail, and the guide of the third transmission rail 11 during up-down lifting is realized. In the present embodiment, the first guide wheel and the second guide wheel are both disposed on the third transmission rail 11 through bearings.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
