[0047] As a further implementation of the present scheme, the bottom end of the pull rope 43 is fixedly connected with the upper end of the inclined block 451, the upper end of the pull rope 43 penetrates through the top end of the vertical plate 411, and the pull rope 43 is slidingly connected with the vertical plate 411, so that the stability of the pull rope 43 during the movement of the pull rope 43 is ensured.

[0048] As a further implementation of the present scheme, the upper end of the lifting unit 4 is welded with a take-up unit 5, and the take-up unit 5 comprises a take-up box 51 and a connecting shaft 52 rotatably connected in the take-up box 51, and a take-up disc 53 fixedly connected to the outer side of the middle of the connecting shaft 52, so that the pull rope 43 can be wound and unwound as needed.

[0049] As a further implementation of the present scheme, the winding box 51 is fixedly connected to the upper end of the vertical plate 411, the outer side of the winding disc 53 is wound with the pull rope 43, the outer side of the winding box 51 is fixedly connected with the synchronous motor 6, and one end of the connecting shaft 52 is exposed to the outer side of the winding box 51. The part of the connecting shaft 52 exposed to the outer side of the winding box 51 is fixedly connected between the main shaft of the synchronous motor 6.
