[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 The utility model includes a vertical connecting plate 1, a shell 2 with an opening facing right is fixed on the right side of the connecting plate 1, a vertical vertical shaft 3 that can be actively rotated is arranged in the shell 2, a first worm gear 5 is arranged at both ends of the vertical shaft 3, wherein the first worm gear 4 is coaxially fixed with the vertical shaft 3, and the first worm gear 5 is rotatably mounted on the shell 2, a hanging basket 6 is arranged on the right side of the shell 2, a cross bar 7 corresponding to the first worm gear 5 is hinged on the hanging basket 6, and the left end of the cross bar 7 is fixed to the first worm gear 5 corresponding to the first worm gear 5, and the shell 2, two first worm gears 5, two cross bars 7 and the hanging basket 6 are arranged. A parallelogram structure is formed; when the vertical rod rotates, the vertical rod drives the first worm wheel 5 to rotate through the first worm gear 4, and then drives the steel cage to swing up and down through the cross bar 7; a rotatable second worm wheel 8 is set in the middle of the vertical shaft 3, a second worm gear 9 is arranged on the left side of the second worm gear 8, and a U-shaped plate 10 with an opening facing right is fixed to the right end of the second worm gear 9, a plurality of vertical connecting rods 11 are arranged in the U-shaped plate 10, and the ends of the connecting rods 11 are hinged to the corresponding cross bars 7; the second worm wheel 8 drives the plurality of connecting rods 11 to swing back and forth through the U-shaped plate 10, thereby realizing the swinging of the hanging basket 6 back and forth.
