[0038] A rotating shaft 34 is fixedly connected to the top center of the rotating plate 3, and a driving assembly 4 for driving the rotating shaft 34 to rotate is provided on the inner rear wall of the box body 2;

[0039] A winding shaft 5 is rotatably connected between the left and right inner walls of the box body 2, and two limit plates 51 are symmetrically fixedly connected to the outer wall of the winding shaft 5. A second motor 6 is fixedly connected to the right side of the outer wall of the box body 2, and the output shaft of the second motor 6 is fixedly connected to the right end of the winding shaft 5.

[0041] A driven gear is fixedly connected to the upper side of the outer wall of the rotating shaft 34, and the driven gear is meshed with the driving gear 42 for transmission;

[0042] A lifting plate 7 is slidably connected between the left and right inner walls of the box body 2;

[0043] A notch plate 71 is fixedly connected to the front side of the lifting plate 7. A notch is formed at the front end of the notch plate 71. The notch plate 71 is located directly below the winding shaft 5.

[0044] An upper blocking plate 72 is fixedly connected to the bottom of the outer wall of the lifting plate 7, and a lower blocking plate 73 is fixedly connected to the top of the rotating plate 3, and the upper blocking plate 72 is in contact with the lower blocking plate 73;

[0045] A lifting assembly 8 for driving the lifting plate 7 to move up and down is provided on the right side of the outer wall of the box body 2;

[0046] The lifting assembly 8 includes a protruding plate 81 and a cylinder 82. The protruding plate 81 is fixedly connected to the right end of the lifting plate 7.
