[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the support frame 1 has an internal movable groove 2, and a lifting mechanism 3 is installed on the top of the support frame 1. The lifting mechanism 3 includes a frame plate 31 fixedly installed on the top of the support frame 1. A drive motor 32 is fixedly connected to the top of the frame plate 31. The output shaft of the drive motor 32 is fixedly connected to a rotating rod 33 through a coupling. A first gear 34 is fixedly connected to one end of the rotating rod 33. A second gear 35 is movably connected to the outer wall of the first gear 34. A threaded rod 38 is movably connected to the inside of the second gear 35. A receiving plate 4 is fixedly connected to the outer wall of the threaded rod 38. A guide rod 5 is fixedly connected to the top of the receiving plate 4. A threaded groove 36 is opened inside the second gear 35. A retaining ring 37 is fixedly connected to the bottom of the second gear 35. The first gear 34 and the support frame 1 form a rotating structure through the rotating rod 33. The first gear 34 and the second gear 35 are meshed and connected. The retaining ring 37 forms a rotating structure with the support frame 1 through the movable groove 2. The second gear 35 is threadedly connected to the threaded rod 38 through the threaded groove 36. The guide rod 5 and the support frame 1 form a sliding structure.

[0031] By starting the drive motor 32, the rotating rod 33 can be rotated, which drives the first gear 34 to rotate. Since the first gear 34 is meshed with the second gear 35, the second gear 35 can be rotated. Since the second gear 35 is threadedly connected to the threaded rod 38 through the threaded groove 36, the threaded rod 38 can slide along the support frame 1, which drives the guide rod 5 fixedly connected to the top of the receiving plate 4 to slide along the support frame 1, thereby driving the painting rack 9 installed at the bottom of the threaded rod 38 to rise and fall.

[0032] Reference Figure 1 , Figure 4 and Figure 5 As shown, the threaded rod 38 has a positioning slot 6 inside, and a first half-threaded post 7 is fixedly connected to the outer wall of the threaded rod 38.

A second half-threaded post 11 is fixedly connected to the outer wall of the painting frame 9. A nut 8 is installed on the outer wall of the first half-threaded post 7. The threaded rod 38 is engaged with the positioning block 10 through the positioning slot 6. The first half-threaded post 7 and the second half-threaded post 11 are adapted to each other. The first half-threaded post 7 is threadedly connected to the nut 8, and the second half-threaded post 11 is threadedly connected to the nut 8.

[0033] By rotating the nut 8, which is threadedly connected to the first half-threaded post 7 and the second half-threaded post 11 respectively, the nut 8 can be disassembled and the limiting position on the first half-threaded post 7 and the second half-threaded post 11 can be released. Pulling down the painting frame 9 can move the positioning block 10 out of the positioning slot 6, allowing the painting frame 9 to be disassembled and maintained. By moving the painting frame 9, the positioning block 10 is engaged and engaged in the positioning slot 6, causing the first half-threaded post 7 and the second half-threaded post 11 to combine into a complete threaded post. Then, by engaging the nut 8 with one end of the threaded post and rotating it, the painting frame 9 can be limited and installed.
