An installation cylinder 5 is fixedly connected inside the cylindrical spray booth 3. Telescopic installation rods 4 are fixedly connected inside the installation cylinder 5 and on the upper inner wall of the box body 1. The upper end of the telescopic installation rod 4 inside the installation cylinder 5 penetrates the upper surface of the installation cylinder 5. The telescopic installation rod 4 consists of a spring 9 and a round rod 10. One end of the round rod 10 is fixedly connected to the spring 9, and the end of the round rod 10 away from the spring 9 is fixedly connected to the clamp 6. The telescopic installation rod 4 is used to apply two opposing forces, one above and one below, to the steel structure. A protective sleeve 7 is provided at the upper end of the installation cylinder 5. The protective sleeve 7 has a conical structure, and the upper end of the protective sleeve 7 is in close contact with the surface of the upper end of the telescopic installation rod 4 located below. The protective sleeve 7 is used to increase the difficulty for paint to enter the interior of the installation cylinder 5.

[0024] Furthermore, clamps 6 are fixedly connected to the upper and lower ends of the two telescopic mounting rods 4. When the device is in use, the two clamps 6 are in close contact with the upper and lower ends of the steel structure. The clamps 6 are composed of a positioning plate 11, a limiting plate 12, and bolts 13. When the device is in use, the positioning plate 11 and the limiting plate 12 clamp the steel structure. The positioning plate 11 is fixedly connected to the round rod 10. The bolts 13 pass through the limiting plate 12 and are rotatably connected to the limiting plate 12.

[0026] Working principle: When adding the steel structure, the upper clamp 6 is used to fix the steel structure first. Then, the lower telescopic mounting rod 4 is pulled up and the lower clamp 6 is used to hold the lower end of the steel structure. Then, the tension applied to the lower telescopic mounting rod 4 is released. At this time, the spring 9 returns to its original position after the external force is no longer affected. The two springs 9 are then fixed in a state of tension and balance, which improves the stability of the steel structure during the spraying process. During the spraying process, excess paint falls to the bottom of the cylindrical spraying chamber 3 due to gravity. The paint at the bottom of the cylindrical spraying chamber 3 enters the collection drawer 8 through the guide groove 16 and the falling through hole 17. The heat insulation pad 15 at the sliding part of the collection drawer 8 reduces the solidification of the collected paint due to cooling.
