[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a spraying assembly to connect an external pipe to an inlet pipe. The paint enters the annular channel through the external pipe and the inlet pipe, and is sprayed onto the surface of the cylindrical structure by multiple nozzles. A rotating component drives a gear to rotate. Since the gear meshes with the toothed ring, the rotating ring rotates along the inner side of the lifting ring, causing the nozzle to rotate back and forth between 0° and 35°, making the spraying more uniform and comprehensive. A drive component drives a lead screw to rotate, and under the action of the threaded pair, the sliding sleeve slides along the length of the lead screw, thereby adjusting the height of the nozzle and spraying the surface of the cylindrical structure from all directions.

[0019] 2. This utility model, through the provision of a first fixing component and a second fixing component, places a cylindrical object on top of the first fixing component. Rotating the threaded rod causes it to press against the arc-shaped clamping plate, clamping the bottom of the cylindrical object. Then, rotating the threaded cylinder releases the restriction on the second fixing component. Adjusting the position of the second fixing component so that it abuts against the top of the cylindrical object, rotating the threaded rod again causes it to press against the arc-shaped clamping plate, clamping the top of the cylindrical object. Finally, rotating the threaded cylinder limits and fixes the second fixing component, facilitating the clamping of the cylindrical object. Attached Figure Description
