[0002] Paint, traditionally known as paint in China, is a viscous liquid coated on the surface of an object to be protected or decorated, and can form a continuous film that is firmly attached to the object. It is usually a resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. Nowadays, fire-proof, rust-proof, and corrosion-resistant coatings are sprayed on the surface of steel components to increase the service life of steel components.

[0003] When a commonly used sprayer is in use, the paint is stirred and vibrated evenly, and then the paint is sprayed into the nozzle through the output pipe, and then sprayed onto the surface of the steel by the nozzle. Since the width of some rectangular steel components is small, the paint sprayed from the nozzle will splash around the component steel components, causing the paint to splash onto people or objects around. For this reason, paint splashing onto human skin will irritate the skin. When paint splashes onto objects, it is inconvenient to remove the paint, which affects the use of the objects. For this reason, a surface coating device is needed to facilitate shielding of the nozzle and reduce the amount of paint splashing outward. Summary of the invention
