Referring to fig. 3, a guide plate 901 is fixedly connected to the lower end of an exhaust fan outer frame 9, the guide plate 901 is located on the upper side of a positioning clamp 25, when the exhaust fan outer frame 9 absorbs the exhaust gas generated after the paint spraying of the sprayer 5, in order to enable the exhaust fan outer frame 9 to collect the gas more quickly and efficiently, the guide plate 901 is additionally arranged to guide the suction force generated by the exhaust fan 10, so that the exhaust gas generated by the sprayer 5 can more quickly enter a filter pipe 11, the surface of the exhaust fan 10 is coated with a protective paint 1001, the protective paint 1001 is made of a grease material, when the exhaust fan 10 absorbs the paint mist generated after the paint spraying of the sprayer 5, the paint mist is attached to the surface of the exhaust fan 10, in order to facilitate the cleaning of the paint mist on the surface of the exhaust fan 10, the surface of the exhaust fan 10 can be uniformly coated with the protective paint 1001 for cleaning before the paint spraying, the inner wall of the filter pipe 11 is fixedly connected with a limiting ring, the limiting ring 1101 is positioned at the lower end of the main paint mist filter cotton 13, when the main paint mist filter cotton 13 is installed in the filter pipe 11, in order to limit the position of the main paint mist filter cotton 13 installed in the filter pipe 11, the limiting ring 1101 is additionally arranged to limit the position of the main paint mist filter cotton 13 placed in the filter pipe 11, and the main paint mist filter cotton 13 is not easy to block a connecting port between the air duct 12 and the filter pipe 11 due to too deep installation, two symmetrical fixed support columns 1301 are fixedly connected to the upper end of the main paint mist filter cotton 13, the fixed support columns 1301 are positioned at the lower end of the secondary paint mist filter cotton 14, the secondary paint mist filter cotton 14 is placed on the upper side of the main paint mist filter cotton 13 after the main paint mist filter cotton 13 is installed, in order to keep a certain space between the main paint mist filter cotton 13 and the secondary paint mist filter cotton 14, the main paint mist filter cotton 13 and the secondary paint mist filter cotton 14 can be separated by the fixed support columns 1301, can make inferior lacquer fog filter pulp 14 better carry out the secondary to the lacquer fog and adsorb, and when changing main lacquer fog filter pulp 13 and inferior lacquer fog filter pulp 14, can directly take out main lacquer fog filter pulp 13 after taking out inferior lacquer fog filter pulp 14, improve change efficiency.

Referring to fig. 4, the pull rings 1801 are fixedly connected to the left ends of the acid gas filter cloths 18 and 5N11, the pull rings 1801 are provided with anti-slip patterns on the surface, after the exhaust pipe 16 is installed at the outer end of the filter pipe 11, the acid gas filter cloths 18 and 5N11 need to be inserted into the insertion holes 17, so that the acid gas filter cloths 18 and 5N11 can be taken more conveniently and quickly by the pull rings 1801, and the acid gas filter cloths 18 and 5N11 can be taken more quickly by the pull rings 1801.

Referring to fig. 5, a cloth cover 2501 is sleeved on the outer end of the positioning clamp 25, magnetic powder is filled in the cloth cover 2501, and after the metal handicraft is placed on the positioning clamp 25, the metal handicraft can be adsorbed by the cloth cover 2501 to be more stable, so that the metal handicraft is not easy to shake on the positioning clamp 25 and is not easy to shift in position during rotation.

The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
