A belt 9 is provided, and a cleaning plate is fixedly connected to the outer surface of one end of the hollow cylinder 11 away from the fixed seat 1, and a cleaning cloth 12 is provided on the outer surface of the cleaning plate. In this embodiment, the motor 4 is turned on, and the motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first transmission wheel 7 thereon to rotate, and under the action of the first belt 9, another first transmission wheel 7 is driven to rotate, so that the hollow cylinder 11 is rotated. When the hollow cylinder 11 rotates, it drives the cleaning plate to rotate, so that the cleaning cloth 12 is rotated, and the paint microparticles on the surface of the protective cover 2 are wiped off by the cleaning cloth 12 to avoid the paint microparticles affecting the spraying vision of the staff due to long-term use.

[0024] The inner surface of the left connecting seat 3 is rotatably connected with a rotating rod, and the outer surfaces of the rotating rod and the hollow cylinder 11 are fixedly sleeved with a second transmission wheel 8, and a second belt 10 is wound around the outer surfaces of the two second transmission wheels 8. The outer surfaces of the rotating shaft 5 and the rotating rod are fixedly connected with fan blades 6. The outer surface of the protective cover 2 is provided with two air suction holes 13, and the outsides of the two air suction holes 13 are provided with filter nets. The two air suction holes 13 are respectively connected with the interiors of the two connecting seats 3. In this embodiment, when the hollow cylinder 11 rotates, it drives the second transmission wheel 8 thereon to rotate. When the second transmission wheel 8 rotates, it drives the other second transmission wheel 8 to rotate under the action of the belt, so that the rotating rod and the rotating shaft 5 rotate at the same time, and then the fan blades 6 rotate, and suction is generated from the air suction holes 13, further avoiding the diffusion of paint microparticles.

[0025] The inner surface of the fixed base 1 is rotatably connected with a forward and reverse screw rod 14, which rotates and penetrates the left outer surface of the fixed base 1, and the left outer surface of the forward and reverse screw rod 14 is fixedly connected with a knob 15. The outer surface of the forward and reverse screw rod 14 is threadedly connected with two threaded blocks 16, and the bottom outer surfaces of the two threaded blocks 16 are fixedly connected with an arc clamping plate 17. In this embodiment, the knob 15 is rotated, and the knob 15 drives the forward and reverse screw rod 14 to rotate. When the forward and reverse screw rod 14 rotates, the two threaded blocks 16 move towards each other, so that the two arc clamping plates 17 clamp the paint tube.

[0026] The cleaning plate is an elastic plate, and the outer surface of the cleaning plate is provided with a Velcro fleece surface, and the outer surface of the cleaning cloth 12 opposite to the cleaning plate is provided with a Velcro thorn surface. In this embodiment, the cleaning cloth 12 is tightly fitted to the surface of the protective cover 2 through the elastic cleaning plate, and the cleaning cloth 12 is fixed to the cleaning plate through the cooperation of the Velcro fleece surface and the Velcro thorn surface, so that the cleaning cloth 12 is easy to replace.

[0027] Through holes are provided on the outer surfaces of both the front and rear sides of the fixing seat 1. The inner diameter of the hollow cylinder 11 is larger than the inner diameter of the rear through hole. In this embodiment, the through hole provides a spraying channel for the paint tube.

[0028] The protective cover 2 and the fixing base 1 are both transparent. In this embodiment, the transparent protective cover 2 and the fixing base 1 are provided to facilitate the user to observe the spraying situation.

[0029] The bottom outer surfaces of the two arc-shaped clamping plates 17 are fixedly connected with sliders, the inner surface of the fixed seat 1 is fixedly connected with a sliding rod, and the two sliders are movably mounted on the outer surface of the sliding rod. In this embodiment, when the forward and reverse screw rods 14 rotate, the two arc-shaped clamping plates 17 are driven to move, so that the sliders slide on the outer surface of the sliding rod, preventing the arc-shaped clamping plates 17 from rotating with the rotation of the forward and reverse screw rods 14.

[0030] Working principle: When the utility model is in use, the spray tube for spraying paint is passed through the through hole of the fixing seat 1, and is placed on the protective cover 2 through the hollow cylinder 11. The knob 15 is turned, and the knob 15 drives the positive and negative screw rods 14 to rotate. When the positive and negative screw rods 14 rotate, the two threaded blocks 16 move in a direction close to each other, so that the two arc-shaped clamping plates 17 clamp the paint tube, and then the spraying work is carried out. When the spraying work is carried out, the paint particles generated during the spraying are protected by the protective cover 2. The motor 4 is turned on, and the motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the first transmission wheel 7 thereon to rotate, and under the action of the first belt 9, drives another first transmission wheel 7 to rotate. A transmission wheel 7 rotates, thereby causing the hollow cylinder 11 to rotate. When the hollow cylinder 11 rotates, the cleaning plate is driven to rotate, thereby causing the cleaning cloth 12 to rotate. The paint particles on the surface of the protective cover 2 are wiped off by the cleaning cloth 12 to avoid the paint particles affecting the spraying vision of the staff due to long-term use. When the hollow cylinder 11 rotates, the second transmission wheel 8 on it is driven to rotate. When the second transmission wheel 8 rotates, it drives another second transmission wheel 8 to rotate under the action of the belt, so that the rotating rod and the rotating shaft 5 rotate at the same time, and then the fan blades 6 rotate, and suction is generated from the air suction hole 13, further avoiding the diffusion of paint particles. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
