The bottom of the connecting pipe 3 passes through the spray gun 1 and extends to the bottom of the spray gun 1, and a material tank 4 is movably sleeved thereon. A fixing plate 5 is fixedly sleeved on the outer surface of the connecting pipe 3. A fixing block 6 is fixedly connected to the bottom of the fixing plate 5. A round rod 7 is movably sleeved inside the fixing block 6. A connecting block 8 and a rectangular block 9 are fixedly connected to the left and right sides of the round rod 7, respectively. A spring 10 is fixedly connected to the right side of the connecting block 8. The other end of the spring 10 is fixedly connected to the left side of the fixing block 6. A connecting rod 11 is hinged to the right side of the rectangular block 9. A pin 12 is hinged to the other end of the connecting rod 11. There are two pins 12. The inner sides of both pins 12 are movably connected to the outer surface of the connecting pipe 3, and the outer surfaces of both pins 12 are movably connected to the inner surface of the material tank 4.

[0024] By pressing the connecting block 8, the connecting block 8 will compress the spring 10 and drive the round rod 7 to move to the right, which in turn will cause the rectangular block 9 to move to the right and drive the two connecting rods 11 to rotate, thereby causing the two pins 12 to move in opposite directions and separate from the material tank 4, thus achieving the purpose of quickly installing and disassembling the material tank 4.

[0025] The bottom of the fixed plate 5 is provided with a limiting groove 13, and the inside of the limiting groove 13 is movably connected to a limiting block 14. There are two limiting blocks 14, and the bottom of the two limiting blocks 14 are respectively fixedly connected to the top of the two pins 12.

[0026] The design of the limiting groove 13 and the limiting block 14 serves to limit the position of the pin 12.

[0027] The spray gun 1 has a flow regulating valve 15 fixedly installed on its right side. The flow regulating valve 15 is circular in appearance.

[0028] The flow regulating valve 15 is designed to regulate the rate at which the nozzle 2 sprays pigment.

[0029] The bottom of the spray gun 1 is fixedly equipped with an air pressure regulating valve 16, and the bottom of the spray gun 1 is fixedly connected to an air inlet 17 located to the right of the air pressure regulating valve 16.

[0030] The design of the air pressure regulating valve 16 is to control the air pressure inside the air inlet 17.

[0031] The spray gun 1 has a trigger switch 18 hinged to its front side, and the outer surface of the trigger switch 18 is smooth.

[0032] The trigger switch 18 is designed to control the material spraying from the nozzle 2.

[0033] The spray gun 1 is fixedly connected to a drive motor 19 located below the flow regulating valve 15 on the right side. The other end of the output shaft of the drive motor 19 is fixedly sleeved with a rotating shaft 20. A rotating plate 21 is fixedly sleeved on the outer surface of the rotating shaft 20. A rotating rod 22 is hinged to the left side of the rotating plate 21. An L-shaped block 23 is hinged to the other end of the rotating rod 22.

[0034] When the drive motor 19 is running, the rotating shaft 20 will drive the rotating plate 21 to rotate, which in turn will cause the two rotating rods 22 to drive the two L-shaped blocks 23 to move towards each other, thereby achieving the purpose of locking and fixing the trigger switch 18.

[0035] Among them, the spray gun 1 has a limit rod 24 fixedly installed on both the front and back, and the outer surface of the limit rod 24 is movably connected to the inner surface of the L-shaped block 23.

[0036] The design of the limit rod 24 serves to limit the L-shaped block 23, ensuring that the L-shaped block 23 can move horizontally stably.

[0037] Working principle and usage process of this utility model:

[0038] When replacing the material tank 4, pressing the connecting block 8 will cause the connecting block 8 to compress the spring 10 and drive the round rod 7 to move to the right, which in turn causes the rectangular block 9 to move to the right and drive the two connecting rods 11 to rotate. This causes the two pins 12 to move in opposite directions and separate from the material tank 4. At this time, pulling the material tank 4 downwards can achieve the purpose of quickly disassembling the material tank 4. Then, the new material tank 4 is connected to the connecting tube 3. After that, the connecting block 8 is released. Due to the elasticity of the spring 10, the two pins 12 are reset and inserted into the inside of the material tank 4 and fixed to it.

[0039] To reduce the workload of operators, first press the trigger switch 18 to make the nozzle 2 work normally, then start the drive motor 19, which will cause the rotating shaft 20 to drive the rotating plate 21 to rotate, and then cause the two rotating rods 22 to drive the two L-shaped blocks 23 to move towards each other, thereby achieving the purpose of locking and fixing the trigger switch 18.
