[0030] When this utility model is in operation, the cartridge bottle 6 is held in the working position by the clamping arm 44 and the clamping claw 42 under the action of the spring 43.

[0031] This invention can precisely control the spraying time and movement state. Different air atomizing spray guns can be matched to make them concentric with the cartridge bottle 6 by switching the spray gun adapter block 52 and adjusting the movable base plate 41. The parameters of cartridge bottle spraying can be quantified by the parameters set by the industrial computer 13.
