[0024] When working, by connecting the equipment and the robotic arm, air pressure will enter the interior of the spray gun rod 1 through the first sealing port 5, pushing the piston 906 and pulling the movable needle 7, so that the air pressure is mixed with the spray paint entering from the second sealing port 6 to push the paint to be sprayed out. The spray gun rod 1 and the nozzle connection end 3 are both made of high-temperature resistant materials, which serve to protect the equipment. When spraying, we can push the limiting sliding block 904 under the rotation of the threaded screw 901 by twisting the adjusting cap button 902 to control the distance between the limiting sliding block 904 and the piston 906, and the volume of the hole air pressure entering. When we adjust to the appropriate size, we fix it by twisting the fixing nut 903. When we need to adjust the angle, we twist the first nut 802 so that the rotating adjustment ball 804 can move inside the threaded connection sleeve 801. When the rotating adjustment ball 804 interacts to the appropriate position, the angle is fixed by twisting the first nut 802 under the contact between the rubber limiting ring 803 and the rotating adjustment ball 804, and then spraying is performed.
