[0024] The front ends of the two arms of the movable frame 5 are both provided with an inner frame 14 and an outer frame 15. It should be particularly noted that the inner frame 14 and the outer frame 15 are two frames of the same length cut from the entire section of the profile. In other words, the structures of the inner frame 14 and the outer frame 15 are consistent.

[0025] The inner frame 14 and the outer frame 15 on the same arm are kept rotating coaxially through the connecting shaft 13. The inner frames 14 on the two arms are arranged opposite to each other, and the door and window workpiece 17 to be painted is placed between the two inner frames 14. The upper and lower halves of the inner frame 14 are respectively provided with a plurality of pin holes 19 arranged in sequence. When the door and window workpiece 17 is placed in the inner frames 14 on both sides, the stop pins 18 are inserted into the pin holes 19 to limit and fix the door and window workpiece 17. At this time, the paint gun 4 is facing the door and window workpiece 17.

[0026] The lifting and lowering of the movable frame 5 can be controlled by pushing the hydraulic rod 7. In actual application, when the worker places the door and window workpiece 17 at the front end of the movable frame 5 and faces the paint gun 4, the height of the movable frame 5 can be adjusted to ensure that the door and window workpiece 17 can be sprayed with the paint gun 4.

[0027] Fixed blocks 8 are arranged on both sides of the rear end of the movable frame 5, and a double-axis motor 9 is arranged in the middle of the rear end of the movable frame 5.
