When the strip board is to be half-expanded, first unscrew the fourth hand-tightening bolt 20, and then unfold the second strip board 3, and then the screw of the second hand-tightening bolt 14 is passed through the round through hole on the second positioning plate 13 and connected with the screw hole at the bottom of the second strip board 3, and finally the first valve 9 is opened and closed. Close the second valve 10, and then start the machine. Paint can be sprayed from the nozzles on the first spray pipe 6 and the second spray pipe 7, further expanding the spraying range of the paint. When the strip board is to be fully unfolded, the third hand-tightening bolt 17 is first unscrewed on the basis of the semi-expanded strip board, and then the third strip board 4 is unfolded, and then the screw of the second hand-tightening bolt 14 is passed through the round through hole on the second positioning plate 13 and connected with the screw hole at the bottom of the second strip board 3. Finally, open the second valve 10, and then start the machine. Paint can be sprayed from the nozzles on the first spray pipe 6, the second spray pipe 7 and the third spray pipe 8, further expanding the spraying range of the paint. The strip boards on the left and right sides of the sprayer can be folded, semi-expanded or fully unfolded separately, which can adapt to a variety of different working environments such as narrow aisles, rooms, open areas, etc.
