The gas pressure inside the storage box 35 will increase, and the glass fiber reinforced plastic resin will break through the restriction of the air pressure valve 38 and enter the connecting pipe 37. The connecting pipe 37 will transport the glass fiber reinforced plastic resin to the spraying The spray is sprayed out from the head 39 for spraying, which is very practical. After being turned on, the linear motor 41 will drive the electric gear rod 42 to move repeatedly. While the electric gear rod 42 moves, it will engage with the gear 44. The gear 44 will rotate to drive the nozzle 39 to rotate repeatedly to achieve the effect of uniform coating. When the electric gear rod 42 drives the extrusion plate 43 to return to its original position, the airbag 32 will not continue to be squeezed.
