At this time, start the drive motor, which drives the half gear to rotate, thereby driving the fixed frame to move back and forth, and in turn driving the spray head below to move back and forth for spraying.

[0047] This invention relates to a coating spraying device that allows for easy adjustment of the spraying range. It can expel air bubbles in the coating through the orifice, reducing air bubble defects in the coating after spraying, improving coating quality, and reducing the risk of damage to the stirring blades. Furthermore, it can expand the spraying coverage without moving the main body of the spraying device, reducing the time required to adjust the device position, thereby improving spraying efficiency.
