[0013] Beneficial effects: 1. The column gear II meshes with the toothed rod I, the column gear II rotates by 90 degrees, the column gear II rotates to drive the support rod to rotate, the torsion spring is twisted, the support rod rotates to drive the photovoltaic frame to rotate by 90 degrees, so that the groove of the photovoltaic frame is directly opposite the bottom of the painting workshop, and the groove of the photovoltaic frame moves to the top of the small rotary disc nozzle. The user controls the small rotary disc nozzle to start spraying, and the small rotary disc nozzle reciprocatingly extends into and out of the groove of the photovoltaic frame during the spraying process, thereby spraying the side wall of the groove of the photovoltaic frame.

In this way, the large rotary disc nozzle can more uniformly spray around the photovoltaic frame, thereby further improving the spraying quality of the photovoltaic frame.
[0015] 3. Limiting rails one and two will gradually squeeze the top rod. Under the pressure, the top rod will move closer to the photovoltaic frame. The pressure spring two will be compressed. The movement of the top rod will drive the squeezing rod to move together, so that the squeezing rod will extend into the support rod. After the center of the first arc area of the squeezing rod coincides with the rotation axis of the support rod, the squeezing force of limiting rails one and two on the top rod will no longer increase. During the process of the squeezing rod extending into the support rod, the conical protrusion on the squeezing rod will squeeze the clamping rod, so that the clamping rod will extend out of the support rod. The pressure spring three will be compressed, and the rubber pad on the clamping rod will contact the photovoltaic frame, thereby further fixing the photovoltaic frame. In this way, the stability of the photovoltaic frame during the moving coating process is improved, thereby improving the coating quality of the photovoltaic frame. Attached Figure Description
