During this process, the connecting rod and the turntable rotate synchronously following the movement of the positioning rod, ultimately positioning a convex lens mounted on the side wall of the turntable precisely in front of the light from the lampshade. At this point, the light, refracted by the convex lens, forms a focusing effect, significantly enhancing the illumination brightness of a specific area.
