When the rotating shaft rotates, it drives the gear to rotate, and the gear drives the meshing rack to slide. The rack compresses the spring, and at the same time, the rack drives a push rod to push a vertical rod, forcing the vertical rod to drive a horizontal rod to rotate a rotating plate, and when the rotating plate rotates, an arc-shaped linkage groove contacts a sliding rod, forcing the sliding rod to drive the slider to slide along the sliding groove, thereby forcing the slider to drive a clamping block to clamp the outer edge of the photovoltaic panel, so as to prevent the entire device from shaking when the rotating shaft drives the brush to clean, resulting in insufficient cleaning. The symmetrical clamping blocks can make the brush more stable when cleaning the photovoltaic panel.
