Then, rotate the bolt 4 by thread, and the bearing 21 prevents the pressure plate 5 from rotating, thereby pushing the pressure plate 5 down to adjust the degree of pressure according to the thickness of the mounting frame 14. This can effectively fix photovoltaic panel bodies 15 of different thicknesses. Second, the rubber pad 7 can improve the waterproofness and tightness of the clamping point. Then, insert the clamping rod 8 into the groove of another set of rubber pads 7 to realize the combined installation and fixation of multiple sets of photovoltaic panel bodies 15. Finally, rotate the first fastening nut 13 by thread to push the movable plate 12 down. Combined with the fixing plate 10, the connection of the two sets of spring plates 6 can be clamped and fixed, thereby improving the stability of the connection.
