The frame 4 is placed on top of the polyethylene board 2, and the fixing bolts 12 are inserted into the holes of the frame 4 and aligned with the threaded cylinders 11. The fixing bolts are then rotated. 12. Connect the fixing bolt 12 and the threaded cylinder 11. Use the stainless steel sheet 3 and the skeleton 4 to clamp the low-temperature resistant polyurethane board 1 and the polyethylene board 2. When it is necessary to splice the two boards, align the fixing rod 6 of the limiting sleeve 5 with the guide sleeve 7, slide the fixing rod 6 into the inside of the guide sleeve 7, and after the fixing rod 6 is aligned with the screw 10, it drives the large bevel gear 8 to rotate.
