As shown in fig. 3 and 4, the metal fastener 4 is a rectangular cross-section fastener with a downward notch, and two opposite side plates 41 of the metal fastener are provided with opposite fastener mounting holes 42. Because the metal roof plate is usually an aluminum alloy plate, the metal fastener of the invention usually adopts the aluminum alloy fastener which is made of the same material as the metal roof plate, so as to avoid electrochemical corrosion, ensure the anticorrosion effect of the roof and well fix the speed reducing plate on the roof plate. The speed reduction plate 1 is shown in fig. 5, 6 and 7 and comprises a metal hole plate 11 which is provided with densely-distributed leak holes 12, the leak holes are transversely waist-shaped holes and are uniformly distributed, and the leak holes in adjacent rows are staggered, so that the rainwater can be blocked and buffered, and can rapidly pass through. The two ends of the metal pore plate are respectively provided with a bent right-angle corner plate 13, and the right-angle corner plate is provided with a speed reducing plate mounting hole 14. The right-angle corner plates 13 at both ends may be bent in opposite directions or in the same direction as shown in fig. 8. And a connecting screw rod 2 is adopted to penetrate through the fastener mounting hole and the speed reducing plate mounting hole, so that the metal fastener and the speed reducing plate are connected. The connection mode of the connecting screw is that two side plates of one metal fastener are respectively connected with a right-angle corner plate of the connected speed reducing plate by the connecting screw 2, and the connection is simple and convenient.
