The self-adjustable safety guardrail includes a support, a crossbar and a vertical pole. The support is fixedly connected to the lower end of the vertical pole. The vertical pole is a telescopic rod structure. The upper end of the vertical pole passes through the first through hole on the crossbar and is fixed by a nut; the crossbars are connected by a diamond-shaped connecting piece, which includes a connecting rod, and connecting plates are respectively fixed at both ends of the connecting rod. The connecting plates of the two connecting rods are fixed by bolts; a cross through hole is provided on the crossbar, and the connecting plates of the two connecting rods are overlapped and installed in the cross through hole and connected by bolts; the two ends of the crossbar are respectively mounted on the vertical pole and fixed by nuts.
