A method for using a convenient safety guardrail for construction, characterized in that: The method comprises the following steps: S1: The upper guardrail (8), the middle guardrail (9), and the lower guardrail (10) are respectively installed in the safety column 1 (1) and the safety column 2 (2), and bolts are passed through the fixing holes (14) through the through-holes on each guardrail to correspond to and butt against each other, thereby fixing and forming a complete safety guardrail; S2: The second connecting plate (3) is clamped on the upper and lower sides of the first connecting plate (4) and is movably plugged in. The second connecting plate (3) and the first connecting plate (4) are rotatably mounted via a shaft (5), and the first safety column (1) and the second safety column (2) are rotatably connected via the shaft (5), so that the angle of the safety guardrail mechanism can be adjusted arbitrarily, facilitating the flexible use of the safety guardrail; S3: Universal wheels (7) are respectively installed at the four top corners of the bottom of the fixed plate (6); S4: During the installation process, the upper guardrail (8), the middle guardrail (9), and the lower guardrail (10) in the safety column 1 (1) and the safety column 2 (2) are turned over and connected and fixed to form a complete safety guardrail. S5: During the disassembly process, the flipped upper guardrail (8), middle guardrail (9), and lower guardrail (10) are retracted into the grooves of the first safety column (1) and the second safety column (2).
