[0031] like Figure 1-Figure 5The embodiment shown is a method for using a movable guardrail lifting base: the base 1 is placed in a suitable position. The construction worker presses down the swing rod 207 according to the construction site to rotate the connecting block 203. The rotation of the connecting block 203 drives the connecting frame 204 to swing, thereby driving the gear 202 to rotate through the protrusion 205. The rotation of the gear 202 causes the spiral protrusion 206 on the bottom surface of the disk 201 to drive the lifting rod 209 to rise until it reaches the appropriate position. Similarly, when it is necessary to lower the base, the swing rod 207 is moved up to make the gear 202 rotate in the opposite direction, so that the spiral protrusion 206 drives the lifting rod 2 09 descends; after adjusting the placement base 1, install the connecting plate 3 on the lifting rod 209, move the guardrail rod 5 upward, and under the action of the hinge, the column 4 stands up synchronously and reaches the appropriate position. The fixed head 404 is buckled into the fixing hole 407 along the inclined surface of the ladder block 408. Under the action of the spring 405, a stable structure is formed between the guardrail rod 5 and the column 4; when it needs to be put away, press the movable block 401 upward to make it slide upward along the sliding plate 402, so that the spring 405 is deformed under force, the fixed head 404 moves out of the fixing hole 407, and press the guardrail rod 5 downward to make it folded, which is convenient for construction workers to put it away.
