When the railing 1 is rotated, the U-shaped column 41 at the other end is rotated on the outside of the long rod 42, so that the angle between the two groups of railings 1 can be adjusted, so that the direction of the guardrail body can be adjusted. A fixed block 43 is fixedly installed on the outside of the top of the long rod 42, and a passive rod 45 is hingedly installed inside the fixed block 43. A slider 44 is slidably installed on the outside of the bottom end of the long rod 42, so that the slider 44 is moved in the direction of the fixed block 43 on the outside of the long rod 42. Sliding, so that the overall length of the guardrail body becomes longer, so as to achieve the effect of adjusting the size of the guardrail, the slider 44 is hingedly installed with an active rod 46, and the active rod 46 is rotatably installed with a clamping column 47. When in use, when the railing 1 on one side is pulled, the passive rod 45 and the active rod 46 are gradually expanded from the initial contracted state by cooperating with the clamping column 47. The clamping column 47 is rotatably installed inside the passive rod 45. When the railing 1 is pushed in the direction, the passive rod 45 and the active rod 46 are gradually contracted, so as to facilitate storage. Further, the thickness of the short column 2 and the long column 3 are adapted, and the cross-sectional area of the long column 3 is larger than the cross-sectional area of the short column 2. Further, the railing 1, the U-shaped column 41, the long rod 42, the fixed block 43 and the slider 44 are provided in two groups, and the passive rod 45, the active rod 46 and the clamping column 47 between the two groups of railings 1 are provided in multiple groups, and the multiple groups of passive rods 45, active rods 46 and clamping columns 47 are linearly arrayed.

[0031] Working principle: When in use, when the railing 1 on one side is pulled, the passive rod 45 and the active rod 46 are gradually expanded from the initial contracted state by cooperating with the clamping column 47, so that the slider 44 slides outside the long rod 42 toward the fixed block 43, so that the overall length of the guardrail body becomes longer, so as to achieve the effect of adjusting the size of the guardrail. On the contrary, when the railing 1 is pushed in the direction, the passive rod 45 and the active rod 46 are gradually contracted, so as to facilitate storage. Further, when the railing 1 is rotated, the U at the other end is The profile column 41 rotates on the outside of the long rod 42, so that the angle between the two groups of railings 1 can be adjusted, thereby adjusting the direction of the guardrail body. Wheels 59 are installed at the bottom of the guardrail, which can be easily operated when moving. When working at a fixed location, the pull rod 57 can be lifted from the groove 58, and the rebound tension of the spring 55 drives the pin 54 to pass through the boss 53 and insert into the round hole 52 provided on the special-shaped block 51, so that the guardrail body is placed more stably. If it needs to be moved, the pull rod 57 can be lifted and fixed on the groove 58 of the short column 2.
