[0041] The locking mechanism 4 can lock and unlock the movable cover 3 at the second position. Any structure in the prior art that can lock and unlock the movable cover 3 at a certain position can be used as the locking mechanism 4 in this embodiment.

[0042] See also Figure 1 At this time, the movable sleeve 3 is in the first position, the locking mechanism 4 is in the unlocked state, and the end of the movable sleeve 3 is just flush with the tip of the vertical rod 2. Figure 1 In the orientation sequence, the movable sleeve 3 can also be in a lower position when it is in the first position, so as to better cover the tip of the vertical rod 2;

[0043] See also Figure 2 At this time, the movable sleeve 3 is in the second position, the locking mechanism 4 is in the locked state, and the tip of the vertical rod 2 extends from the movable sleeve 3. Figure 2 In the orientation sequence, the movable sleeve 3 can also be in a higher position when it is in the second position, so that the tip of the vertical rod 2 can extend further;

[0044] In this embodiment, when the guardrail is not needed or needs to be moved, the movable cover 3 is slid to the first position so that the movable cover 3 covers the lower end of the vertical rod 2, so that the tip of the vertical rod 2 can be hidden in the movable cover 3 to prevent the tip from causing damage to external objects. When the guardrail needs to be used, after the guardrail is moved to a suitable position, the movable cover 3 is slid to the second position and the movable cover 3 is locked in the second position by the locking mechanism 4. At this time, the tip of the vertical rod 2 extends out of the movable cover 3, and the vertical rod 2 can be inserted into the ground to make the guardrail play a blocking role; when the movable cover 3 is to be slid from the second position to the first position, the locking mechanism 4 is first unlocked, and the movable cover 3 can be slid;

[0045] In this embodiment, a plurality of guardrails may be distributed at intervals to form a desired shape and structure, and adjacent guardrails are independent.

[0046] Example 2

[0055] The thrust spring 403 is arranged in the mounting groove 401, and the two ends of the thrust spring 403 are respectively connected to the side wall of the mounting groove 401 and the second end of the swing block 402. When the movable sleeve 3 is in the first position, the second end of the swing block 402 is squeezed by the inner wall of the movable sleeve 3 and is located in the mounting groove 401. At this time, the thrust spring 403 is squeezed. When the movable sleeve 3 slides to the second position, the elastic force of the thrust spring 403 can push the second end of the swing block 402 outward toward the mounting groove 401, so that the second end of the swing block 402 is against the bottom end of the movable sleeve 3, and the movable sleeve 3 can be locked in the second position; when the movable sleeve 3 needs to be unlocked, the second end of the swing block 402 is pushed inward toward the mounting groove 401.

[0056] In this embodiment, there are multiple groups of swing blocks 402, which are spaced apart along the circumference of the vertical rod 2. Each group of swing blocks 402 corresponds to a group of thrust springs 403.
