When the limit rod 332 is inserted into the limit hole 326, the rotating part 32 cannot rotate. When the limit rod 332 is pulled out of the limit hole 326, the rotating part 32 can rotate.

[0041] When it is necessary to replace the vertical rod portion 1 or the cross rod portion 2, unscrew the screws on the rod seat 12 to make it separate from the ground, and at the same time pull the pull rod 331 at the same end of the upper cross rod 21 and the lower cross rod 22 upward, the pull rod 331 drives the limiting rod 332 and the retaining ring 333 to move upward, the spring 334 is compressed, the limiting rod 332 leaves the limiting hole 326, hold the knob 321 and rotate it 90° counterclockwise, the first limiting block 323 follows the knob 321 to rotate 90° through the connecting rod 322, the first limiting block 323 rotates to the vertical position, parallel to the side hole 14, pull the vertical rod portion 1 outward, pull the first limiting block 323 out of the side hole 14, the vertical rod portion 1 is separated from one end of the cross rod portion 2, and the cross rod portion 2 is pulled outward in the same way to remove the cross rod portion 2 from the vertical rod portion 1 at the other end. A limit block 323 is inserted into the corresponding side hole 14, and the knob 321 is held and rotated 90° clockwise. The first limit block 323 is perpendicular to the side hole 14. At this time, the first limit block 323 abuts against the wall of the hollow cavity inside the vertical pole 11 and is limited by the wall of the hollow cavity to prevent it from escaping from the side hole 14. At this time, the limit hole 326 is facing upward, and the pull rod 331 is released. The spring 334 rebounds and pushes the pull rod 331 downward through the retaining ring 333 to insert it into the limit hole 326, preventing the rotating part 32 from rotating in the vertical pole 11 and the base part 31, causing the first limit block 323 to escape from the side hole 14. According to the same method, the two ends of the cross bar part 2 are connected to the corresponding vertical pole part 1, and then the rod seat 12 is fixed to the ground with screws. Through the above arrangement, the guardrail can be easily installed, disassembled, replaced and maintained.
