The pulling block 114 can be limited by the first card box 115 and the second card box 116 to prevent the pulling block 114 from loosening. The elastic card block 119 can facilitate the connection between the first card box 115 and the second card box 116.

[0030] When using the utility model to connect two groups of guardrails, the fixing rod 108 is continuously pulled to move the fixing rod 108 out of the connecting seat 110, and then the connecting rod 113 is placed in the square groove 112. At this time, the fixing rod 108 is relaxed, and the fixing rod 108 is automatically engaged in the connecting rod 113 under the action of the spring 107. Then, according to the above operation, another group of guardrails can be connected to the connecting rod 113. In this way, the technical problem that the two groups of telescopic railings 101 are connected by bolts, and the fixing of the bolts requires the use of special tools, and the disassembly and assembly process of the bolts is very time-consuming and labor-intensive, making it inconvenient to quickly assemble or separate the two groups of telescopic railings 101 is solved.
