[0007] Furthermore, the fixing mechanism includes two fixing frames respectively arranged on one side of the first guardrail and the second guardrail, and a connecting rod is provided on the side of the first guardrail and the second guardrail away from the fixing frame, an installation groove is opened inside the fixing frame, a plug-in groove is opened on the connecting rod, a plug-in rod is plugged into the fixing frame, the front side of the plug-in rod passes through the fixing frame and extends out of the front side of the fixing frame, a connecting plate is fixedly provided on the front side of the plug-in rod, springs are fixedly provided on both sides of the connecting plate, the rear end of the spring is fixedly connected to the front side of the fixing frame, the plug-in rod is adapted to the plug-in groove, and a pull ring is fixedly provided on the front side of the connecting plate for connecting multiple first guardrails together.

[0008] Furthermore, an extension mechanism for adjusting the distance between the first guardrail and the second guardrail is provided at the top of the first guardrail, and the extension mechanism includes two first extension rods provided on both sides of the second guardrail, first slide grooves are provided on both sides of the inside of the first guardrail, the first extension rods and the first slide grooves are adapted to each other, a plurality of first threaded holes are provided on the two first extension rods, second threaded holes are provided on both sides of the first guardrail, the first threaded holes and the second threaded holes that are connected are threadedly connected with the same bolt, a plurality of second slide grooves are provided on the first guardrail, and a plurality of second extension rods are fixedly provided at the bottom of the second guardrail, the second extension rods are adapted to the second slide grooves, and are used to adjust the distance between the first guardrail and the second guardrail.

[0009] The utility model embodiment has the following advantages:

[0010] 1. Insert the connecting rod on one first guardrail and the second guardrail into the mounting groove on the other first guardrail and the second guardrail, then pull the pull ring to drive the plug-in rod to move, and the connecting plate on one side of the plug-in rod can use its own elasticity to make the plug-in rod tightly inserted into the connecting rod to prevent the plug-in rod from slipping out of the connecting rod.
