[0028] The opening size of the slot 83 corresponds to the size of the insertion block 81 , the depth of the slot 83 is greater than the length of the insertion block 81 , and the insertion block 81 can be inserted into the slot 83 .

[0029] The opening size of the groove 85 is equal to the opening size of the slot 82 . In the initial state, two-thirds of the arc block 87 is located outside the groove 85 , and the arc block 87 can enter the slot 82 .

[0030] The arc surface of the arc block 87 faces leftward, and the depth of the groove 85 is greater than the length of the arc block 87 . When the arc surface of the arc block 87 is squeezed, it will move into the groove 85 , and the arc block 87 can be completely retracted into the groove 85 .

[0031] The buffer mechanism 9 includes a slot body 91, a fixed plate 4 on one side away from the support column B3, a slide rod 92 is slidably connected inside the slot body 91, a contact plate 93 is fixedly connected to one end of the slide rod 92 away from the slot body 91, and a buffer spring 94 is sleeved on the surface of the slide rod 92.

[0032] In the initial state, both ends of the buffer spring 94 respectively contact the contact plate 93 and the side close to the fixing plate 4 , and the buffer spring 94 is pressed when the contact plate 93 moves to the right.

[0033] The contact plate 93 is square in shape as a whole, and is made of elastic rubber material. The rubber contact plate 93 has a certain elasticity and can provide a certain degree of protection when it is hit.

[0034] A specific application of this embodiment is: when the first guardrail 2 and the second guardrail 5 need to be merged, the second guardrail 5 is pushed to move to the left and overlap with the first guardrail 2. At this time, the insertion block 81 will enter the slot 83 and contact the compression spring 84 to gradually tighten it. At the beginning, the arc surface of the arc block 87 is squeezed by the front end of the insertion block 81 and shrinks into the groove 85. The telescopic spring 86 is gradually tightened. When the groove 85 fits with the top slot 82 of the insertion block 81, the telescopic spring 86 will rebound and drive the arc block 87 to be stuck in the slot 82. At this time, the insertion block 81 cannot be separated from the slot 83, so that the second guardrail 5 and the first guardrail 2 cannot be separated, preventing shaking and re-expansion during transportation. When the second guardrail 5 is opened and the second guardrail 5 and the first guardrail 2 need to be unfolded for use, the pull rod 88 is pulled to drive the arc block 87 to move upward and leave the slot 82. At this time, the compression spring 84 will rebound and drive the insertion block 81 to move so that the groove 85 and the slot 82 are misaligned. At this time, the insertion block 81 can be separated from the slot 83 to unfold the second guardrail 5 and the first guardrail 2. When the second guardrail 5 is pushed to move to the left and overlap with the first guardrail 2, the contact plate 93 will contact the first guardrail 2 and move to the right. At this time, the elasticity of the contact plate 93 itself and the buffer spring 94 will buffer the impact force to prevent the second guardrail 5 from sliding to the left with excessive force, causing the fixed plate 4 to collide with the first guardrail 2 and cause damage.
