[0031] In this embodiment, the personnel first places the first guardrail net 1 to a suitable position, and then supports the first guardrail net 1 through the supporting feet 113. When it is necessary to splice them, another guardrail net can be picked up and the connecting block 103 of the other guardrail net can be embedded into the interior of the connecting piece 105. Then, the connecting block 103 is pushed, and the pushing block 106 is driven by the connecting block 103 to move to the left inside the connecting piece 105, and at the same time, the first sliding block 107 slides on the inner surface of the first sliding groove 108, and then the first return spring 109 is squeezed by the pushing block 106 to shrink the first return spring 109. When the pushing block 106 slides to the left, the movable column 110 is squeezed by the pushing block 106, so that the movable column 110 slides outward, and then the pulling block 111 is driven to move synchronously by the movable column 110, and then the second return spring 112 is pulled outward by the pulling block 111 to extend it. After the connecting block 103 is embedded to a certain extent, the second return spring 112 is The spring 112 is reset to its original position, and then the movable column 110 is driven to slide inwardly by the pulling block 111, so that the movable column 110 is embedded in the connecting groove 104, thereby connecting the two guardrail nets, and adjusting the angles of the two guardrail nets by the hinge 102 to form a circle, set it outside the foundation pit, and warn passers-by through the warning strip 101. When the guardrail net needs to be disassembled, the pulling block 111 can be pulled outward to make the movable column 110 disengage from the connecting groove 104, and the two guardrail nets are pulled outward to make the connecting block 103 disengage from the connecting piece 105, thereby completing the disassembly of the two guardrail nets.

When the pushing block 106 slides to the left, the movable column 110 will be squeezed by the pushing block 106, so that the movable column 110 slides outward, and then the pulling block 111 is driven to move synchronously through the movable column 110, and then the second return spring 112 is pulled outward by the pulling block 111 to extend it. After the connecting block 103 is embedded to a certain extent, the second The second reset spring 112 is reset, and then the movable column 110 is driven to slide inwardly through the pulling block 111, so that the movable column 110 is embedded in the connecting groove 104, thereby connecting the two guardrail nets, and adjusting the angles of the two guardrail nets through the hinge 102 to form a circle, set it outside the foundation pit, and warn passers-by through the warning strip 101. When the guardrail net needs to be disassembled, the pulling block 111 can be pulled outward to make the movable column 110 disengage from the connecting groove 104, and the two guardrail nets are pulled outward to make the connecting block 103 disengage from the connecting piece 105, thereby completing the disassembly of the two guardrail nets. In addition, through the arrangement of the connecting piece 105 and the movable column 110 and other structures, not only can the firmness of the guardrail net be ensured during connection, the risk of accidental loosening or collapse is reduced, and the safety of the construction site is improved, but also the splicing and disassembly process of the guardrail net can be made relatively simple. Only the corresponding parts need to be pushed or pulled to complete the connection or separation of the guardrail net, saving time and labor costs. When in use, personnel can first pull the pin column 204 upwards to disengage it from the pin hole 203, and pull the first guardrail net 1 outward to make it move on the outer surface of the second guardrail net 2, while driving the second slider 202 to slide on the inner surface of the second slide groove 201, thereby expanding the guardrail net. Through the setting of the second guardrail net 2 and the second slide groove 201 and other structures, the expansion and contraction of the guardrail net can be achieved. This design allows the length of the guardrail net to be adjusted as needed to adapt to foundation pits or construction site boundaries of different lengths, thereby improving the practicability of the device.
