[0026] As a technical optimization scheme of the utility model, by setting a retraction mechanism 6, the telescopic rod 5 can be connected and installed through the fixing block 61 and the connecting block 62. When the telescopic rod 5 brings the embedded part 3 out of the soil, the operator pushes the telescopic rod 5 to make the telescopic rod 5 move in a circle through the fixing block 61 and the connecting block 62, so that the telescopic rod 5 fits with the bottom of the force-bearing plate 4, and then the operator flips the force-bearing plate 4 through the hinge, so that the force-bearing plate 4 drives the telescopic rod 5, the fixing block 61 and the connecting block 62 to be retracted into the retraction groove 63, so as to avoid the telescopic rod 5, the fixing block 61 and the connecting block 62 being exposed to the outside and damaged, while ensuring the overall aesthetics.

[0027] refer to Figure 1 and Figure 3 A reinforcing plate 7 is inserted into the top of the load-bearing plate 4, and the other end of the reinforcing plate 7 is inserted and fixed to the pillar 2. The top and bottom of the reinforcing plate 7 are fixedly connected with a quick installation component 71.

[0028] As a technical optimization scheme of the utility model, by setting a reinforcement plate 7, when the telescopic rod 5 needs to be used after the load-bearing plate 4 is unfolded, the reinforcement plate 7 is plugged and installed with the load-bearing plate 4 and the pillar 2 through the quick installation component 71, so that the reinforcement plate 7 limits the load-bearing plate 4 to avoid the load-bearing plate 4 flipping when the telescopic rod 5 is lifted, and then the load-bearing plate 4 can provide a stable load-bearing point for the telescopic rod 5 through the reinforcement plate 7. At the same time, the reinforcement plate 7 can ensure the strength of the load-bearing plate 4 and avoid deformation of the load-bearing plate 4.

[0029] refer to Figure 3 The quick installation component 71 includes an insert block 711, which is fixedly connected to the top and bottom of the reinforcement plate 7. The top of the reinforcement plate 7 and the front and back sides of the pillar 2 are provided with slots 712 for use with the insert block 711.

[0030] As a technical optimization scheme of the utility model, by setting a quick installation component 71, when the force-bearing plate 4 is unfolded, the operator picks up the reinforcement plate 7 to drive the plug block 711 to move to the position of the slot 712, and then aligns the plug block 711 with the slot 712. Then, the operator pushes the reinforcement plate 7 to make the reinforcement plate 7 drive the plug block 711 to slide into the slot 712, thereby completing the installation of the reinforcement plate 7 and ensuring the convenience of installation by the operator.

[0031] refer to Figure 2 The output end of the telescopic rod 5 is fixedly connected with an expansion plate 8, and the expansion plate 8 is used in conjunction with the telescopic rod 5.

[0032] As a technical optimization solution of the utility model, by providing the expansion plate 8, when the output end of the telescopic rod 5 contacts the ground, the expansion plate 8 can increase the contact area between the output end and the ground, thereby preventing the output end from being stuck in the soil.

[0033] refer to Figure 3 The outer side of the connecting block 62 is fixedly connected to a limiting plate 9 , and the limiting plate 9 is used in conjunction with the fixing block 61 .

[0034] As a technical optimization solution of the utility model, a limit plate 9 is provided so that the limit plate 9 and the connecting block 62 are fixedly installed. When the telescopic rod 5 is flipped through the fixing block 61 and the connecting block 62, the limit plate 9 limits the fixing block 61 to prevent the fixing block 61 from flipping too far and causing the telescopic rod 5 to slip.

[0035] refer to Figure 1 A handle 10 is fixedly connected to the outer side of the top of the force-bearing plate 4.

[0036] As a technical optimization solution of the utility model, a handle is provided so that the handle is fixedly installed on the force-bearing plate 4, so that the handle 10 can increase the contact area between the operator's hand and the force-bearing plate 4, ensuring the convenience of the operator pulling the force-bearing plate 4.

[0037] The working principle and use process of the utility model are as follows: when in use, the operator first digs an installation pit on the ground, puts the embedded part 3 into the installation pit, and then fills the soil back into the installation pit, thereby ensuring the stability of the guardrail body 1. When the operator needs to remove the guardrail body 1 from the soil, the operator pulls the handle 10 to drive the force plate 4 to flip through the hinge, and then the operator picks up the reinforcement plate 7 to drive the plug 711 to move to the slot 712 position, and then the plug 71 1 is aligned with the slot 712, and then the operator pushes the reinforcing plate 7, so that the reinforcing plate 7 drives the insert block 711 to slide into the slot 712, thereby completing the installation of the reinforcing plate 7, and the reinforcing plate 7 limits the load-bearing plate 4, so that the angle between the load-bearing plate 4 and the support 2 is close to ninety degrees, and then the operator pulls the telescopic rod 5 downward, so that the telescopic rod 5 drives the fixing block 61 to flip downward through the connecting block 62. During the flipping process, the limiting plate 9 limits the fixing block 61 to prevent the fixing block 61 from flipping too far, so that The telescopic rod 5 is turned over by the limit plate 9 to form an angle of nearly ninety degrees with the force-bearing plate 4. At this time, the operator starts the telescopic rod 5, and then the output end of the telescopic rod 5 drives the expansion plate 8 to move toward the ground and contact it. The output end is continuously moved downward, so that the force-bearing plate 4 generates an upward force through the telescopic rod 5, and then the force-bearing plate 4 can drive the pillar 2 to move upward, so that the pillar 2 drives the embedded part 3 out of the soil, thereby completing the removal of the embedded part 3, which improves the convenience of the operator to take out the embedded part 3. When the removal is completed, The operator disassembles the reinforcement plate 7 and places it inside the retraction groove 63, and then pushes the telescopic rod 5, so that the telescopic rod 5 moves in a circle through the fixing block 61 and the connecting block 62, so that the telescopic rod 5 fits with the bottom of the force-bearing plate 4, and then the operator flips the force-bearing plate 4 through the hinge, so that the force-bearing plate 4 drives the telescopic rod 5, the fixing block 61 and the connecting block 62 to be retracted into the retraction groove 63, so as to prevent the reinforcement plate 7, the telescopic rod 5, the fixing block 61 and the connecting block 62 from being exposed to the outside and being damaged, while ensuring the overall aesthetics.

[0038] When the operator needs to retract the embedded groove, the stress plate 4 drives the telescopic rod 5 to unfold, and then the operator pulls the telescopic rod 5 to flip downward through the retracting mechanism 6, and the operator starts the telescopic rod 5, and then the output end of the telescopic rod 5 moves toward and contacts the ground, and the output end is continuously downward, so that the stress plate 4 generates an upward force through the telescopic rod 5, and then the stress plate 4 can drive the pillar 2 to move upward, so that the pillar 2 drives the embedded part 3 out of the soil, thereby completing the disassembly of the embedded part 3, improving the convenience of the operator to remove the embedded part 3, and solving the problem that in order to ensure the stability of the installation, the embedded part needs to be buried in the soil to ensure the stability of the installation. However, when the operator needs to disassemble the guardrail, in order to avoid damage to the guardrail, the operator is also required to dig the soil before the embedded part can be taken out. This disassembly method is too troublesome and reduces the work efficiency.
