[0027] There are two insert blocks 507 and two adjusting plates 508, and the cross-section formed by the two insert blocks 507 and the adjusting plates 508 is in an inverted L shape;

[0028] There are two groups of running wheels 510, each group of running wheels 510 is provided with two, and the two groups of running wheels 510 are symmetrically distributed;

[0029] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, when in use, by screwing the adjusting rod 504, the driven bevel gear 509 is driven to rotate under the action of the active bevel gear 505, thereby driving the driven shaft 506 to rotate synchronously, thereby driving the adjusting block 501 to make a relative horizontal movement, and driving the connecting plate 503 to move downward under the action of the second hinge block 512, the support plate 502 and the first hinge block 511, until the walking wheel 510 is in contact with the ground. Through the above operation, it is convenient for the staff to push the fence body 1, so as to adjust the position of the fence body 1, thereby improving its flexibility;

[0030] A slot 2 is provided on one side of the fence body 1, and a fixing block 4 is fixed inside the slot 2, and a card slot 3 is provided inside the fixing block 4. A connecting slot 8 is provided at the top of the fence body 1, and a warning light 6 is provided inside the connecting slot 8. A limiting mechanism 7 is provided inside the fence body 1 on both sides of the warning light 6.

[0031] The limiting mechanism 7 includes a moving rod 705, and the moving rod 705 is arranged inside the fence body 1, and the outer side of the moving rod 705 is evenly wound with an extrusion spring 703, a stopper 706 is fixed on one side of the moving rod 705, and guide grooves 704 are arranged on both sides of the stopper 706, and the guide grooves 704 are all opened inside the fence body 1, and a limiting block 702 is fixed on one side of the stopper 706, and a limiting groove 701 is arranged on the outer side of the limiting block 702, and the limiting grooves 701 are all opened inside the warning light 6;

[0032] Two extrusion springs 703 are provided, the two extrusion springs 703 are symmetrically distributed, and the two extrusion springs 703 are both in a stretched state;

[0033] The stopper 706 slides inside the guide groove 704, and the limit block 702 is slidably connected to the fence body 1 through the stopper 706 and the guide groove 704;

[0034] A reflective strip 9 is evenly adhered to one side of the front of the fence body 1;

[0035] Specifically, Figure 3 , Figure 4 As shown, when in use, the stopper 706 is driven to move horizontally by resetting the extrusion spring 703 until the limit block 702 is inserted into the limit groove 701, thereby facilitating the limiting of the warning light 6. Through the above operation, the warning light 6 can be easily fixed to the top of the fence body 1, thereby warning pedestrians and preventing pedestrians from mistakenly entering the tunnel construction at night, thereby improving its practicality.

[0036] Working principle: When the utility model is in use, first, the active bevel gear 505 is driven to rotate by positively screwing the adjusting rod 504. Since the active bevel gear 505 and the driven bevel gear 509 are meshed with each other, the active bevel gear 505 rotates and drives the driven bevel gear 509 to rotate synchronously, thereby driving the driven shaft 506 to rotate synchronously, and then drives the two adjusting blocks 501 to make relative horizontal movements. While the adjusting block 501 makes relative horizontal movements, it drives the second hinge block 512 to make relative horizontal movements synchronously. With the cooperation of the support plate 502, the first hinge block 511 is pushed to move downward, thereby driving the connecting plate 503 to make synchronous downward movements. While the connecting plate 503 makes downward movements, it drives the walking wheel 510 to make synchronous downward movements until the walking wheel 510 is in contact with the ground. Through the above operation, it is convenient for the staff to push the fence body 1 to adjust the position of the fence body 1, thereby reducing the labor intensity of the staff and improving its practicality.

[0037] Secondly, when the fence body 1 is pushed to the specified position, the plug block 507 and the adjustment plate 508 on one group of fence bodies 1 are inserted into the slot 2 on the other group of fence bodies 1, and the adjustment rod 504 is screwed in the opposite direction to drive the adjustment plate 508 to move downward, thereby driving the plug block 507 to move downward synchronously, until the plug block 507 is inserted into the slot 3. Through the above operation, it is convenient to splice and install multiple groups of fence bodies 1, thereby improving the convenience of installation. While the adjustment rod 504 rotates, it drives the active bevel gear 505 to rotate synchronously, and drives the driven shaft 506 to rotate synchronously under the action of the driven bevel gear 509, thereby driving the two adjustment blocks 501 to move horizontally in the opposite direction, and drives the connecting plate 503 to move upward under the cooperation of the second hinge block 512, the support plate 502 and the first hinge block 511, so as to facilitate the collection of the walking wheel 510 into the fence body 1. Through the above operation, the stability of the installation of the fence body 1 is improved to prevent it from sliding or even tipping over.

[0038] Finally, by inserting the warning light 6 into the connecting groove 8, the moving rod 705 is pulled during the insertion process to drive the block 706 to move horizontally, so that the block 706 slides inside the guide groove 704. The guide groove 704 can limit and guide the moving block 706, so that the movement of the block 706 is more stable. While the block 706 moves horizontally, it squeezes the squeezing spring 703, so that the squeezing spring 703 is compressed by the squeezing force. While the block 706 moves horizontally, it drives the limit block 702 to make synchronous horizontal movement. The limit block 702 is retracted into the interior of the fence body 1 until the warning light 6 and the connecting groove 8 are fitted with each other, and then the moving rod 705 is loosened so that the squeezing force of the squeezing spring 703 disappears, thereby pushing the stop block 706 to move horizontally. While the stop block 706 moves horizontally, it drives the limit block 702 to move horizontally synchronously until the limit block 702 is inserted into the interior of the limit groove 701. Through the above operation, the warning light 6 can be easily fixed to the top of the fence body 1, so as to play a warning role at night, prevent outsiders from mistakenly entering the tunnel construction site at night, and then reduce the probability of safety hazards.
