[0014] 1. In the utility model, when the equipment is in use, the user places the equipment in a place that needs to be isolated, connects and places the equipment one by one, and isolates the construction site and the pedestrian passage. When the equipment is in use, the user pulls the handle, and the handle moves, driving the card block and the pull rod to move together. Then, when the card block moves, it disengages from the inside of the card slot, and when the pull rod moves, it drives the slider to slide and connect inside the pull hole. When the pull rod moves, it drives the first spring to displace and deform to generate elastic force, and then the guardrail loses its restraint. By setting a connecting device, the guardrail is effectively connected, which plays a role in quickly limiting and fixing the guardrail, reducing the situation when the equipment is in use. Generally, when the equipment is placed, the equipment is directly placed side by side, and the equipment is easily affected by the outside world and shakes, causing the equipment to be placed offset, making it difficult to isolate the construction site.

[0015] 2. In the utility model, by setting an adjusting device, when the equipment is in use, the user pulls the sliding rod, and the sliding rod moves, which drives the adjusting rod to move, and then the adjusting rod moves out of the adjusting groove. When the sliding rod moves, it drives the second spring to displace and deform to generate elastic force, and then the support rod loses its restraint, and the support rod is pulled to slide and adjust inside the rotating column. By setting the adjusting device, the support rod is effectively adjusted, which plays a role in supporting and adjusting the support rod of the rotating column of the equipment, reducing the situation that when the equipment is blocked by soil, the equipment is easily moved due to the large amount of soil, making it difficult to limit the equipment. However, the rotating column is short and it is difficult to support the equipment in different places, thereby improving the practicability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific settings and functions of the connecting device 3 and the adjusting device 4 are described in detail below.

[0024] In this embodiment: the connecting device 3 is arranged on the surface of the guardrail 2, and the connecting device 3 includes a pull groove 31 and a clamping groove 32. The clamping groove 32 is opened on the surface of the guardrail 2, and the pull groove 31 is opened on the surface of the guardrail 2. A pull hole 34 is opened inside the pull groove 31, and a pull rod 33 is slidably connected to the inner wall of the pull groove 31.

[0025] Specifically, a slider 35 is fixedly connected to a side surface of the pull rod 33 , and a first spring 36 is fixedly connected to one end of the pull rod 33 .

[0026] In this embodiment, by providing a slider 35, the pull rod 33 can be limited in movement, thereby reducing the tendency of the pull rod 33 to shake when the device is in use, which makes it difficult for the pull rod 33 to move smoothly.

[0027] Specifically, one end of the first spring 36 away from the pull rod 33 is fixedly connected to the inner wall of the pull groove 31 , and one end of the pull rod 33 away from the first spring 36 is fixedly connected to a clamping block 37 . The first spring 36 is provided to facilitate applying a restoring elastic force to the pull rod 33 .

[0028] Specifically, the clamping block 37 is clamped with the inner wall of the clamping slot 32 , and a pull handle 38 is fixedly connected to the surface of the clamping block 37 . The pull handle 38 is provided to facilitate the movement of the pull rod 33 .

[0029] In this embodiment: an adjusting device 4 is provided on the surface of the railing 2, and the adjusting device 4 includes a limit block 41 and a rotating column 42. The limit block 41 is fixedly connected to the surface of the railing 2, and the rotating column 42 is rotatably connected to the inside of the limit block 41. A support rod 43 is slidably connected to the inner wall of the rotating column 42, and a sliding groove 44 is provided on the surface of the support rod 43. An adjusting groove 45 is provided on the surface of the rotating column 42, and a sliding rod 46 is slidably connected to the inside of the sliding groove 44.

[0030] In this embodiment: by providing a rotating column 42, the guardrail 2 can be supported, thereby reducing the possibility that the guardrail 2 is easily tilted by external forces when the equipment is in use.

[0031] Specifically, one end of the slide rod 46 is fixedly connected to the second spring 48 , and one end of the second spring 48 away from the slide rod 46 is fixedly connected to the inner wall of the slide groove 44 . The second spring 48 is provided to facilitate applying a restoring elastic force to the slide rod 46 .

[0032] Specifically, one end of the slide rod 46 is fixedly connected with an adjusting rod 47 , and the adjusting rod 47 is engaged with the inside of the adjusting slot 45 . The adjusting rod 47 is provided to facilitate the connection and limiting of the support rod 43 and the rotating column 42 .

[0033] Working principle: When the equipment is in use, the user places the equipment in a place that needs to be isolated, connects and places the equipment one by one, and isolates the construction site from the pedestrian passage. When the equipment is in use, the user pulls the handle 38, and the handle 38 moves, driving the block 37 and the pull rod 33 to move together. Then, when the block 37 moves, it disengages from the inside of the slot 32, and when the pull rod 33 moves, it drives the slider 35 to slide and connect inside the pull hole 34. When the pull rod 33 moves, it drives the first spring 36 to displace and deform to generate elastic force, and then the guardrail 2 loses its restraint. By setting the connecting device 3, the guardrail 2 is effectively connected, which plays a role in quickly limiting and fixing the guardrail 2, reducing the situation when the equipment is in use. Generally, when the equipment is placed, the equipment is directly placed side by side, and the equipment is easily affected by the outside world and shakes, causing the equipment to be placed offset, making it difficult to isolate the construction site.

[0034] When the device is in use, the user pulls the slide bar 46, and the movement of the slide bar 46 drives the adjustment rod 47 to move, and the adjustment rod 47 moves out of the adjustment slot 45. When the slide bar 46 moves, it drives the second spring 48 to displace and deform to generate elastic force, and then the support rod 43 loses its restraint, and the support rod 43 is pulled to slide and adjust inside the rotating column 42. By setting the adjustment device 4, the support rod 43 is effectively adjusted, which plays a role in supporting and adjusting the rotating column 42 of the device support rod 43, reducing the device from being blocked by soil due to the large amount of soil, making it difficult to limit the device. However, the rotating column 42 is short and it is difficult to support the device in different places, thereby improving the practicability of the device.
