[0025] The lifting mechanism 2 includes an adjusting rail 21, a sliding plate 22, a toothed groove 23, a rotating shaft 24, a turntable 25, a gear 26, a limiting hole 27, and a limiting rod 28. The adjusting rail 21 is fixedly connected to both sides of the top of the support plate 1. The sliding plate 22 is slidably connected inside the adjusting rail 21. A toothed groove 23 is provided on one side of the sliding plate 22. A rotating shaft 24 is provided at the top of the adjusting rail 21. The middle part of the gear 26 is fixedly connected to the middle part of the rotating shaft 24. The outer wall of the gear 26 is meshed with the toothed groove 23. The outer wall is constructed by sliding the limiting rod 28 through the limiting hole 27 between the turntable 25 and the adjusting rail 21, and rotating the turntable 25 to drive the rotating shaft 24 to rotate. The rotating shaft 24 drives the gear 26 to rotate, and the gear 26 drives the slide plate 22 to move up and down along the tooth groove 23 through meshing, pushing the T-slot 4 to move to facilitate the adjustment of the fence height. The T-slot 4 also pulls the sleeve 8 to slide on the outer wall of the slide rod 9. A display board 3 is provided inside the T-slot 4 to facilitate the display of hazard warnings.

[0026] The connecting mechanism 7 includes a square sleeve 71, an insert plate 72, a spring 73, and a connecting plate 74. The square sleeve 71 is fixedly connected to the right side of the support plate 1, and the insert plate 72 is slidably connected to the top of the square sleeve 71. A spring 73 is provided between the insert plate 72 and the square sleeve 71. The connecting plate 74 is fixedly connected to the left side of the support plate 1. When the two fences are assembled, the connecting plate 74 at one end of the support plate 1 is inserted into the square sleeve 71 fixed on one side of the support plate 1 of the other fence, and the insert plate 72 is pushed to pull the spring 73 upward. When the hole at the top of the connecting plate 74 is parallel to the bottom end of the insert plate 72, it is inserted into the hole under the push of the spring 73, and the fence can be quickly assembled.

[0027] In one embodiment, a turntable 25 is fixedly connected to the outer wall of the rotating shaft 24. A corresponding limiting hole 27 is provided between the outer wall of the turntable 25 and the outer wall of the adjusting rail 21.

[0031] In operation, this invention works as follows: the limiting rod 28 slides through the limiting hole 27 between the turntable 25 and the adjusting rail 21, and the turntable 25 rotates, causing the rotating shaft 24 to rotate. The rotating shaft 24 drives the gear 26 to rotate, and the gear 26, through meshing, drives the sliding plate 22 to move up and down along the tooth groove 23, pushing the T-slot 4 to move to facilitate the adjustment of the fence height. The T-slot 4 also pulls the sleeve 8 to slide on the outer wall of the sliding rod 9. A display board 3 is provided inside the T-slot 4 to facilitate the display of hazard warnings. When two fences are joined together... When the connecting plate 74 at one end of the support plate 1 is inserted into the square sleeve 71 fixed on one side of another fence support plate 1, the insert plate 72 is pushed to pull the spring 73 upward. When the hole at the top of the connecting plate 74 is parallel to the bottom of the insert plate 72, it is inserted into the hole under the push of the spring 73, and the fence can be quickly assembled. By setting a tripod 5 at the bottom of the fence, stable support is provided in flat ground environment. By setting pins 6 on both sides of the tripod 5, the pins 6 can be inserted into the ground for secondary stability.
