A first telescopic rod 9 is fixed between the two first slide rails 1, and a second telescopic rod 10 is fixed between the two second slide rails 5. The first telescopic rod 9 and the second telescopic rod 10 are convenient for telescoping, so as to adjust the distance between the two first slide rails 1 and the distance between the two second slide rails 5.

[0025] As a further implementation scheme of the above technical scheme: a hollow fixed block 11 is fixedly provided at the bottom end of the two first slide rails 1, and a first forward and reverse motor 12 is fixedly provided inside the two fixed blocks 11. The top ends of the transmission shafts of the two first forward and reverse motors 12 are respectively fixedly connected to the bottom ends of the two first threaded rods 2, so that the first forward and reverse motors 12 can drive the first threaded rod 2 and the second threaded rod 6 to rotate.

[0026] As a further implementation scheme of the above technical scheme: the two first slide rails 1 are slidably connected with sliders 13 inside, and one side of the two sliders 13 is provided with a mounting plate 14. The inside of the two mounting plates 14 is provided with a plurality of threaded holes, so that the sliders 13 can easily drive the mounting plates 14 to move.

[0027] During specific implementation: the fixing block 11 is placed at the specified position, and the second slide rail 5 is placed at the top of the first slide rail 1. The second threaded rod 6 is rotated so that the limit block 7 can be placed in the limit groove 3, and the first fixing seat 4 is aligned with the second fixing seat 23. The first fixing seat 4 and the second fixing seat 23 are fixed together by the fixing bolt 8, so that the first slide rail 1 and the second slide rail 5 are fixed together, and the first threaded rod 2 and the second threaded rod 6 are fixed together. At this time, the billboard is fixed to the mounting plate 14 by bolts, and the fixing block 11 is fixed to the ground by bolts. The spacing between the two first slide rails 1 and the spacing between the two second slide rails 5 can be adjusted by the first telescopic rod 9 and the second telescopic rod 10, so that the spacing between the two mounting plates 14 can be adjusted, so that the device can fix billboards of different sizes, and the first forward and reverse motor 12 is started. The first forward and reverse motor 12 rotates, thereby driving the first threaded rod 2 to rotate. The rotation of the first threaded rod 2 will drive the limit block 7 to rotate, thereby driving the second threaded rod 6 to rotate, so that the first threaded rod 2 and the second threaded rod 6 rotate synchronously. , so that the slider 13 moves from the first threaded rod 2 to the second threaded rod 6, and finally the slider 13 moves to the top of the second slide rail 5, so that the mounting plate 14 and the billboard move up. When the billboard is used and the device needs to be disassembled, the first forward and reverse motor 12 is started to reverse, thereby driving the first threaded rod 2 and the second threaded rod 6 to reverse, thereby driving the slider 13 to move down, thereby driving the mounting plate 14 and the billboard to move down. When the mounting plate 14 moves to the first threaded rod 2, the first forward and reverse motor 12 is turned off, the bolts between the mounting plate 14 and the billboard are removed, the billboard is disassembled, and the fixing bolts 8 are removed. At this time, the first fixing seat 4 is separated from the second fixing seat 23, so that the first slide rail 1 can be separated from the second slide rail 5, and the first threaded rod 2 can be separated from the second threaded rod 6, so that the overall height of the device is reduced, and the storage space is reduced. The storage space of the device can be further reduced by contracting the first telescopic rod 9 and the second telescopic rod 10, so that a smaller vehicle can also transport the device, reducing the transportation difficulty of the device and improving the transportation efficiency of the device.

[0028] As a further implementation scheme of the above technical scheme: a support plate 15 is fixedly provided on one side of the two sliders 13 , and a pair of connecting blocks 16 are fixedly provided on the top of one side of the two support plates 15 , so that the support plates 15 are convenient for supporting the connecting blocks 16 .

[0029] As a further implementation scheme of the above technical scheme: a rotating shaft 22 is rotatably connected between the two connecting blocks 16 of each group, and a fixing rod 17 is fixedly arranged on the sides of the two rotating shafts 22. One end of the two fixing rods 17 is respectively fixedly connected to the top end of one side of the two mounting plates 14, so that the rotating shaft 22 can drive the mounting plates 14 to rotate.

[0030] As a further implementation scheme of the above technical scheme: a slide groove is provided at the bottom end of one side of the two support plates 15, and movable blocks 18 are slidably connected inside the two slide grooves. One side of the two movable blocks 18 is hinged with a support rod 19, and the top ends of the two support rods 19 are respectively hinged to the bottom ends of one side of the two mounting plates 14, so that the movable blocks 18 can easily drive the support rods 19 to move.

[0031] As a further implementation scheme of the above technical scheme: the interiors of the two movable blocks 18 are both threadedly connected with screw rods 20, and the sides of the two screw rods 20 are respectively rotatably connected to the interiors of the two support plates 15, so that the screw rods 20 can easily drive the movable blocks 18 to move up and down.

[0033] During specific implementation: when the height of the billboard is high, it is not easy to observe the content on the billboard when standing under the billboard, which reduces the warning effect of the billboard. When the slider 13 moves to the top of the second slide rail 5, the second forward and reverse motor 21 is started at this time. The second forward and reverse motor 21 rotates to drive the screw rod 20 to rotate, thereby driving the movable block 18 to move downward. When the movable block 18 moves downward, it will drive the support rod 19 to move downward. The support rod 19 pulls the mounting plate 14, so that the mounting plate 14 rotates downward along the rotating shaft 22. The stability of the rotating shaft 22 during rotation is improved by the connecting block 16. The fixing rod 17 facilitates the connection between the mounting plate 14 and the rotating shaft 22. The billboard is fixed on the mounting plate 14. When the mounting plate 14 rotates downward, the billboard tilts downward, so that the angle of the billboard can be adjusted, so that the content on the billboard can be clearly observed when approaching the billboard, which is convenient for improving the warning effect of the billboard.
