Handrails 9 for facilitating the pushing of the base 7 are fixedly installed at the left and right opposite positions on the upper edge side of the base 7.

[0027] Please refer to Figure 4 , in this embodiment, the first adjustment component includes a slide rail box 401, a threaded rod 402, a slide block 403 and a first driving motor 404. A threaded rod 402 for rotation is provided inside the slide rail box 401. A slide block 403 for sliding is sleeved on the outer side of the threaded rod 402. An output shaft is provided on the first driving motor 404. The output shaft of the first driving motor 404 passes through the upper end of the slide rail box 401 and extends to the inside to drive the threaded rod 402 to rotate. By setting the first driving motor 404 to drive the threaded rod 402 to rotate, the threaded rod 402 can drive the slide block 403 to slide up and down along its surface, thereby driving the LED display screen 1 to move synchronously to adjust it to different heights.

[0028] Please refer to Figure 5, in this embodiment, the second adjustment component includes a turntable 501, a rotating shaft 502, a second driving motor 503, a support base 504 and a sliding column 505. A rotating shaft 502 for rotation is fixedly connected to the middle of the lower end of the turntable 501. A second driving motor 503 for driving the rotation of the rotating shaft 502 is provided at the lower end of the rotating shaft 502. The second driving motor 503 is embedded and installed in the middle of the upper end of the support base 504. The second driving motor 503 drives the turntable 501 to rotate synchronously by driving the rotation of the rotating shaft 502. Five groups of sliding columns 505 for supporting the turntable 501 are fixedly installed around the upper end side of the support base 504. An arc-shaped groove 506 for sliding connection with the sliding column 505 is formed on the lower end side of the turntable 501. By setting the second driving motor 503 to drive the rotating shaft 502 to drive the turntable 501 to rotate synchronously, the arc-shaped groove 506 at the lower end of the turntable 501 slides along the sliding column 505, thereby driving the upper LED display screen 1 to rotate synchronously to adjust the angle.

[0029] Please refer to Figure 6 , in this embodiment, the support component includes a support frame 601, an adjustment bolt 602 and a support block 603. An adjustment bolt 602 for controlling the up and down movement of the support block 603 is provided at one end of the support frame 601 away from the base 7. The adjustment bolt 602 passes through the upper end of the support frame 601 and extends to the lower end to control the support block 603. By setting the adjustment bolt 602, it is convenient to adjust the position of the support block 603 according to different usage requirements. The lower end of the adjustment bolt 602 is fixedly connected to a support block 603 for supporting the adjustment bolt 602. Six groups of mounting holes 604 for mounting and fixing the support block 603 are formed around the upper end side of the support block 603. When encountering uneven ground, the support block 603 can be installed and fixed at the corresponding position through the mounting holes 604 on the support block 603 to maintain the stability of the support block 603.

[0030] When working, first push the handrail 9, so that the roller 8 drives the base 7 to move, and push the device to the corresponding position;

[0031] Then support the base 7 through the support component to keep it stable. Turn the adjustment bolt 602 to drive the support block 603 to move downward until the support block 603 tightly adheres to the ground. The support block 603 can also be installed and fixed at the corresponding position through the mounting holes 604 on the support block 603;

[0032] After that, adjust the LED display screen 1 to the appropriate height through the first adjustment component. Drive the threaded rod 402 to rotate through the first driving motor 404, so that the threaded rod 402 drives the slider 403 to slide up and down along its surface, and then drives the LED display screen 1 to move synchronously to adjust it to the corresponding height;

[0033] Then, the LED display screen 1 is adjusted to an appropriate angle through the second adjustment component. The second driving motor 503 drives the rotating shaft 502 to drive the turntable 501 to rotate synchronously, so that the arc-shaped groove 506 at the lower end of the turntable 501 slides along the sliding column 505, thereby driving the upper LED display screen 1 to rotate synchronously and adjusting it to an appropriate angle;

[0034] During the operation of the device, corresponding texts are displayed on the LED display screen 1 for warning and reminder. The warning lamp 2 and the warning sticker 3 are used for auxiliary warning and reminder. The LED display screen 1, the warning lamp 2 and the warning sticker 3 cooperate with each other from different angles for reminder, and the warning effect is better.

[0035] Through the above steps, by setting the existing highway construction safety warning device into an adjustable structure, its height and angle can be adjusted according to different usage requirements to achieve the best warning effect. It is more flexible and applicable than traditional devices, and the warning effect is better. By setting the first adjustment component, the height of the LED display screen 1 can be adjusted. By setting the second adjustment component, the angle of the LED display screen 1 can be adjusted. By setting the support component, the base 7 can be supported when the LED display screen 1 is working to maintain its stability, so as to solve the problem that the existing highway construction safety warning device is usually set as a fixed structure, which is not convenient to adjust according to different scenarios and different usage requirements, and the warning effect has limitations.
