[0025] Reference Figure 1 and Figure 3 A fixing assembly 101 is provided on both sides of the bottom of the placement rack 7, and the fixing assembly 101 includes two springs 1011. Limiting grooves 17 are provided on both sides of the bottom of the placement rack 7. The two springs 1011 are fixedly connected in the two limiting grooves 17 respectively. The rear sides of the two springs 1011 are fixedly connected with a clamping block 1012, and the front sides of the two clamping blocks 1012 are fixedly connected with a pull rod 1013. The left and right sides of the bottom of the warning sign 9 are provided with clamping grooves 11, and the two clamping blocks 1012 are respectively embedded and connected in the two clamping grooves 11.

[0026] Specifically, the spring 1011 provides elastic support for the block 1012, and the limit groove 17 provides a position limit for the spring 1011 to ensure that the spring 1011 will not exceed a predetermined range. The block 1012 is used to be embedded in the slot 11 to fix the warning sign 9. The pull rod 1013 is connected to the front side of the block 1012 and is used to operate or adjust the position of the block 1012. The slot 11 is located on the left and right sides of the bottom of the warning sign 9 and is used to be embedded with the block 1012 to fix the warning sign 9 on the placement rack 7.

[0027] Working principle: rotating the turntable 2 drives the bevel gear 1 3 to rotate, and the bevel gear 1 3 drives the meshing bevel gear 2 4 to rotate, and the bevel gear 2 4 drives its top threaded rod 5 to rotate, and the left slider 6 is threadedly connected to the threaded rod 5. The rotation of the threaded rod 5 drives the right slider 6 to move up and down in the slide groove 13, driving the placement plate 7 and the warning sign 9 inside it to achieve the beneficial effect of lifting. The raised warning device not only indicates the existence of the construction area, but also can be used to guide the driver to take specific actions, such as slowing down or following the designated lane, which helps to optimize traffic flow and reduce the probability of accidents. Pulling the pull rod 1013 drives the block 1012 to retract. When it reaches the limit groove 17, the block 1012 disengages from the grooves 11 on both sides of the bottom of the warning sign 9, and the warning sign 9 can be slid out of the second slide groove 18 through the handle 8, and the warning sign 9 with a different warning slogan can be replaced. The new warning sign 9 is placed in the middle of the placement rack 7 through the second slide groove 18, and the pull rod 1013 is loosened. The spring 1011 releases the tension and pushes the block 1012 to be embedded in the grooves 11 on both sides of the bottom of the warning sign 9, and the new warning sign 9 can be fixed. When the warning sign 9 does not match the actual road conditions, it will mislead and confuse the driver. By replacing the warning sign 9 in time, the probability of this happening can be reduced, thereby reducing the risk of traffic chaos and accidents.
