Positioning long grooves 20 are provided on both the inner top wall and inner bottom wall of the rectangular long plate 17. Positioning long holes 21 are provided on both the left inner side and right inner side of the rectangular long plate 17. A support column 13 is fixedly connected to the bottom of the rectangular long plate 17. A support bottom plate 12 is fixedly connected to the bottom of the support column 13. A first limiting disk 10 is fixedly connected to the outer surface of the support bottom plate 12. A plurality of triangular indicating grooves 11 are provided on the top of the first limiting disk 10. The positioning long cylinder 14 is movably installed inside the positioning long hole 21. The positioning long rod 16 is movably installed inside the positioning long groove 20. One end of the return spring 24 is fixedly installed on the inner wall of one end of the support groove 25. The other end of the return spring 24 is fixedly connected to a support long rod 2. A handle 3 is fixedly connected to one side of the support long rod 2. A limiting long plate 18 is fixedly connected to the other side of the support long rod 2. A support block 1 is fixedly connected to the rear side of the support long rod 2.

Through the setting of the warning sign main body 15, this device can warn drivers and pedestrians at the highway construction site. Through the settings of the support groove 25, the first installation component, the first positioning component, the second positioning component and the first limiting component, the first installation component can limit the warning sign main body 15 and can be disassembled. The first positioning component and the second positioning component can both position the warning sign main body 15. The first limiting component can limit the second positioning component. This device can replace the warning sign by means of clamping, making the way to replace the warning sign of this device very easy and making this device convenient to replace the warning sign.

[0028] In use, the initial state of the device is as follows: The limit long plate 18 is located inside the positioning long cylinder 14, one end of the mounting screw 4 is located inside the mounting long plate 5, and the limit screw rod 6 is threadedly connected to the thread groove 27. During the process of highway construction, when it is necessary to use this device to warn drivers and pedestrians at the highway construction site, under the action of the warning sign body 15, this device can be used to warn drivers and pedestrians at the highway construction site. When it is necessary to replace the warning sign, pull the handle 3 in the direction away from the loop-shaped long plate 17, so that the support long rod 2 and the support block 1 both move in the direction away from the loop-shaped long plate 17, so that the return spring 24 is stretched in the direction away from the loop-shaped long plate 17, so that the limit long plate 18 slides along the positioning long cylinder 14 in the direction away from the loop-shaped long plate 17, so that the limit long rod 22 and the limit cross plate 23 both slide along the loop-shaped long plate 17. When pulling the handle 3 in the direction away from the loop-shaped long plate 17 to the maximum distance, the limit long rod 22 and the limit cross plate 23 both slide along the loop-shaped long plate 17 to the maximum distance, so that the limit long plate 18 is disconnected from the positioning long cylinder 14. Keep the state of pulling the handle 3 in the direction away from the loop-shaped long plate 17 to the maximum distance unchanged, and push the warning sign body 15 forward along the rear side of the loop-shaped long plate 17, so that the warning sign body 15 slides forward along the loop-shaped long plate 17, so that the positioning long cylinder 14 slides forward along the positioning long hole 21, so that the positioning long rod 16 slides forward along the positioning long groove 20. When the warning sign body 15 completely slides out of the loop-shaped long plate 17, the positioning long cylinder 14 slides out of the positioning long hole 21, and the positioning long rod 16 slides out of the positioning long groove 20, and release the handle 3, the return spring 24 changes from the stretched state to the compressed state, so that the limit long plate 18 is located in the positioning long hole 21. At this time, the warning sign body 15 can be taken out of the loop-shaped long plate 17, so that the warning sign body 15 can be replaced, so that this device can replace the warning sign. During the process of replacing the warning sign of this device, this device can realize the replacement of the warning sign by means of clamping, so that the way of replacing the warning sign of this device can be very easy, so that this device can conveniently replace the warning sign.

The bottom of the second support plate 26 is fixedly connected with a second limit plate 19. A plurality of threaded grooves 27 are formed on the outer surface of the second limit plate 19. The top of the first support plate 8 is fixedly connected with a support ring 9. A limit screw 6 is commonly threadedly connected inside the support vertical plate 7 and inside the first support plate 8. The limit screw 6 is threadedly connected with the threaded grooves 27. A mounting screw 4 is threadedly connected inside the mounting long plate 5.

And when the angle of this device needs to be adjusted, this device can adjust the angle by its own rotation, making it convenient to adjust the angle of this device.

[0030] In use, before using this device to warn drivers and pedestrians at the highway construction site, rotate the mounting screw 4 so that the mounting screw 4 rotates along the mounting long plate 5 and moves towards the ground near the highway construction site. When the mounting screw 4 rotates along the mounting long plate 5 and moves towards the ground near the highway construction site to the maximum distance, the mounting screw 4 is inserted into the ground at the highway construction site. At this time, the first support plate 8 can be installed on the ground at the highway construction site. After installing the first support plate 8 on the ground at the highway construction site, during the process of using this device to place a warning sign at the highway construction site to warn drivers and pedestrians, when the angle of this device needs to be adjusted, rotate the limit screw 6 so that the limit screw 6 is disengaged from the thread groove 27 and one end of the limit screw 6 is located inside the first support plate 8. Rotate the support column 13 so that the loop-shaped long plate 17, the warning sign main body 15, the positioning long tube 14, the positioning long rod 16 and the handle 3 all rotate, so that the support bottom plate 12 rotates along the first support plate 8, so that the first limit plate 10 rotates along the support ring 9, so that the triangular indicating groove 11 can rotate with the rotation of the first limit plate 10, so that the second support plate 26 and the second limit plate 19 both rotate along the first support plate 8, so that the angle of the warning sign main body 15 can be changed. When the angle of the warning sign main body 15 is the required angle and when the thread groove 27 corresponds to the limit screw 6, the tip of the triangular indicating groove 11 corresponds to the limit screw 6. Rotate the limit screw 6 so that the limit screw 6 is threadedly connected to the thread groove 27. At this time, the angle of this device can be adjusted. And under the action of the first limit plate 10, when the thread groove 27 corresponds to the limit screw 6, the tip of the triangular indicating groove 11 can face the limit screw 6, so that the thread groove 27 can be indicated to correspond to the limit screw 6. During the process of adjusting the angle of this device, this device can install the second rotating assembly on the ground at the highway construction site. And when the angle of this device needs to be adjusted, this device can adjust the angle by its own rotation, so that this device can be conveniently adjusted in angle.

[0031] In this embodiment, the four corners of the support bottom plate 12 are all arc-shaped, and the outer diameter of the return spring 24 is smaller than the diameter of the support groove 25.
