The spring 12 is sleeved on the outside of the limit rod 10, and the two ends of the spring 12 are respectively fixedly connected to the limit ring 11 and the base 7. When the limit rod 10 is pulled from the outside of the base 7, the limit rod 10 will move out of the limit rod 10 outside the first positioning block 13, releasing the limit on the first positioning block 13. After the limit rod 10 is released, the limit rod 10 will return to its original position under the pull of the spring 12, insert into the limit hole 14, and lock the first positioning block 13.

[0034] In a preferred embodiment, a limiting groove 18 is defined on the side of the second positioning block 17 facing the limiting rod 10, and the limiting groove 18 is slidably connected to the limiting rod 10. After the limiting rod 10 is released and inserted into the limiting hole 14 to limit the first positioning block 13, it continues to be inserted into the limiting groove 18 outside the second positioning block 17. When the connecting seat 6 is dragged, a portion of the limiting rod 10 remains inserted into the limiting groove 18, ensuring a stable fit between the first positioning block 13 and the limiting rod 10.

[0035] In a preferred embodiment, a bolt plate 9 is provided at the lower end of the base 7, which is fixedly connected to the left and right sides of the sign body 1. A through hole is provided on the bolt plate 9. When the base 7 is installed on a road surface where it is inconvenient to bury the base 7, pins or bolts can be assembled on the bolt plate 9 and the base 7 can be reinforced by driving the pins or bolts into the ground.

[0036] In order to prevent the limit rod 10 and the spring 12 outside the limit rod 10 from being wetted by rainwater during rainy days, thereby causing rust, in a preferred embodiment, a shield 8 is provided above the limit rod 10. The shield 8 is sleeved on the outside of the connecting seat 6 and is fixedly connected to the connecting seat 6. When the connecting seat 6 is fixed to the top of the base 7, the shield 8 sleeved on the outside of the connecting seat 6 will be in close contact with the upper end surface of the base 7. When it rains, rainwater will fall on the shield 8, which protects the limit rod 10.

[0037] How this application works:

[0038] The lifting bracket is arranged between the sign body 1 and the connecting seat 6. The connecting seat 6 and the base 7 support the sign body 1 through the lifting bracket. The lifting bracket is used to adjust the height of the sign body 1 to ensure that the sign body 1 can be effectively presented in the field of vision of passers-by. During installation, the first positioning block 13 at the lower end of the connecting seat 6 is inserted into the second slot 16 at the top of the baffle 8, and the second positioning block 17 in the second slot 16 is inserted into the first slot 15 opened at the bottom of the first positioning block 13. The double limiting method can ensure that the connecting seat 6 will not shake horizontally after installation, and the stability is better. After installation, the spring pin rod on the outside of the base 7 will be inserted into the limiting hole 14 opened on the outside of the first positioning block 13 to limit the up and down movement of the first positioning block 13. The pin rod limiting method is adopted, and the sign body 1 and the lifting bracket are easy to replace.
