A limiting block 12 is installed on the outer surface of the bottom end of the column 4, and a cross bar 13 is inserted on the inner surface of the limiting block 12. A slot 14 is fixedly opened inside the cross bar 13, and a limiting slot 15 is opened inside the slot 14. A spring 16 is installed at the bottom end of the anti-collision tube 10, and an arc block 17 is fixedly installed at one end of the spring 16. By rotating the anti-collision tube 10, the spring 16 and the arc block 17 are driven to separate from the inner surface of the limiting slot 15, and the anti-collision tube 10 can be replaced.
[0025] See also Figure 2-5 Both ends of the insertion column 7 are "T"-shaped, and the shape of the mounting block 8 is "T"-shaped, which increases the connection effect between the insertion column 7 and the mounting block 8, and can be quickly replaced. The anti-collision tube 10 and the rotating tube 11 are distributed in a linear array on the surface where the cross bar 13 is placed, which increases the force structure of the guardrail and enables the guardrail to shift when it is hit.
