Road anti-collision column with buffering function

The utility model relates to the technical field of anti-collision columns, and discloses a road anti-collision column with a buffering function, which comprises an embedded base, a lifting hydraulic cylinder, a lifting rod, a first protective column, a second protective column, a connecting block and a large spring, the top of the lifting rod is detachably connected with the second protection column through a connecting block and a large spring, and the top of the second protection column is also detachably connected with the first protection column through a connecting block and a large spring. The first protection column and the second protection column are connected through the large spring, certain buffering elasticity is achieved during collision, the risk that the anti-collision column is damaged during collision is reduced, the overall damage of the anti-collision column caused by collision can be effectively reduced, meanwhile, the first protection column and the second protection column can be detac
