Anti-collision telescopic structure for highway bridge

The utility model relates to the field of civil engineering, and discloses an anti-collision telescopic structure for highway bridges, which comprises two symmetrically arranged supporting columns, grooves are formed in the upper ends of the sides, close to each other, of the two supporting columns, a rotating rod is rotationally sleeved with the two grooves jointly, the rod wall of the rotating rod is sleeved with a first anti-collision plate, and the two ends of the rod wall of the rotating rod are sleeved with torsional springs. The two ends of the torsional spring are fixedly connected with the supporting columns and the first anti-collision plate correspondingly, buffer grooves are formed in the lower ends of the sides, close to each other, of the two supporting columns correspondingly, push plates are arranged on the inner surfaces of the two buffer grooves in a contact mode correspondingly, and the ends, close to each other, of the two push plates penetrate through the buffer grooves and extend to the
