The tire fender 1 is put on the support 2, the pressure plate 3 is rotated and locked by the locking assembly, and the sidewall of the tire fender 1 facing the chord side is pressed against the chord side by the pressure plate, thereby realizing reliable fixation of the tire fender 1. Because the tire fender 1 is fixed by compression, the locking assembly of the tire fender 1 does not shake when the ship is sailing or colliding, and the wear of the locking assembly is small; and because the pressure plate 3 is located between the two sidewalls of the tire fender 1, it directly contacts and squeezes the tire fender 1 during a collision, and most of the collision energy is absorbed by the deformation of the tire fender 1 itself, and the tire fender 1 does not move significantly, and thus does not pull. Because the locking assembly wears less and there is no problem of pulling the tire fender 1, frequent replacement can be avoided during use, thereby reducing costs.

[0021] Specifically, the support 2 is fixed on the chord side by welding, and the pressure plate 3 is connected to the support 2 by a hinge, so that the pressure plate 3 and the support 2 are rotatably connected.
