The invention discloses a novel car anchoring device for a container shore bridge. The device comprises a car panel; an anchoring base is mounted at the top of the car panel; a girder is arranged at one end of the car; a girder panel is arranged on the top surface of the girder, and is fixed with a bracket; a second hinge is arranged at the top of the bracket, and is hinged with a connecting rod and a handle; an anchoring plate hinge base is fixedly mounted on one side of the girder, and is hinged with an anchoring plate; the bottom surface of the head part of the anchoring plate is butted against the anchoring base; the upper surface of the head part of the anchoring plate is connected with a connecting rod through a hinge base; and a first hinge capable of bending is arranged in the middle position of the connecting rod. The car anchoring device is changed from an insertion plate type to a swing type; the anchoring base is mounted on the car panel; the anchoring plate is mounted on a girder web through a hinge shaft; a set of connecting rod mechanism is provided; a handle locking pin shaft and a detecting limiter are arranged on the anchoring base; and drivers can stand the top surface of the girder to realize retraction and release of the anchoring plate through carrying the connecting rod handle after each operation, so that the operation is convenient, safe and reliable.
