Two sliders 2 are slidably connected to the inner wall of the frame body 1, and the two sliders 2 are symmetrically arranged. The material of the slider 2 is rubber material, and the toughness of its material facilitates the disassembly and assembly of parts. The shape of the slider 2 is convex, and the outer side walls of the slider 2 are closely attached to the inner side walls of the frame body 1. Three vertical chutes 201 are opened on the opposite sides of the two sliders 2. At the outer openings of the chutes 201, there are second limiting protrusions 202. Bolts 5 are slidably connected to the inner side walls of the chutes 201. Magnet plates 8 are fixedly connected to the inner side walls of the chutes 201 to adsorb and limit the shanks of the bolts 5. Two fixing columns 4 are fixedly connected to the opposite sides of the two sliders 2. A return spring 3 is sleeved between the two fixing columns 4 at the corresponding positions on both sides. U-shaped rotating connecting plates 6 are fixedly connected to the tops of the sliders 2. A rotating plate 7 is rotatably connected to the inner side walls of the U-shaped rotating connecting plates 6. The retaining walls of the two U-shaped rotating connecting plates 6 face each other to block and limit the vertical flipping of the rotating plate 7. By setting the frame body 1, the sliders 2, the return spring 3, the fixing columns 4, and the chutes 201, when connecting the docking parts of two bridges, first slide the shanks of the bolts 5 into the respective chutes 201, and then use the rotating plate 7 to slide the two sliders 2 towards each other.
