The damping rod 3 is connected between the upper ends of the movable buckles 2, and the damping rod 3 is generally an oil pressure damping rod. And two ends of the tension spring 4 are connected between the lower ends of the movable buckles 2. Damping rod 3 includes first damping rod 5, second damping rod 6, first damping rod 5, second damping rod 6 are all installed in damping rod mount pad 7, and its piston shaft 8 all is connected with piston shaft connecting block 9. The damping rod mounting seat 7 is formed by butt joint of a left seat and a right seat, and the two damping rods are fixed between the left seat and the right seat. The rear end of the damping rod mounting seat 7 is hinged to the movable buckle 2 on the same side of the damping rod mounting seat, and the front end of the piston shaft connecting block 9 is hinged to the movable buckle 2 on the same side of the piston shaft connecting block. The movable buckle 2 is connected in a hinged mode, so that the movable buckle can rotate on the damping rod mounting seat 7 and the piston shaft connecting block 9. The piston shaft connecting block 9 and the damping rod mounting seat 7 can synchronously slide in the shell 1. When the self-balancing bidirectional buffer is implemented, the self-balancing bidirectional buffer is arranged at the top of the sliding door to be connected, and stoppers matched with the self-balancing bidirectional buffer are arranged at two ends of the door frame, so that the sliding door can buffer at two sides of the door frame.
