Further, the damping element 130 may be a steel wire bundling rope loop (the specific structure is disclosed in chinese patent nos. CN2182147Y and CN 2848937Y), or a steel ring, a rubber ring or a composite material ring, etc., and when it is impacted by a moving object, it will enter the elastic-plastic deformation stage, and a large amount of kinetic energy becomes the elastic-plastic deformation work of the steel wire bending, and becomes energy in the mutual friction between the steel wires to be dissipated.
