Hardness-variable flexible cable

The invention discloses a hardness-variable flexible cable, and relates to a cable. The hardness-variable flexible cable comprises a support core, wherein the side wall of the support core is provided with a plurality of strands of wire cores arranged along the circumferential direction of the support core, a buffer layer is arranged between an outer sheath and a filling layer and comprises a buffer strip and a foaming rubber strip, a plurality of first buffer bags and second buffer bags are arranged in the buffer strip, the first buffer bags are filled with buffer gas, and the second buffer bags are filled with phase-change materials. According to the invention, the buffer layer can improve the rigidity of the cable in the use state of the cable, so the cable meets rigidity requirements in a use process, the cable is protected from being damaged easily in the use process, the cable has certain flexibility in the non-use state of the cable, the cable can bear certain extrusion force in transportation, draggin
