1. A floating fastener with shock-absorbing structure, comprising:
a base comprising a cylindrical portion, an accommodating space formed through said cylindrical portion, a protruding abutment ring and an inner ring provided on an inner wall of said cylindrical portion, and a bottom plate extending outwards from a bottom side of said cylindrical portion;
a fixing element comprising a head, a shank extending downwards from said head and passing through said accommodating space of said base, a locking portion extending downwards from said shank, and a stop portion located on a top side of said locking portion around said shank for stopping against a bottom side of said inner ring;
a flexible liner attached with a bottom surface thereof to a top surface of said bottom plate, said flexible liner comprising a perforation placed outside said cylindrical portion of said base and a positioning embedding portion protruding upwards from a top side thereof around said perforation of said flexible liner and placed in a first fixing hole of a preset first plate;
a positioning tube comprising a tube body formed with a perforation through the inside and a protruding ring portion expanding outward from a bottom side of said tube body; and
a buffer pad comprising a perforation inside and a ring groove set in an inner wall thereof and positioned on said protruding ring portion of said positioning tube;
wherein the assembly structure of said positioning tube and said buffer pad is placed outside said cylindrical portion of said base through said perforation of said positioning tube from top to bottom to form a positioning; said buffer pad and said flexible liner are flexibly supported on opposing upper and lower surfaces of said preset first plate respectively, so as to absorb and buffer the stress transmitted to said preset first plate when the floating fastener vibrates.
