The invention belongs to the field of design of connecting structural parts, and particularly relates to a single-face connecting fastener capable of being quickly and repeatedly installed, which comprises a bolt body, an external thread section, a polished rod section and a bolt head in sequence in the axial direction, and a cross-shaped groove is embedded in the bolt head; The lining is tubularand matched with the bolt body, the lining sequentially comprises a regular polygon inner groove section, a cylindrical inner groove section and a protruding shoulder in the axial direction, a stop groove is formed in the outer edge of the protruding shoulder in the axial direction, and a strip-shaped through hole is formed in the lining of the regular polygon inner groove section in the axial direction; The nut is matched with the lining and the bolt body, and an elastic piece is installed on the nut. And a transition inclined plane is arranged at one end, close to the cylindrical inner groove section, of the strip-shaped through hole and is matched with the elastic sheet. According to the single-face connecting fastener capable of being quickly and repeatedly installed, the problem of single-face connection between structures is solved, meanwhile, the fastener can be repeatedly disassembled, assembled and used on the premise that the structure is not damaged, and only a single connecting hole position needs to be drilled in the installation process.
