The invention discloses a mechanical interlock lock-up anti-theft lock. A rear lock cylinder of the anti-theft lock is completely separated from a connection body and a front lock cylinder; an expansion sheet locks the front lock cylinder; a sliding rod is arranged in a sliding hole in the front lock cylinder, and the connection body is mounted in an invisible hole; an extrusion block is fixed on the sliding rod; a connection hole is formed in the front surface of the rear lock cylinder, and a connection tongue fixed on the rear surface of the rear lock cylinder penetrates through a via hole; the sliding rod in front of a guide spring in the sliding hole is mounted in the sliding hole; the sliding rod is mounted in an extrusion slot and the sliding hole; an extrusion block is embedded into the sliding rod in the extrusion slot; the expansion end of the expansion sheet locks the front lock cylinder in the extrusion slot, and a connection lock-up device locks the front lock cylinder. Mechanical interlocking, hiding and invisible connection of the front lock cylinder and the rear lock cylinder are integrated, so that a thief can neither open an interlocking device nor rotate the rear lock cylinder and can only rotate the front lock cylinder instead of the rear lock cylinder even if an inner supporting lock-up part and the connection body part are damaged with savage measures; a complete and thorough anti-theft effect is achieved.
