The invention discloses a mechanical interlocking tooth pushing anti-theft lock. A rear lock cylinder of the anti-theft lock is completely disconnected from a connection body and a front lock cylinder, and an expansion sheet locks the front lock cylinder deadly; a sliding rod is arranged in a sliding hole in the front lock cylinder, and the connection body is mounted in the visible 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 penetrating through a via hole is fixed on the rear surface of the rear lock cylinder; a sliding rod is arranged on the front surface of a guide spring in the sliding hole and 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 extrusion end of the extrusion sheet locks the front lock cylinder in the extrusion slot deadly, and a tooth pushing device and a connection lock-up device lock the front lock cylinder deadly. Invisible mechanical interlocking and invisible connection between the front lock cylinder and the rear lock cylinder are integrated, so that a thief can neither open an external expansion lock-up device nor rotate the rear lock cylinder and can only rotate the front lock cylinder instead of the rear lock cylinder even if an internal supporting lock-up part and the connection body part are damaged with savage measures, and burglary prevention can be completely and thoroughly achieved.
