The invention discloses a mechanical additional tooth pushing anti-theft lock. A rear lock cylinder and a front lock cylinder of the mechanical additional tooth pushing anti-theft lock are completely disconnected and are hidden in an invisible hole together with a connection body; an expansion sheet and a locking column lock the front lock cylinder deadly; a lead hole, a special key hole and an invisible hole are formed in the front lock cylinder; the connection body is arranged in the indivisible hole; the connection body is disconnected from the rear lock cylinder; 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 mounted in a sliding hole is arranged on the front surface of a guide spring in the sliding hole and mounted in an expansion slot and the sliding hole; the expansion end of the expansion sheet is pressed against the lock-up slot to lock the front lock cylinder; 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 the external expansion lock-up device and a locking column are damaged with savage measures, and burglary prevention can be completely and thoroughly achieved.
