The invention discloses an additional tooth pushing asynchronous mechanical anti-theft lock. A rear lock cylinder and a front lock cylinder of the anti-theft lock are completely disconnected, and a sliding hole, a special key hole and an invisible hole are formed in the front lock cylinder; a connection body is mounted in the invisible hole and is separated from the rear lock cylinder; a lock-up hole and a connection hole are formed in the rear lock cylinder; a connection tongue at the rear end of the rear lock cylinder is connected with a linkage mechanism after penetrating through a via hole and then is connected with a spring bolt; a lock-up head is arranged in front of a lock-up spring in a lock-up bearing hole; the lock-up head and an ejection column are mounted in the lock-up hole; a sliding rod in front of the ejection column is mounted in an expansion slot and a sliding hole; the expansion end of the expansion sheet is pressed against a lock-up slot to lock the front lock cylinder; a tooth pushing device and a connection lock-up device are used for locking the front lock cylinder. 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 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 interlocking part and a self-locking part are damaged with savage measures, and burglary prevention can be completely and thoroughly achieved.
