The invention discloses an asynchronous mechanical anti-theft lock with an additional tooth pushing device. A rear lock cylinder is completely disconnected from a front lock cylinder; a sliding hole, a special key hole and an invisible hole are formed in the front lock cylinder, and a connector is mounted in the invisible hole and disconnected from the rear lock cylinder; a locking hole and a connecting hole are formed in the rear lock cylinder, and a connecting tongue at the rear end of the rear lock cylinder is sequentially connected with a linkage mechanism and a lock tongue after penetrating through a via hole; a locking head is arranged in front of a locking spring in a locking bearing hole, the locking head and a support pillar are mounted in the locking hole, and a sliding rod in front of the support pillar is mounted in a squeezing groove and the sliding hole; an expansion end of an expansion sheet extends into the squeezing groove to lock the front lock cylinder, and the front lock cylinder is further locked through the tooth pushing device and a connection locking device. The lock achieves the integration of mechanical interlocking, invisibility, and invisible connection between the front lock cylinder and the rear lock cylinder, so that a thief cannot open an interlocking device or rotate the rear lock cylinder; even if the thief damages the interlocking device and a lock pillar savagely, only the front lock cylinder can be rotated, and the rear lock cylinder cannot be rotated, so that complete theft prevention is achieved.
