The invention discloses a mechanical tooth-pushing anti-theft lock. A rear lock cylinder of the mechanical tooth-pushing anti-theft lock is completely disconnected with a front lock cylinder, the rear lock cylinder and a connecting body are hidden in an invisible hole, and an expansion piece is disconnected with the rear lock cylinder. A lead hole, a special key hole and the invisible hole are formed in the front lock cylinder, the connecting body is arranged in the invisible hole, and the connecting body is disconnected with the rear lock cylinder. A connecting hole is formed in the front side of the rear lock cylinder, and a via hole for a connecting tongue to be penetrate through is fixed in the rear side of the rear lock cylinder. A sliding rod in front of a guide spring in a sliding hole is arranged in the sliding hole and is installed in an expansion groove and the sliding hole, an extrusion block is embedded onto the sliding rod in an extrusion groove, the expansion end of the expansion piece abuts against a locking groove to lock the front lock cylinder, and a tooth-pushing device and a connecting-locking device lock the front lock cylinder. The mechanical tooth-pushing anti-theft lock integrates mechanical interlocking, invisibility and invisible connection between the front lock cylinder and the rear lock cylinder and enables a theft to be incapable of unlocking an inner supporting lock and turning the rear lock cylinder. Even if the inner supporting lock, a toothed rotating wheel and a rotating corner are damaged by adopting a savage means, the theft can only turn the front lock cylinder, and the rear lock cylinder cannot be turned, so that thorough thievery prevention can be achieved.
