The invention discloses an interlocking mechanical tooth-pushing anti-theft lock. A rear lock cylinder of the interlocking mechanical tooth-pushing anti-theft lock is completely disconnected with a front lock cylinder and a connecting body, a sliding rod is arranged in a sliding hole formed in the front lock cylinder, the connecting body is installed in an invisible hole, and an extrusion block is fixed to the sliding rod. A connecting tongue at the rear end of the rear lock cylinder penetrates through a via hole to be connected with a linkage mechanism and then is connected with a lock tongue. A locking head is arranged in front of a locking spring in a locking bearing hole, the locking head and an ejection column are installed in the locking hole, and the sliding rod in front of the ejection column is installed in an extrusion groove and the sliding hole. The expansion end of an expansion piece extends into the extrusion groove to lock the front lock cylinder, and a tooth-pushing device and a connecting-locking device lock the front lock cylinder. The interlocking 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 interlocking device and turning the rear lock cylinder. Even if interlocking and self-locking portions 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.
