The invention discloses an interlocking mechanical and additional tooth-pushing anti-theft lock. A rear lock cylinder of the interlocking mechanical and additional tooth-pushing anti-theft lock is completely disconnected from a front lock cylinder and a connector; a sliding rod is arranged in a sliding hole inside the front lock cylinder, the connector is mounted in an invisible hole, and an extrusion block is fixedly arranged on the sliding rod; a connection tongue at the rear end of the rear lock cylinder passes through a through hole, is 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 mounted in a locking hole, and the sliding rod in front of the ejection column is mounted in an extrusion groove and the sliding hole; the expansion end of an expansion sheet extends into the extrusion groove and locks the front lock cylinder, and a tooth-pushing device and a connection locking device lock the front lock cylinder. The interlocking mechanical and additional tooth-pushing anti-theft lock integrates the functions of mechanical interlocking, invisibility and connection invisibility of the front lock cylinder and the rear lock cylinder, so that a thief cannot open an interlocking device and cannot rotate the rear lock cylinder; even if interlocking and self-locking parts are damaged in a barbarous way, only the front lock cylinder can be rotated while the rear lock cylinder cannot be rotated, and therefore a thorough anti-theft effect can be achieved.
