The invention discloses a tooth pushing asynchronous mechanical anti-theft lock. A rear lock cylinder and a front lock cylinder are completely disconnected, a sliding hole, a special key hole and an invisible hole are formed inside the front lock cylinder, a connecting body is installed inside the invisible hole, and the connecting body and a rear lock cylinder are disconnected; a locking hole and a connecting hole are formed inside the rear lock cylinder and a connecting bolt at the rear end of the rear lock cylinder penetrates a passing hole to be connected with a linkage mechanism and then is connected with a lock bolt; a locking head is arranged at the front of a locking spring inside a locking bearing hole, the locking head and a support column are installed inside the locking hole, a sliding rod at the front of the support column is installed inside an expansion groove and a sliding hole; an expansion end of an expansion piece is abutted against and presses inside a locking groove to lock the front lock cylinder, and a tooth pushing device and a connecting locking device lock the front lock cylinder. According to the tooth pushing asynchronous mechanical anti-theft lock, mechanical interlocking, invisibility and connection invisibility of the front lock cylinder and the rear lock cylinder are integrated into a whole, a burglar cannot open an interlocking device and rotate the rear lock cylinder, namely, only the front lock cylinder can rotate and the rear lock cylinder cannot rotate after interlocking and self-locking portions are damaged through barbaric means, and burglar prevention can be completely achieved thoroughly.
