The invention discloses a tooth-pushing-added asynchronous mechanical anti-theft alarm lock. A rear lock cylinder of the tooth-pushing-added asynchronous mechanical anti-theft alarm lock is completely separated from a front lock cylinder. A slide hole, a specially-matched key hole and a hiding hole are formed in the front lock cylinder. A connection body is installed in the hiding hole and is separated from the rear lock cylinder. A locking hole and a connection hole are formed in the rear lock cylinder. A connection tongue part of the rear end of the rear lock cylinder penetrates through a passing hole to be connected with a linkage mechanism and then connected with a spring bolt. A locking head is arranged in front of a locking spring in a locking and bearing hole. The locking head and an ejecting column are installed in the locking hole. A sliding rod in front of the ejecting column is installed in an expansion groove and the slide hole. The expansion end of an expansion piece is ejected in a locking groove to lock the front lock cylinder. The front lock cylinder is locked through a tooth pushing device and a rotation locking part. The mechanical interlocking, the hiding and the connection hiding of the front lock cylinder and the rear lock cylinder are integrated, and a thief can not open an interlocking device or rotate the rear lock cylinder. The thief can only rotate the front lock cylinder and can not rotate the rear lock cylinder even after an interlocking part and a self-locking part are damage by barbaric means, and the thorough thievery prevention can be achieved.
