The invention discloses an asynchronous mechanical locking anti-theft lock. A rear key cylinder of the lock is completely disconnected with a front key cylinder of the lock, a sliding hole, a special key hole and an invisible hole are formed in the front lock key cylinder, a connection body is installed in the invisible hole and disconnected with the rear lock key, locking holes and a connection hole are formed in the rear key cylinder, a connection tongue at the rear end of the rear key cylinder penetrates a through hole to be connected with a linkage mechanism followed by a lock tongue, locking heads are arranged in front of locking springs in locking bearing holes, the locking heads and a support column are installed in the locking holes, a sliding rod in front of the support column is installed in an extrusion slot and the sliding hole, an expansion end of an expansion sheet extends into the extrusion slot to deadly lock the front key cylinder, and a connection locking device deadly locks the front key cylinder. According to the asynchronous mechanical locking anti-theft lock, mechanical interlocking, invisibility and connection of the front and rear key cylinders are integrated, so that thieves cannot open an interlocking device or rotate the rear key cylinder; that is, even if thieves damage interlocking and cylinder columns with a brutal means, only the front key cylinder can be rotated, the rear key cylinder cannot be rotated, so that an anti-theft function is completely and thoroughly served.
