The invention discloses an asynchronous mechanical antitheft lock with an additional side 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 in the front lock cylinder; a connection body is mounted in an invisible hole; the connection body and the rear lock cylinder are disconnected; a locking hole and a connection hole are formed in the rear lock cylinder; a connection tongue at the rear end of the rear lock cylinder penetrates through a through hole and 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 post are mounted in the locking hole; a sliding rod in front of the ejection post is mounted in an expansion groove and a sliding hole; an expansion end of an expansion sheet ejects against a locking groove to tightly lock the front lock cylinder; a side lock device and a rotary locking device are used for tightly locking the front lock cylinder. The asynchronous mechanical antitheft lock with the additional side lock integrates mechanical interlocking, invisibleness and connection invisibleness of the front and rear lock cylinders so that a thief cannot unlock an interlocking device and rotate the rear lock cylinder; even if interlocking and self-locking parts are damaged by using a brutal means, only the front lock cylinder can be rotated and the rear lock cylinder cannot be rotated, so that the complete antitheft effect is realized.
