The invention discloses a mechanical asynchronous spring-free additional antitheft lock. The rear lock cylinder and the front lock cylinder of the mechanical asynchronous spring-free additional antitheft lock are completely disconnected from each other; a connector is hidden in a hiding hole; the front lock cylinder is locked by an expansion piece; a guide hole, a special key hole and the hiding hole are formed in the front lock cylinder; the connector is arranged in the hiding hole; the connector is disconnected from the rear lock cylinder; a connecting hole is formed in the front face of the rear lock cylinder, and a connecting tongue is fixed on the rear face of the rear lock cylinder and goes through a via hole; a sliding rod is mounted in a sliding hole and arranged in front of a guide spring in the sliding hole; the sliding rod is further mounted in a squeezing groove and the sliding hole; a squeezing block is embedded in the sliding rod in the squeezing groove; the expansion end of the expansion piece is located in the squeezing groove to lock the front lock cylinder; the front lock cylinder is locked by a rotary locking device. The mechanical asynchronous spring-free additional antitheft lock is integrated with mechanical interlocking, hiding, and connection hiding of the front and rear lock cylinders, and therefore, the breaking of inner support locking and the rotating of the rear lock cylinder cannot be realized simultaneously by a theft; even though the inner support locking and the connector parts are damaged violently, only the front lock cylinder can be rotated and the rear lock cylinder cannot be rotated, and consequently, a complete and thorough anti-theft effect is achieved.
