The invention discloses an additional side chain asynchronous mechanical anti-theft lock. A rear lock cylinder and a front lock cylinder of the anti-theft lock are completely disconnected; a sliding hole, a specially matched keyhole and an invisible hole are formed in the front lock cylinder, a connecting body is arranged in the invisible hole, and the connecting body is disconnected with the rear lock cylinder; the rear lock cylinder is provided with a lock-up hole and a connecting hole, a connecting tongue at the rear end of the rear lock cylinder passes through a via hole and is connected with a linkage mechanism, and then the connecting tongue is connected with a lock-tongue; a lock-up head is arranged in front of a lock-up spring which is in a lock-up bearing hole, the lock-up head and a support pillar are arranged in the lock-up hole, and a sliding bar in front of the support pillar is arranged in an expansion slot and the sliding hole; an expansion end of an expansion slice is pressed on a lock-up slot to dead lock the front lock cylinder, and a side chain device and a connecting lock-up device dead lock the front lock cylinder. According to the additional side chain asynchronous mechanical anti-theft lock, the mechanical interlocking, the invisibility and the invisible connection between the front and the rear lock cylinders are integrated to be a whole, and a thief can not open an interlocking device and rotate the rear lock cylinder; even if an interlocking portion and a self-locking portion are damaged by barbaric means, the front lock cylinder can be only rotated, and the rear lock cylinder does not rotate, so that anti-theft function is achieved completely and thoroughly.
