The invention discloses an asynchronous mechanical additional shrapnel-free anti-theft lock. A back lock cylinder is completely disconnected from a front lock cylinder. A sliding hole, a specially matched key hole and a hidden hole are formed in the front lock cylinder. A connector is installed in the hidden hole and is disconnected from the back lock cylinder. A locking hole and a connection hole are formed in the back lock cylinder. A connection tongue at the back end of the back lock cylinder penetrates through a through hole to be connected with a linkage mechanism and then connected with a lock tongue. A locking head is arranged in a locking bearing hoe in the front of a locking spring, the locking head and a support pillar are installed in the locking hole, and a sliding rod located in the front of the support pillar is installed in an extrusion groove and the sliding hole. The expansion end of an expansion piece extends into the locking groove to lock the front lock cylinder, and a turning block locks the front lock cylinder in an oblique groove and an oblique locking groove. The asynchronous mechanical additional shrapnel-free anti-theft lock integrates mechanical interlocking invisibility and front lock cylinder and the back lock cylinder connection invisibility, and thieves cannot opening the interlocking device or turn the back lock cylinder, or even if they damage the interlocking portion and the self-locking portion through brute force, they can only turn the front lock cylinder but cannot turn the back lock cylinder, and therefore the thorough anti-theft effect is achieved.
