Abstract

The utility model discloses a lock for a built-in mortise lock, which comprises a housing. A lock core is arranged at each of the two ends of the housing, wherein, one lock core is an idling lock core, and the other lock core is a normal lock core (without idling), or both of the lock cores are idling lock cores; and each lock core is connected with a shifting block. When the lock is locked, the idling lock core is in the state of preoperation; when a foreign matter or a lockpick is inserted in the lock, a front lock liner can rotate at random, but the lock can not be unlocked; only when the matched key is used, the front lock liner and a rear lock liner can rotate together, and the shifting blocks are driven to rotate to unlock or lock the lock. Compared with the prior lock, the utility model has higher performance of preventing technical unlocking and destructive lock picking because of the adoption of the idling lock core.
