Combined coded lock

The invention discloses a combined coded lock. The combined coded lock comprises an internal handle assembly, an external handle assembly and a lock body and further comprises an engagement-and-disengagement mechanism arranged on the external handle assembly and a drive mechanism for driving the engagement-and-disengagement mechanism. The lock body comprises a lock shell, lock tongues and a linkage mechanism for driving the lock tongues to move. The external handle assembly can selectively drive the linkage mechanism through the engagement-and-disengagement mechanism. The internal handle assembly is connected with the linkage mechanism and can directly drive the linkage mechanism. The combined coded lock has the beneficial effects that a fingerprint code lock body and a touch-tone mechanical coded lock body are combined to serve as a double-driver of the coded lock, the potential safety hazards brought by a traditional mechanical lock are avoided, and the safety of the coded lock is improved. Furthermore, the combined coded lock is further provided with a handle reversing gear, and mounting is flexible; and the linkage mechanism is in cooperation with the double-drive mechanism and the engagement-and-disengagement mechanism to form a complete structure, and the demands of people on the high safety of anti-theft locks, convenient and fast use, flexible mounting and the like can be well met.
