The invention discloses a mechanical linkage main lock. The mechanical linkage main lock comprises a lock shell, and a lock tongue, a lock bolt, a lock bolt driving mechanism, a pull rod and a pull rod driving mechanism which are mounted on the lock shell, wherein a spring column is fixed on the lock shell, and is coated with a lock tongue return spring; one end of the lock tongue return spring is butted against the spring column, and the other end of the lock tongue return spring is butted against the lock tongue; the lock bolt driving mechanism is used for driving the lock bolt to transversely extend and retract; and the pull rod driving mechanism is used for driving the pull rod to open and close longitudinally. The mechanical linkage main lock further comprises a wrong operation preventing mechanism for preventing the locking when a door is not closed completely; the lock bolt fits a lock bolt groove formed in a door frame or a passive door when the lock is used; and the longitudinally opened pull rod fits a lock point mounted on the door frame to realize the locking of the main lock. The mechanical linkage main lock performs dual fixation for the door through the lock bolt and the pull rod, so that the antitheft performance is good; and the mechanical linkage main lock can be singly used as a door lock of a door entering security door, or can be used as a security lock of an indoor door by fitting a secondary lock.
