The invention discloses a mortise lock. The mortise lock comprises a lock shell, a main lock tongue, a main lock tongue return spring, a trigger, a trigger return spring, a main lock tongue positioning plate, a slide plate and a safety block, wherein the main lock tongue positioning plate has two support legs; the first support leg fits a limiting block for locking the main lock tongue; the slide plate is slidingly arranged on the main lock tongue; the safety block has a clamping hook; and after the main lock tongue shrinks back into the lock shell, the safety block rotates, and the clamping hook fits the end part of the slide plate, so that the slide plate moves to the trigger direction to butt against the trigger so as to prevent the return of the trigger. When the main lock tongue shrinks into the lock shell, the safety block rotates to enable the clamping hook to fit the second end of the slide plate, the slide plate is butted against the trigger, and the safety plate moves to enable a drop preventing surface to fit a clamping block so as to prevent the main lock tongue from sliding outside the lock shell; and in the state, an inclined tongue fitting the trigger can freely shrink and extend, the main lock tongue is always locked, and the mortise lock can serve as a passage lock.
