The invention discloses a limiting interior door safety lock. A ringing device is arranged at one side adjacent to an installation soleplate, a driving shaft and a locking shaft are installed in a driving shaft sleeve and a locking shaft sleeve which are intersected with each other, threads on the locking shaft are engaged with a gear disc on the driving shaft, a presser leg on the lower top end of the locking shaft stretches out of the bottom of an outer shell, a drive rod is inserted in an open slot of the outer shell to be connected with the driving shaft, the locking shaft is driven to stretch in the vertical direction by the swinging of the drive rod, when the drive rod is shifted downwards, a locking part which is connected with the drive rod is tightly connected with a locking column in a buckling manner, the presser leg on the lower top end of the locking shaft tightly pushes against the floor, a door body is locked, an interior door outer lock is prevented from being opened, and a door opening prompting function and an antitheft effect can be realized. After a free end of the drive rod is transferred upwards, a magnetic connecting part of the drive rod is matched with a door stopper seat in a suction manner, a door stopper function is realized, so that the door body can be fixed.
