The invention discloses an anti-theft locking device which comprises an inner door handle, a lock body as well as a lock cylinder and an anti-theft mechanism which are arranged in the lock body, a regulating block is connected with one end of a push rod, a spring is sleeved on the push rod, a jack is formed in the inner door handle, the other end of the push rod is connected with a clamping head, the clamping head penetrates through the jack and the lock cylinder and is then in contact with a clamping block, a cross joint is arranged at the end of the clamping head, a transition hole is formed in the middle part of the clamping block, a blind hole matched with the cross joint is formed in the bottom of the transition hole, and the external circumference wall of a limiting slot is also provided with a limiting rod matched with the limiting slot. When the limiting rod is in contact with the extreme position of the limiting slot, the cross joint is aligned with the blind hole, at the moment, the regulating block is pressed to ensure that the cross joint and the blind hole are re-engaged, and then the lock body can be normally unlocked, so that the time for debugging the position of the regulating block continuously by a user is reduced, and a security door can be successfully opened or closed.
