The invention discloses a fingerprint lock anti-theft alarm. The fingerprint lock anti-theft alarm comprises an intra-door handle, an intra-door lock body, a lock cylinder and an anti-theft mechanism, wherein the lock cylinder and the anti-theft mechanism are arranged inside the intra-door lock body; an adjusting block is connected with one end of an ejection rod; the ejection rod is sleeved with a spring; an insertion hole is formed in the intra-door handle; the other end of the ejection rod is connected with a clamping connector; the clamping connector penetrates through the insertion hole and the lock cylinder and then is in contact with a clamping connecting block; a cross joint is installed at the end of the clamping connector; a transition hole is formed in the middle of the clamping connecting block; a blind hole matched with the cross joint is formed in the bottom of the transition hole; a limiting rod matched with a limiting groove is further arranged on the outer circumferential wall of the limiting groove. When the limiting rod is in contact with the limiting position of the limiting groove, the cross joint is aligned with the blind hole, the adjusting block is pressed down at the moment, so that the cross joint is engaged with the blind hole again, and then it is guaranteed that the intra-door lock body can be opened normally. In this way, the time for adjusting the position of the adjusting block constantly is shortened for a user, and it is guaranteed that an anti-theft door can be opened and closed smoothly.
