The invention discloses an anti-theft lock. The anti-theft lock comprises a grooved lock cylinder rotation core, blades, a movable element, return springs and a movable spring which are matched with the lock cylinder rotation core, an engineering key and a householder key, wherein a plurality of the blades are arranged in the lock cylinder rotation core; an inclined-surface structure is arranged at the tail end of the householder key, a notch is formed in the upper side of each blade and a boss is arranged at the lower side of each blade; each return spring is arranged between the inner wall of the lock cylinder rotation core and the corresponding boss; a trigger mechanism point and press-fit teeth on the movable element are comprised; the press-fit teeth are used for carrying out press-fit on the notches in a part of the blades; the return springs are tightly pressed, so that a part of the blades is in an unlocked state; when the householder key enters the lock cylinder rotation core and the inclined-surface structure supports the trigger mechanism point to a vertex, the movable spring pushes forwards the movable element, so that a part of the blades to expands under the elastic actions of the return springs and is in a locked state, and the engineering key is invalid. The invention discloses an anti-theft lock capable of preventing the householder key from being copied through the engineering key.
