The invention discloses a stealing-opening prevention type lock capable of preventing a room door from being opened in a stealing manner by an unlocking tool. A lock cylinder and a spring bolt are arranged in a lock body in sequence from left to right; a transverse sliding chute is formed in the left end of the spring bolt; a longitudinal driving slot is formed in the right end of the spring bolt; a sliding block is connected to the sliding chute of the spring bolt through an elastic clutch mechanism; a screw hole is formed in the sliding block; a screw at the right end of the lock cylinder is connected to the screw hole in the sliding block; a switch board is arranged in a driving slot; a knob is connected with the switch board through a rotating shaft. When the lock cylinder is rotated by a key, the lock cylinder drives the sliding block and the spring bolt to move left and right through the screw and the screw hole so as to lock and unlock the lock; when the lock is locked and the key is pulled out, the lock cylinder locks the sliding block and the spring bolt through the screw and the screw hole. When the knob is used for locking and unlocking the lock, under the action of the elastic clutch mechanism, the switch board can independently drive the spring bolt to move; when the knob drives the switch board to rotate leftwards, the lock can be unlocked; when the knob drives the switch board to rotate rightwards, the lock can be locked, and the spring bolt is locked.
