The invention provides a tempered glass breaking device. The tempered glass breaking device comprises a long cylindrical air barrel, the back end of the air barrel is closed, and a rotary cover is arranged at the front end of the air barrel in a matched mode. A sliding plug capable of freely sliding along the inner wall of the air barrel is arranged inside the air barrel; a fulcrum bar coaxial with the sliding plug is connected to the front end of the sliding plug, a screw coaxial with the fulcrum bar is connected to the front end of the fulcrum bar, and an attacking component with a pointed cone is connected to the front end of the screw; a screw hole matched with the screw is formed in the middle of the rotary cover; a limiting ring with the inner diameter smaller than the outer diameter of the screw is arranged at the position, close to the front end of the air barrel, inside the air barrel, so that the sliding plug is limited; when the sliding plug reaches the position of the limiting ring, the air pressure inside the air barrel closed through the sliding plug is larger than one standard atmospheric pressure. The tempered glass breaking device is simple in structure and convenient to use; in theory, any hard tempered glass can be broken.
