The invention relates to a window breaker, and belongs to the technical field of mechanical engineering. The window breaker comprises a shell, a fixing plate, a percussion device and a supporting frame. The shell is mounted on the upper portion of the fixing plate through a bolt mounted on the shell, one end of the supporting frame is mounted on the lower portion of the fixing plate, the percussion device is mounted at the other end of the supporting frame, and the shell internally comprises a limiting head, a limiting spring, a window breaking needle, a piston plate and a cartridge case. A square groove is formed in the front portion of the shell, one end of the limiting spring is mounted in the square groove, the limiting head is connected to the other end of the limiting spring, the piston plate is mounted in the shell, the window breaking needle is mounted in the middle of the piston plate, the lower portion of the cartridge case is mounted on the fixing plate, and the upper portion of the cartridge case is mounted on the lower portion of the shell. The percussion device comprises a firing pin, a fixing ring, a pull rod, a trigger magnet, a firing spring, a limiting plate, a connecting rod, an iron block and a supporting rod. According to the window breaker, recycling can be realized; glass can be efficiently broken through, and the window breaking effect is improved; the structure is simple, cost is low, and application and popularization are facilitated.
