The safe window striking device comprises a shell, a cam and a breaking hammer, the cam and the breaking hammer are installed in the shell, the shell is fixed to vehicle window glass, the shell is provided with a guide groove perpendicular to a vehicle window, the breaking hammer is installed in the guide groove and can move in the direction of the guide groove, and the breaking hammer is sleeved with a blocking ring; a containing cavity of a cam is further formed in the shell, the cam is locked in the shell through a pin shaft and a nut, and the cam can rotate along the pin shaft; the automobile window glass wiper further comprises a handle used for being held, one end of the handle extends into the shell to be connected with the cam, the other end of the handle is connected to a handle supporting block in a clamped mode, and the handle supporting block is fixed to the automobile window glass. And an avoiding groove is formed in the shell. The cam mechanism is adopted, a reliable window striking device is provided for people in a vehicle, meanwhile, when the cam mechanism is used, stress applied to vehicle window glass is rapidly increased in a gradual mode, and the stress just reaches the breaking stress value of the vehicle window glass.
