Abstract

The utility model discloses a multifunctional safety hammer for vehicles. The multifunctional safety hammer is characterized in that the safety hammer comprises a casing with a front opening, and a top bushing arranged at the front end of the casing in a sliding manner, wherein a first spring is arranged between the top bushing and the inner bottom surface of the casing in a butt-connection manner; a shift block and a first guide rib are integrally arranged on the inner circumference of the casing; a location block and a guide groove are integrally formed on the outer circumference of the top bushing; the guide groove is in slide fit with the first guide rib; the location block butts against the rear surface of the shift block; a support breaking column is arranged in the casing; and an elastic telescopic mechanism for pushing the support breaking column is arranged between the support breaking column and the top bushing. When an emergency occurs, the safety hammer can break the window of a vehicle only by pressing the safety hammer on the window and ejecting the support breaking column by the elastic force of the second spring. Accordingly, the safety hammer can be conveniently used in traffic facilities, such as a crowded bus, without requiring large space for waving the arm, thereby helping the passengers escape in time.
