Safety hammer

Abstract

The invention discloses a safety hammer. The safety hammer comprises a long-rod-shaped hammer body. An electric striking device is arranged at one end of the hammer body, the other end of the hammer body is in the shape of a circular truncated cone, and protrusions are arranged on the end surface of the circular truncated cone. The electric striking device comprises a power source, a switch, a hammer head, a spring, a cam and a motor. One side of the hammer head is in contact with the cam, and the cam is rotatably connected with the hammer body and driven by the motor. The spring sleeves the hammer head, and the two ends of the spring are correspondingly in contact with the other sides of the hammer body and a baffle block. An opening for the hammer head to penetrate through is arranged atone end of the hammer body. In the natural state, the hammer head is located in the hammer body, and the hammer head can reciprocate relative to the hammer body when the motor is started; and the motor, the power source and the switch are electrically connected through wires. The safety hammer is provided with the electric striking device, after the power switch is pressed, the hammer head can reciprocate relative to the hammer body to assist the force application, and even people with small force can quickly break a piece of window glass.

Description

technical field [0001] The invention relates to a safety hammer. Background technique [0002] Existing car safety hammers have simple structure and single function, relying entirely on the user's own strength to hit the glass window; when the vehicle suddenly fires, explodes, poisonous gas, falls into water and other critical moments, if the user's strength is small, it may not be able to break the glass window Thicker window glass escape.
