Embodiment 1
[0011] Please refer to figure 1 , the safety hammer of the present invention has a hammer head 1, a hammer body 2, a support rod 3, a fixed plate 4, a hammer surface 5, a main spring 6, an outer sleeve 7, a hammer tail 8, an upper bamboo protrusion 9, a fixed spring 10, and a trigger 11 , Lower bamboo shoot 12, hammer handle 13, fixed pin 14, support spring 15 and through hole 16. Wherein the hammer head 1 is a hard alloy with a tip, and the hammer body 2 is a metal barrel with both ends closed and through holes. The fixed plate 4 is a relatively thick metal disc, and the hammer tail 8 is a relatively thick metal block. The function of the fixed pin 14 is to ensure that the outer sleeve 7 can slide back and forth along the hammer body 2 without falling off from the hammer body 2, supporting The function of the spring 15 is to maintain a certain gap between the hammer surface 5 and the front end surface of the hammer body 2 . The hammer surface 5 and the front end of the hamm...

The invention discloses safety equipment used in a vehicle, in particular to a safety hammer, comprising a hammer head, a hammer body, a main spring, a hammer tail, a trigger and a hammer handle, wherein the hammer head is a hard alloy with a pointed end; the hammer tail is a massive metal block; and the hammer body is in a metal drum shape. When in use, a user firstly handholds the hammer handle, stretches the hammer tail backwards, and waves the hammer handle to hammer glass, therefore, the trigger is triggered, and the main spring extends to push the hammer head to strike the car window glass surface and form resultant force with impact force generated in waving the hammer handle so as to break the car window glass into pieces. The safety hammer in the invention has the advantages of simple structure, safe and convenient use and obvious effect, and can be widely used in occasions such as vehicles, ships and the like.
Description
technical field [0001] The invention relates to safety equipment used in vehicles, in particular to a safety hammer. Background technique [0002] Existing bus window glass is relatively large, on the one hand can expand the passenger field of view, on the other hand can be used as an escape exit when the bus door cannot be opened when the bus encounters a critical situation. In order to be able to smash the window glass when necessary, a safety hammer is equipped inside the passenger car. The existing safety hammer is a metal column with pointed or flat heads at both ends and a hammer handle in the middle. During the use of the safety hammer, if the user is a woman, the elderly, a child, the disabled or an injured person with low strength, it may not be possible to use the existing safety hammer to break the thicker window glass . Due to the limitation of the space range in the passenger car, the volume of the safety hammer cannot be too large, and the handle of the hamm...
