Further, described percussive cap is in T shape.
The beneficial effects of the utility model are: the utility model fixes explosion head by the first opening part at housing, impacting body is installed in the inner chamber of housing, and extension spring is connected between impacting body with explosion head, during use, hold housing on the other hand, explosion head is against the broken window point place on case hardened glass, then pull impacting body to certain distance, suddenly loose one's grip, by the restoring force of extension spring, impacting body moment is impelled to hit to explosion primary drying at a high speed, the tip of explosion head is made to produce powerful impulsive force to case hardened glass, thus case hardened glass is smashed, this similar knocks in use hammer the structure that chisel carries out brokenly window, the safety hammer of case hardened glass structure is directly knocked relative to similar use hammer, first the directing reach of its explosion is connected on brokenly on window point, accurate positioning, impulsive force is concentrated, broken window is effective.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic perspective view of the utility model mounting structure;
Fig. 2 is cutaway view of the present utility model.
Detailed description of the invention
See figures.1.and.2, safe life-saving pen of the present utility model, comprise housing 1, explosion 2, impacting body 3 and extension spring 4, inner chamber 11 is provided with in described housing 1, inner chamber 11 two ends are respectively equipped with the first opening 111 and the second opening 112, described explosion 2 is fixed on the first opening 111 place, its front end is exposed housing 1 and is provided with tip 21, its rear end is stretched in inner chamber 11, described impacting body 3 is installed in inner chamber 11 movably, described extension spring 4 is arranged on explosion between 2 and impacting body 3, and its two ends are separately fixed on explosion 2 and impacting body 3.When the utility model uses, hold housing 1 on the other hand, explosion 2 is against the broken window point place on case hardened glass, then pull impacting body 3 to certain distance, suddenly loose one's grip, by the restoring force of extension spring 4 be connected between impacting body 3 and explosion 2, impel impacting body 3 moment at a high speed to explosion 2 impact, tip 21 pairs of case hardened glasss of explosion 2 are made to produce powerful impulsive force, thus case hardened glass is smashed, this similar knocks in use hammer the structure that chisel carries out brokenly window, the safety hammer of case hardened glass structure is directly knocked relative to similar use hammer, its explosion 2 is connected to brokenly on window point always, accurate positioning, impulsive force is concentrated, broken window is effective.
In the present embodiment, described explosion adopts following structure to fix between 2 and housing 1: described explosion 2 is provided with cone portion 22, this cone portion 22 is positioned at tip 21 rear, its cross-sectional area near tip 21 one end is greater than its cross-sectional area near second opening 112 one end, described first opening 111 is suitable with described cone portion 22, not only can locate the center of explosion 2, the application force of explosion 2 pairs of housings 1 can be reduced simultaneously, extend service life of housing 1, and it is mobile in inner chamber 11 to limit explosion 2.The rear end of described explosion 2 is provided with the first outside thread 23 for fixedly sleeved extension spring 4, the external diameter of the first outside thread 23 is greater than the internal diameter of extension spring 4, can use fixture that extension spring 4 is poured the first outside thread 23 during production, fixed by the elastic deformation of extension spring 4 and the first outside thread 23, the inwall of described inner chamber 11 is provided with for stopping the step 113 that extension spring 4 is deviate from from the first opening 111, because extension spring 4 and explosion 2 is fixed together, the stop of step 113 pairs of extension springs 4 simultaneously, limit explosion 2 movement outside housing 1, because cone portion 22 matches with the first opening 111, to limit explosion 2 mobile in inner chamber 11 again, from can and explosion 2 is fixed on the first opening 111 of housing 1.Certainly, above-mentioned just preferred embodiment, the fixed sturcture of described explosion between 2 and housing 1 also can adopt screw connection structure to replace, namely described explosion 2 is provided with connection outside thread, described first opening 111 is provided with and the negative thread being connected outside thread and coordinating, although this structure is simple, when using, the application force of explosion 2 pairs of housings 1 is large, easily causes housing 1 to damage.
Further, be conveniently fixed on impacting body 3 by the other end of extension spring 4, described impacting body 3 is provided with the second outside thread 31 for fixedly sleeved extension spring 4, and the two ends of extension spring 4 are all fixed by outside thread, convenient for production.
Further, described housing 1 is fixed with cutting blade 6, the outside of the corresponding cutting blade 6 of housing 1 is provided with protection handle 12, the space for passing for cutting object is formed between described protection handle 12 and cutting blade 6, when safety strap is stuck and cannot extracts, this cutting blade 6 can be utilized to be cut off.Described protection handle 12 both can prevent cutting blade 6 from exposing and the user that damages, and person easy to use can grip housing 1.In the present embodiment, described cutting blade 6 is injection-moulded in housing 1, and without the need to assembling, in cutting process, cutting blade 6 can not rock by housing 1 relatively, good cutting effect.
Further, described impacting body 3 is fixedly connected with away from one end of explosion 2 and is convenient to the percussive cap 5 that hand pulls impacting body 3.Preferably, described percussive cap 5 is in T shape, and user's middle finger and the shoulder T-shaped on percussive cap 5 of thumbscrew can pull impacting body 3, easy to operate.Described percussive cap 5 is provided with the taper location division 51 of inserting inner chamber 11 near one end of the second opening 112, described second opening 112 matches to locate impacting body 3 with taper location division 51, this structure is due to the directional tagging of second opening 112 pairs of taper location divisions 51, even if impacting body 3 is toward there being a little axis direction departing from explosion 2 during explosion 2 direction resilience, also auto modification can be realized, ensure that the center of explosion 2 is aimed at the center of impacting body 3 all the time, ensure strength under shock.
Certainly, the utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should within its protection domain.
