Guiding projection 350 starts to rotate along guide chute 220 after entering release section 223 under the effect on inclined-plane, thereby drive hammer 300 to start rotation, the projection of unblanking on hammer 300 rotates to the chute 121 of unblanking on base 100, as shown in figure 12, in figure, the direction of arrow represents the rotation direction of hammer 300 with respect to base 100.
In the time that shell is pressed onto, the guiding projection on hammer 300 moves to release section end; The projection of unblanking on hammer 300 also all screws out, and enters the chute of unblanking of base 100. Now hammer 300 completes release, clashes into fast glass for vehicle window and complete brokenly window action under the promotion of main spring 400.
After completing brokenly window, external force disappears, and under the promotion of compressed back-moving spring 500, shell 200 starts to move to initial position. Meanwhile, under the promotion of main spring 400 guiding projection 350 of hammer 300 in releasing section 223 junction with reset section 224, owing to unblanking projection 340 still in the chute of unblanking in base 100 220 on hammer 300 now, hammer 300 cannot rotate; Can only drive with shell 200 and continue to slide to initial position by guiding projection 350. When the projection 350 of unblanking on hammer 300 rises from unblanking after chute 121 of base 100 completely, main spring 400 elastic force that hammer 300 is still compressed promote, guiding projection 350 is subject to elastic force to promote the reset section along shell 200 224 to slide, drive hammer 300 to turn round, the projection of unblanking on hammer 300 is turned to above the locking projection of base 100, complete locking. So far, device completes a complete working cycles, enters holding state, re-presses shell 200 and can break window operation next time.
When the utility model work, applicant finds, hammer 300 opposite shell 200 have rotation, and main spring 400 is arranged between hammer 300 and shell 200, if the two ends of main spring 400 are fixedly connected on respectively on hammer 300 and shell 200, when hammer 300 opposite shell 200 are rotated, to there is circumferential distortion in spring, this distortion will certainly stop the rotation of hammer 300, thereby unfavorable guiding projection 350 slips into and skids off release chute along smooth rotation and the release chute projection of guide chute 220, now can only one end of main spring 400 be pushed against to the bottom of accommodating chamber, the other end pushes against the bottom of blind hole 210 and places, when now hammer 300 opposite shell 200 are rotated, can overcome between main spring 400 and the bottom of accommodating chamber, frictional force between the bottom of main spring 400 and blind hole 210, main spring 400 is synchronously rotated with hammer 300, when rotation, only need overcome between main spring 400 and the bottom of accommodating chamber, frictional force between the bottom of main spring 400 and blind hole 210, but, due to: 1., there is joint main spring 400 ends, between this joint and the bottom of accommodating chamber, between the bottom of this joint and blind hole 210, reciprocatingly slide and can produce cut, this cut stops the unitary rotation of main spring 400, 2., main spring 400 is compressed, its elastic restoring force is very large, main spring 400 is pressed on the bottom of accommodating chamber, the bottom of blind hole 210 by this elastic restoring force, because frictional force is directly proportional to pressure, therefore under this operating mode, frictional force is also very large. in order to overcome the resistance problem of hammer 300 main spring 400 in the time that base 100 rotates, the bottom of accommodating chamber is provided with the first swivel bearing, the inner ring of the first swivel bearing or outer ring are fixed on the bottom of accommodating chamber, correspondingly, the outer ring of the first swivel bearing or inner ring are fixedly connected with an elastic tip of main spring 400,, by the first swivel bearing, the sliding friction between main spring 400 and the bottom of accommodating chamber is become to rolling friction, thereby reduce main spring 400 to impact of the present utility model.
