Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of trigger mechanism for fire-fighting bomb for forest fuse, including triggering shell 1, trigger head 2, bottom plate
3, spring 4, frizzen 5 and touching contact pin 6 are fired, wherein compression groove 102, triggering are equipped at the top center of triggering shell 1
First 2 are installed in compression groove 102, and the upper surface of trigger head 2 is higher than the upper surface of triggering shell 1, at the center of compression groove 102
Equipped with spring groove 103, fires spring 4 and be installed in spring groove 103；103 bottom of spring groove, which is dug, through-hole, and frizzen 5 is installed on
In through-hole；Bottom plate 3 is installed in compression groove 102, the upper end be it is discoid, connect with the lower end of trigger head；It inserts 5 upper end of frizzen
Enter to fire in spring 4, and is connect with the lower end of bottom plate 3；Touching contact pin 6 is set to 5 lower end of frizzen, touches the lower end of contact pin 6
Setting thorn hair priming device.
