However, during the grenade launching process, the existing launcher is prone to cause damage to the drone or other aircraft due to the recoil force generated when the grenade is launched, affecting the aircraft's mid-air flight and making it impossible to accurately strike the target. Moreover, most of the existing launchers have one launcher corresponding to one grenade warhead, which greatly limits the aircraft's ammunition load. Summary of the invention

[0012] Furthermore, an inclined surface is formed at the end of the fixed surface, and the angle between the inclined surface and the roulette wheel surface is the same as the angle between the power storage edge and the roulette wheel surface.

[0013] Furthermore, the inertia hammer head includes an impact surface, and the impact surface can strike the outer end of the striker.
