The torsion arms at both ends of the torsion spring 43 are hung on the notch 1241. The torsion arm in the middle of the torsion spring 43 is overlapped on the hammer seat 421. When the lever 422 passes the top of the power storage edge 2121, the hammer body 42 can rotate around the rotating shaft 41 driven by the torsion spring 43 and strike the firing pin 23, thereby triggering the primer of the grenade in the magazine 31 through the firing pin 23 to launch the grenade.

[0038] In order to rotate the roulette wheel 2, convex teeth 22 are uniformly extended from the circumference of the roulette wheel 2, and a reduction motor 133 is fixedly provided under the supporting portion 13.
