When the second spring 26 is in a relaxed state, the limiting arc surface 2322 abuts against the side wall of the limiting shaft 243. When the firing pin 23 is not subjected to external force, the firing pin 23 limits itself through the cooperation of the limiting arc surface 2322 and the limiting shaft 243. When the hammer 4 strikes the firing pin 23, the firing pin 23 moves into the step hole 242 and strikes the primer of the grenade in the magazine 31. In order to reduce the friction between the protective cover 423 and the power storage edge 2121, the power storage edge 2121 is rounded, and the fixed surface 211 includes an inclined portion 2111. The angle between the inclined portion 2111 and the surface of the wheel disc 2 is the same as the angle between the power storage edge 2121 and the surface of the wheel disc 2, so as to facilitate the movement of the lever 422 and the protective cover 423 from the wheel disc 2 to the power storage guide rail 21.
