US12345498 - Grenade device of a toy gun with an adjustable firing muzzle and an adjusting method thereof

A grenade device of a toy gun with an adjustable firing muzzle provided by the present invention comprises: a case, a pressure chamber, a projectile chamber, a switch valve, a launch tube, an outer cover, and a switch cover. The pressure chamber is in the case and receives a pressurized fluid. The projectile chamber is in the case and loaded plural projectile bodies in. The switch valve is between the pressure chamber and the pressure inlet, and is in a starting position to guide the pressurized fluid from the pressure chamber to the projectile chamber. The launch tube has a first and second end. The launch tube cooperates with the pressure chamber and the pressurized fluid to inject the projectile bodies. The outer cover is connected with the case, and has an opening. The switch cover has a through hole and is at a first or second position.
