A launch vehicle includes an air pump, an injection valve, a connecting
member, a trigger, and a projectile. Thus, the launch vehicle is operated
on the ground and is also operated in a hand-held manner, thereby
enhancing the amusement effect of the launch vehicle. In addition, the
user only needs to hold the air pump and the trigger so as to launch the
projectile easily and conveniently in an energy-saving manner, thereby
facilitating the user operating the launch vehicle. Further, the launch
vehicle has a simplified construction to perform the hand-held launching
function, thereby decreasing the costs of fabrication. Further, the
launch vehicle is further provided with a safety device to prevent the
trigger from being triggered unintentionally to protect the user's
safety.
