Abstract: A pneumatic ball launcher includes a tube, a ball pathway unit, a push unit, a holding unit, an airway unit and a pneumatic unit. The ball pathway unit is used for connecting one end of the tube and wrapping part of a ball channel of the tube. The push unit includes a push bar, a slide base, a first driver and a second driver. The holding unit, detachably connected with the push unit, is used for holding the ball pushed by the push bar. The airway unit is connected with the holding unit. The pneumatic unit includes a valve mechanism, a pneumatic cylinder and a gas tank. When the valve mechanism opens to allow the gas tank to discharge into the holding unit via the airway unit, the ball held by the holding unit would be ejected out of the tube.
