Beschreibung
Zusammenfassung:	The utility model relates to a ball throwing and gun throwing device which comprises a cylinder body, a piston and a lower connector. A plurality of through grooves are evenly formed in the side wallof one end of the lower connector in the circumferential direction of the axis, the through grooves do not make contact, and the other ends of the through grooves are not communicated with the other end of the lower connector. The end, provided with the elastic claw, of the lower connector is inserted into the cavity of the cylinder and coaxially and fixedly connected with the cylinder. The pistonis coaxially positioned in the cavity of the cylinder body; one end of the piston is inserted into the elastic claw and can be mutually limited and clamped with the elastic claw after being inserted,so that the elastic claw is positioned between the bulge and the inner wall of the cylinder, the three are mutually pressed and contacted, and the other end of the piston is connected with the innerwall of the cylinder through
