Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0018] The utility model provides a kind of blow gas and remove waste material piston cylinder as Figs. 1-3 It is shown, including:

[0019] Cylinder barrel 1, one end of the cylinder barrel 1 is connected with cylinder base 2, the other end is connected with front cover 3, the cylinder barrel 1 is equipped with piston seat 4 and the one end of piston seat 4 is connected with piston rod 5, one end of the piston rod 5 is slidably penetrated through front cover 3, the cylinder base 2 is equipped with connecting groove 6 and the cylinder base 2 side is communicated with connecting groove 6 with air inlet pipe 7, gas source is supplied into cylinder barrel 1 by the air inlet pipe 7, to make gas source promote piston rod 5 movement and carry out blow gas by the blow gas channel 8 equipped in piston rod 5 interior.

[0020] The connecting place of cylinder barrel 1 and cylinder base 2 and front cover 3 is equipped with sealing gasket 9, and the connecting place is sealed by sealing gasket 9, to prevent gas from easily leaking from the tiny gap between cylinder barrel 1 and cylinder base 2, front cover 3.

[0021] The piston seat 4 and the piston rod 5 are sleeved with a spring 10, the two ends of the spring 10 are connected with the front cover 3 and the piston seat 4 respectively, and the spring 10 can release the elastic potential energy to push the piston seat 4 and the piston rod 5 back to the initial position.

[0022] One end of the piston rod 5 is provided with an external thread 11, and a nut 12 and a punch pin 13 are threadedly connected on the surface of the external thread 11, the punch pin 13 is threadedly connected with the piston rod 5, and the connection mode is simple and reliable, and the punch pin 13 is convenient to install and replace.
