Beschreibung
Zusammenfassung:	The utility model relates to an air cylinder, comprising a cylinder barrel, a front end cover, a rear end cover, a piston, a piston rod and a sealing piece, wherein the rear end cover is provided with a first air hole and a second air hole, and the first air hole is directly communicated with the rear end of the cylinder barrel. The cylinder barrel is provided with gas pipelines, the outlet of one end of each gas pipeline is communicated with the second air hole, and the outlet of the other end of each gas pipeline is communicated with the front end of the cylinder barrel. On the one hand, gas enters the cylinder barrel from the first air hole to push the piston and the piston rod to move forwards; on the other hand, gas enters the cylinder barrel from the second air hole by the gas pipelines to push the piston and the piston rod to contract backwards. The air cylinder has the advantages that the front end cover of the air cylinder has no air hole, and the two gas pipelines are connected on the rear end cover
