The invention provides a cylinder, and particularly relates to a bidirectional telescopic cylinder. The bidirectional telescopic cylinder comprises a cylinder barrel, a main piston, a main piston rod, an auxiliary piston and an auxiliary piston rod, wherein the main piston is arranged in the cylinder barrel; the external load end of the main piston rod is positioned outside the cylinder barrel; the auxiliary piston is arranged in the cylinder barrel; the external load end of the auxiliary piston rod is positioned outside the cylinder barrel; the friction force between the second end of the cylinder barrel and the auxiliary piston rod is adjustable; an air inlet cavity is formed among the inner wall of the cylinder barrel, the main piston and the auxiliary piston; an air inlet is formed in the cylinder barrel; and the air inlet communicates with the air inlet cavity. The working reliability of the bidirectional telescopic cylinder is greatly improved. 本发明提供了一种气缸，具体涉及一种双向伸缩气缸。本发明双向伸缩气缸包括气缸筒、主活塞、主活塞杆、副活塞、副活塞杆，所述
