Beschreibung
Zusammenfassung:	The invention relates to an oil cylinder with two auxiliary oil supply channels. The oil cylinder mainly comprises a main oil cylinder and an inner oil cylinder in a piston rod of the main oil cylinder, wherein an auxiliary oil supply port 1 at the front end of the piston rod of the main oil cylinder is communicated with a rod cavity of the inner oil cylinder through an oil hole in the piston rod of the main oil cylinder; the rod cavity of the inner oil cylinder is communicated with an auxiliary oil supply channel hole 1 at the bottom of a cylinder barrel of the main oil cylinder through a communicating oil hole 1 in a piston rod of the inner oil cylinder; an auxiliary oil supply port 2 at the outer end of a plug is communicated with a rodless cavity of the inner oil cylinder through an oil hole in the plug of a cylinder bottom of the inner oil cylinder; and the rodless cavity of the inner oil cylinder is communicated with an auxiliary oil supply channel hole 2 at the bottom of the cylinder barrel of the main
