Zusammenfassung:	The utility model provides a double-hydraulic-cylinder structure. A double-hydraulic-cylinder structure comprises an oil way control system, a first hydraulic cylinder and a second hydraulic cylinder,the first hydraulic cylinder and the second hydraulic cylinder are connected with the oil way control system, and the first hydraulic cylinder comprises a cylinder barrel, a piston rod and a piston.Wherein a rodless first cavity, a rod second cavity and a third cavity are formed in the piston rod, the size of the cavity changes along with the extending length of the piston rod, the first cavity,the second cavity and the third cavity are not communicated with one another, and the second hydraulic cylinder comprises a rodless fourth cavity and a rod fifth cavity; and the third cavity is communicated with the fourth cavity or the fifth cavity through an oil path control system. The two hydraulic cylinders are in linkage and are matched with the oil way control system, so that the first hydraulic cylinder can drive t
