The invention discloses a novel buffer type forklift two-section full-freedom oil cylinder. The novel buffer type forklift two-section full-freedom oil cylinder comprises a cylinder barrel, wherein a guide sleeve and a cylinder bottom are respectively arranged at the two ends of the cylinder barrel; a plunger rod is arranged in the cylinder barrel; a plunger is arranged at the lower end of the plunger rod; a steel backing bearing is arranged on a matched surface of the guide sleeve and the plunger rod; a buffer sleeve is arranged in a central through hole of the plunger; the buffer sleeve and the inner wall of the plunger are fixed by virtue of a steel cable baffle ring; a buffer shaft sleeve is arranged in the central hole of the cylinder bottom; one end of the buffer shaft sleeve extends into the central through hole of the buffer sleeve, and a gap is formed between the buffer shaft sleeve and the buffer sleeve; a transverse oil passing hole, a longitudinal oil passing hole and an oil passing slot are formed in the plunger rod; the transverse oil passing hole respectively communicates with the longitudinal oil passing hole and the oil passing slot; the transverse oil passing hole communicates with a rod cavity; and the longitudinal oil passing hole communicates with a rodless cavity. The oil cylinder disclosed by the invention is simple in structure; and gap buffer is firstly applied to the plunger piston type oil cylinder, so that the buffer effect is improved.
