Beschreibung
Zusammenfassung:	The invention provides a protective device of a hydraulic oil cylinder. The protective device of the hydraulic oil cylinder comprises a base, an inner circle and an elastic component, wherein the inner circle is arranged in an inner ring of the base, the inner circle is provided with an oil through hole, one end of the elastic component is arranged on the inner ring of the base, the other end of the elastic component is raised towards the direction away from the inner circle, and a part of the oil through hole is shielded when the elastic component deforms and is attached to the inner circle. Damage to related equipment and parts caused by flow and pressure jump of an oil pipe is avoided.
