The utility model discloses a buffering type hydraulic oil cylinder which comprises a base, a cylinder body is fixedly installed on the top of the base, a rubber seat is fixedly installed on the bottom side in the cylinder body, and a movable plate is movably connected in the cylinder body. A first oil outlet pipe and a second oil outlet pipe are fixedly installed on one side of the cylinder body and located above and below the movable plate correspondingly. The first spring, the rubber seat and the rubber ring are matched with one another, preliminary buffering is carried out through the rubber seat, buffering is further carried out again through friction force between the sliding rod and the rubber ring, the first spring can be extruded in the moving process of the sliding rod, and the sliding rod is prevented from moving. When the first spring resets, the borne force can be converted into elastic potential energy to be released, the sliding rod can drive the transverse plate to extrude the second spring in
