Hydraulic oil cylinder with high buffering performance

The utility model discloses a hydraulic oil cylinder with high buffering performance. The hydraulic oil cylinder comprises a cylinder body, a heat dissipation structure is arranged outside the cylinder body, a piston rod is installed on one side in the cylinder body, a piston body is installed on one side of the piston rod, a sealing assembly is installed outside the piston body, and buffering structures are arranged on the two sides of the piston body. By arranging the buffering structure, when the piston body moves to the leftmost position in the cylinder body, the buffering plate on the left side can be attached to the left side in the cylinder body and is extruded to drive the buffering spring to contract, and in the contracting process, a certain buffering effect can be achieved between the cylinder body and the piston body; and when the piston body moves to the rightmost side in the cylinder body, a buffer plate on the right side can be driven to be attached to the right side in the cylinder body, then
