The hydraulic oil cylinder with the buffer piston comprises a cylinder body, a cylinder base, a piston rod and a piston device, the piston device comprises the piston, a valve sleeve unit and a one-way valve unit, the one-way valve unit is installed in the valve sleeve unit, and the valve sleeve unit is installed in an installation groove axially formed in one end of the piston rod. The two ends of the one-way valve unit are inserted into the two ends of the valve sleeve unit respectively, one end of the one-way valve unit penetrates through one end of the valve sleeve unit and penetrates through a first insertion hole formed in the piston rod in the axial direction, and the end portion of one end of the one-way valve unit abuts against a plug pin arranged on the piston rod in the radial direction. The other end of the one-way valve unit penetrates through the other end of the valve sleeve unit and penetrates through a second insertion hole formed in the axial direction of the piston, and the end part of the
