The invention discloses a steering oil cylinder comprising a cylinder body, a cavity is formed in the cylinder body, a first piston is installed in the cavity, a plurality of annular grooves are formed in the inner wall of the first piston in a slotting mode, a second piston is installed on the right side of the first piston, and piston rods are installed in the first piston and the second piston in a sleeved mode. A first oil suction groove and a second oil suction groove are formed in each piston rod, the extending end of each piston rod is connected and provided with a bent part, the other end of each bent part is fixedly provided with a first installing part in a welded mode, the left end of the cylinder body is fixedly provided with a second installing part in a welded mode, and the upper side and the lower side of the left end face and the right end face of the cylinder body are provided with fixing seats in a welded mode; and an oil injection port is welded to the top of the cylinder body, an oil drainage hole is welded to one side of the bottom of the cylinder body, and an access cover is hinged to the front end face of the cylinder body in a slotting mode. The structure is easy to operate and convenient to maintain, and the stability of the piston rods during movement is effectively improved.
