The oil cylinder with the locking structure comprises a cylinder body, a piston and a plug rod, a cavity is formed in the cylinder body, the piston is movably arranged in the cavity, one end of the plug rod is fixedly connected with the piston, the other end of the plug rod penetrates through the cylinder body, and a liquid inlet and a liquid outlet are formed in the two ends of the side wall of the cylinder body respectively. And a locking device is in threaded connection with the interior of the liquid inlet. The oil conveying pipeline is simple in structure, convenient to use and high in safety performance, the pressure on one side of the spring is reduced when the oil conveying pipeline leaks in the heavy object supporting process of the oil cylinder through the arranged locking device, the spring returns to the original position to drive the movable block to abut against the surface of the limiting ring block, and under the pressure effect of hydraulic oil in the oil cylinder, themovable block is driven
