The piston structure comprises an oil inlet pipe, an oil outlet pipe and a piston which comprises an oil cylinder and a pushing rod. The pushing rod moves in a reciprocating mode in the oil cylinder. The pushing rod divides the oil cylinder into a first oil chamber and a second oil chamber. The first oil chamber is provided with a first oil opening. The second oil chamber is provided with a second oil opening. An electro-hydraulic directional valve is further arranged. A first port and a second port are arranged on one side of the electro-hydraulic directional valve. A third port and a fourth port are arranged on the other side of the electro-hydraulic directional valve. The first oil opening is connected with the first port through an oil pipe. The second oil opening is connected with the second port through an oil pipe. One end of the oil inlet pipe is connected with the third end opening. One end of the oil outlet pipe is connected with the fourth end opening.
