[0044] The execution control hydraulic pump 3-1 pumps out the oil and sends it to the execution control reversing valve 6-1, and then by adjusting the working state of the execution control reversing valve 6-1, the execution control reversing valve 6-1 sends the oil to the execution control pipe 10 or the execution control pipe 2 11 to realize the action of the actuator.
