The control mechanism 2 is fixedly arranged on the box 1 and electrically connected with the electromagnetic valve to control the on-off of the electromagnetic valve and the flow rate of the hydraulic oil. The test mechanism 3 is arranged in the cavity of the box 1, and the test mechanism 3 is connected with the electromagnetic valve through the hydraulic oil pipe. When the hydraulic oil enters the test mechanism 3, the pressure of the hydraulic oil flowing through the test mechanism 3 is monitored in real time to ensure that the hydraulic oil controls the extension and retraction of the throttle control stick in a constant pressure state.
