At this time, the straight plate 906 is in a vertical state. When the rotating shaft 905 rotates, it can drive the rotating plate 904 to rotate synchronously to a vertical state. The operator rotates the third bolt 903 so that one end of the third bolt 903 can be pressed against the surface of the transition valve body 1, so that the straight plate 906 The angle of 06 is fixed so that the support plate 902 can stably fit the connection between the oil pipe 7 and the transition valve body 1, reducing the probability of disconnection due to impact. After completing the above operations, oil is supplied so that the hydraulic oil can enter the interior of the transition valve block 1. After adjusting the oil supply through the servo valve 4, transmission and other operations can be performed. The internal pressure is detected by two pressure sensors provided inside the transition valve block 1, and the pressure value is transmitted to the computer in real time.
