At this time, the data of the pressure sensor 622 is sent to the controller through the wire. The controller receives the data and controls the external drive adjustment component at the end of the adjustment rope 624 according to the offset position of the four pressure detection plates 621. The adjustment rope 624 is pulled by the external drive adjustment component to drive the spherical pair 623 to perform fine adjustment.
