2. In the invention, when the rotating shaft is influenced by external force, the rotating shaft moves in a trace position in the sleeve, namely when the rotating shaft has a trend of moving upwards in the sleeve or moves upwards, the rotating shaft always rotates, so that the pressure boosting piston in the pressure boosting action cylinder always receives the centrifugal force, and at the moment of moving upwards in the rotating shaft, the pressure boosting piston moves under the inertia action, and because the pulley and the track groove of the pressure guiding ring are provided with an axial connecting structure, the pressure boosting piston in the pressure boosting action cylinder above the rotating shaft stretches and upwards extrudes the corresponding part of the pressure guiding ring, so that the piston rod above the pressure guiding ring can upwards extrude hydraulic oil in the pressure guiding action cylinder through the piston rod, the pressure guiding ring which is upwards extruded can be buffered through the extrusion of the piston rod on the piston rod, and at the same time, the piston rod above the pressure guiding action cylinder can upwards lift the piston rod on the lower position, so that the pressure boosting action cylinder inside the pressure guiding action cylinder generates negative pressure, the rotating shaft which is ascending can be pulled downwards, namely when the rotating shaft is offset in the offset direction, the two pressure guiding cylinders are correspondingly offset, and the pressure guiding rings 12 can realize the corresponding offset action;
