The external pipeline 1 can be conveniently communicated with the first medium inlet and outlet or the second medium inlet and outlet through the flow guide block 6. Since the axis of the interface on the guide block 6 for communicating with the external pipeline 1 coincides with the hinge axis of the hydraulic cylinder 3, the external pipeline 1 can be ensured not to swing along with the swing of the hydraulic cylinder 3; by setting the guide block 6 as a revolving body, the guide block 6 can not rotate when the hydraulic cylinder 3 swings, so that the external pipeline 1 connected to the guide block 6 is ensured not to rotate; the clearance between the installation groove and the flow guiding block 6 can be effectively sealed by arranging the Gelai ring 8.
