Novel oil-gas lubrication connecting device

The utility model belongs to the technical field of cold-roll steel sheet online production equipment, and particularly relates to a novel oil-gas lubrication connecting device which comprises a base, four fixing rods are fixedly connected to the left side of the base, moving rods are connected to the fixing rods in a sliding mode, the same damping plate is welded to the ends of the four moving rods, and the damping plate is connected with the base. A groove is formed in the base, a lead screw is rotationally connected between the inner walls of the two sides of the groove, and the end of the lead screw extends out of the base and is provided with a rotary knob in a welded mode. The rotary knob is rotated to drive the moving plate to move through the lead screw, the moving plate drives the adjusting plate to move through the hinge rod, the adjusting plate compresses the buffer spring, the compression stroke of the adjusting plate is shortened, and therefore the elastic force of the buffer spring in the compre
