The lower frame is welded by steel plates and steel sections. By turning the locking nut, the lower frame is fixed on the boring machine bed with a locking block. Loosening the locking nut allows the lower frame to be longitudinally adjusted on the boring machine bed. The middle frame is welded by steel plates and is a set of frames of different heights. According to the height of the boring position, appropriate selection is made, and a small horizontal distance adjustment can be made on the horizontal platform. The upper frame is composed of a welding and assembly structure.
