The invention provides a ballastless track portable height adjustment and distance adjustment fastener piece. The ballastless track portable height adjustment and distance adjustment fastener piece comprises a base plate, a hydraulic jack, spiral track nails and distance adjustment bases, the base plate is fixed to the ballastless track ground through the spiral track nails, and the fastener piece is characterized in that two distance adjustment bases which have the same structure and are symmetrically arranged are installed on the base plate, the two ends of two distance adjustment cross shafts are fixedly installed on the distance adjustment bases through bearings, the distance adjustment cross shafts are connected through gears, and distance adjustment screw caps drive the distance adjustment cross shafts to rotate through the gears; support legs of an abutting lifting plate are in threaded connection with the two distance adjustment cross shafts, the lower portion of the abutting lifting plate is in contact with the hydraulic jack, and the hydraulic jack is installed on the base plate between the two distance adjustment cross shafts; the track is put on the abutting lifting plate and is fixed through elastic strip fastener pieces. According to the ballastless track portable height adjustment and distance adjustment fastener piece, the height of the track is adjusted by the hydraulic jack, the displacement of the track in the horizontal direction is controlled through the rotation of the two distance adjustment cross shafts, and the ballastless track portable height adjustment and distance adjustment fastener piece is easy to operate and high in automated degree, and can save a lot of manpower.
