The invention relates to a universal coupling mechanism for rotating guide drilling tools. The universal coupling mechanism comprises a plurality of drill rods, cross sleeves and fastening blocks. Cylinders are arranged at the ends of the drill rods in a protruding way, and notches matched with the cylinders are arranged at the ends of the cross sleeves. The ends of the drill rods are sleeved in the cross sleeves, and the cylinders arranged at the ends of the drill rods are inserted into the notched disposed at the ends of the cross sleeves. The fastening blocks are fixedly connected at the edges of the cross sleeves corresponding to the notches, and the plurality of drill rods are connected in sequence in a sleeved mode through the cross sleeves. The universal coupling mechanism can increase deflecting force and make the deflecting rate to achieve a practical effect; meanwhile simplifies the underground control system, reduces cost and control difficulty of the underground control system, and improves the working ability of the underground control system.
