Zusammenfassung:	The utility model discloses a drilling machine limiting frame for slope support drilling. The drilling machine limiting frame comprises a triangular limiting frame body used for limiting the angle ofa drilling machine and a supporting limiting frame body used for limiting the angle of the triangular limiting frame body. The supporting limiting frame comprises a horizontal supporting rod, a vertical telescopic supporting rod and two laser transmitters symmetrically arranged at the two ends of the horizontal supporting rod. The triangular limiting frame comprises a right-angled connecting rod and a limiting inclined rod arranged on one side of the right-angled connecting rod; the right-angled connecting rod comprises a vertical connecting rod and a horizontal connecting rod which are connected with the horizontal supporting rod; and a plurality of inclined rod angle adjusting bolts are arranged on the vertical connecting rod. The drilling machine is simple in structure, reasonable in design, high in practicabil
