Localization guidance device for continuous pore-forming or groove-forming of down-the-hole drill

The invention discloses a localization guidance device for continuous pore-forming or groove-forming of a down-the-hole drill. The device comprises a guiding mechanism and a positioning mechanism, wherein the guiding mechanism comprises a base, a guiding groove and two installation grooves which are arranged in parallel and in the same length are formed in the length direction of the base, the two installation grooves are symmetrical about the center line of the guiding groove, and scale marks are arranged in the length direction of the base; the positioning mechanism comprises a positioning plate, a positioning hole and two rows of parallel connecting holes are formed in the positioning plate, the connecting holes are symmetrical about the center line of the positioning hole, the diameter of the positioning hole is slightly larger than the diameter of the down-the-hole drill and smaller than the width of the guiding groove, the vertical distance between the circle center of the positioning hole and the line
