The utility model provides an azimuthal angle of bore hole generally investigates ware, including scale, pivot, it is wherein articulated through the pivot with the one end of scale according to the one end of chi according to chi, cotton rope, according to the other end of chi and the one end fixed connection of cotton rope, the length of scale is 200 mm, length according to the chi is 100 mm. This technical scheme measures the azimuth angle of all kinds of drillings according to the arctan function, will refer to the direction that the tunnel construction was aimed at to the chi during use,flare -outs the cotton rope and hug closely the drilling rod to show the direction of drilling rod with the cotton rope, again with the scale with according to the chi perpendicular, read cable fetchrope and scale nodical to the pivot apart from X mm, X is the azimuthal angle of bore hole angle with arctan value according to chi length ratio promptly so. Can convert in advance on this basis and with a plurality of angle v
