Special tool and method for remaking horizontal measuring point

The invention discloses a special tool for remanufacturing a horizontal measuring point, which comprises a measuring bushing and a drill rod, the measuring bushing is a T-shaped rotary body, a through hole is formed in the middle of the measuring bushing, three equal-height three-jaw bosses are uniformly distributed at the bottom of the measuring bushing, the three-jaw bosses are used for positioning on the surface of an airplane, the drill rod is a T-shaped rotary body, the bottom of the T-shaped rotary body is a sharp point, and the bottom of the drill rod is a conical surface. The sharp point is used for marking a horizontal measuring point on the surface of an airplane, the drill rod is installed in a through hole in the middle of the measuring bush, and the sharp point of the drill rod is exposed out of the bottom of the through hole. The method has the advantages that the problem that the airplane horizontal measuring point which is thick in paint layer and high in surface quality requirement is difficu
