After scanning a bolt hole, the lifting module 404 drives the bolt hole scanning rotating mechanism 3 to move upwards to the highest position, the positioning mechanism 2 three-jaw chuck 206 at the rear end of the carrier vehicle body 1 contracts, so that the positioning mechanism 2 at the rear end is separated from the wall of the bolt hole, and is lifted to the highest position by the positioning lifting mechanism 202, and is meshed with the vehicle body transmission gear 104 through the positioning driving gear 204, so that the positioning mechanism 2 at the rear end is transmitted to the next bolt hole, at the moment, the positioning mechanism 2 at the front end of the carrier vehicle body 1 is kept fixed in the bolt hole, and the carrier vehicle body 1 is also kept fixed; after the positioning mechanism 2 at the rear end is driven to the next screw hole, the positioning lifting mechanism 202 drives the three-jaw chuck to descend into the next screw hole wall again, and the three-jaw chuck expands again and is fixed with the screw hole wall. At this time, the front and rear positioning mechanisms 2 of the carrier vehicle body 1 are located at the same moving side and fixed to the screw hole wall, and at this time, the two positioning driving gears 204 rotate in the same direction at the same time, so that the carrier vehicle body 1 can be driven to drive the bolt hole scanning lifting mechanism 4 and the bolt hole scanning rotating mechanism 3 to move to the next screw hole, and the three-dimensional scanning work of the screw hole can be performed.
