Low-loss detection sampling device for internal defects of building stand column

The invention discloses a building stand column internal defect low-loss detection sampling device, and belongs to the field of building engineering detection.The building stand column internal defect low-loss detection sampling device comprises a fixing disc, the fixing disc is fixedly installed, the output end of a driving motor penetrates through the fixing disc to be fixedly connected with a drill rod, and fixing blocks used for clamping a building stand column are arranged at the bottoms of four supporting columns in a sliding and penetrating mode; an annular groove is formed in the inner wall of the drill rod, and a cutting mechanism used for cutting the building stand column is arranged in the annular groove. Through the arrangement of the driving motor, the drill rod and the cutting mechanism, the driving motor drives the drill rod to isolate sampling points of the building stand column, the cutting mechanism cuts off the sampling points, part of the sampling points in the building stand column can be
