Point fixing device convenient for detecting concrete strength by rebound method

The utility model belongs to the technical field of auxiliary detection, and particularly relates to a point fixing device convenient for detecting concrete strength by a rebound method. The technology comprises a frame, a plurality of first dividing strips and second dividing strips are arranged in the frame, the first dividing strips and the second dividing strips divide the interior of the frame into a plurality of areas with the same size, a plurality of fixing blocks are evenly fixed to the edge of the frame, and through holes communicated front and back are formed in the fixing blocks. Fixing columns are independently arranged in the through holes, one ends of the fixing columns are provided with adhesion assemblies used for adhering the fixing columns to the concrete wall face, and the other ends of the fixing columns are provided with limiting assemblies used for preventing the fixing blocks from being disengaged. According to the design, the fixing blocks are hung on the concrete vertical wall face t
