Performance detection die body for dental cone-beam X-ray tomography equipment

The utility model discloses a dental cone-beam X-ray tomography equipment performance detection die body, the detection die body is cylindrical, the detection die body is formed by stacking a plurality of layers of single bodies, and the single bodies comprise effective single bodies and surface single bodies; the detection die body comprises two layers of surface layer monomers and at least one layer of effective monomers, and the effective monomers are clamped between the two layers of surface layer monomers; a plurality of sets of fixing holes corresponding in position are formed in the edges of the single bodies, and a plurality of fixing columns penetrate through the single bodies of all the layers from the fixing holes respectively and lock the single bodies of all the layers. Matched positioning mechanisms are further formed on the single bodies and distributed on the surfaces of the single bodies on the adjacent layers. The device is convenient to use and low in comprehensive cost, can be freely combi
