A multi-sample, multi-layer positioning device according to an embodiment of the present utility model is described below in conjunction with fig. 1-4. Fig. 1 illustrates a schematic perspective view of a multi-sample, multi-layer positioning device according to an embodiment of the present utility model, and as shown in fig. 1, the multi-sample, multi-layer positioning device according to an embodiment of the present utility model includes a plurality of sample fixing assemblies 100 and a support assembly 200. The sample fixing assembly 100 includes a sample holder 120, and a plurality of fixing members 110 are disposed on the sample holder 120 at intervals, and the fixing members 110 are used for fixing a sample. The plurality of sample fixing members 100 are sequentially stacked on the support member 200 in the up-down direction.

According to the multi-sample and multi-layer positioning device provided by the embodiment of the utility model, the samples are fixed on the sample placing rack 120 through the fixing piece 110, so that the samples are placed more conveniently, and the placing positions of the samples are also more accurate.
