Transfer device for placing three-dimensional atom probe sample

A transfer device for placing a three-dimensional atom probe sample comprises a base, a handle and a plurality of first bolts, the handle is fixedly arranged at the top end of the base, a plurality of containing holes for placing the sample are formed in the base, a plurality of first threaded holes are formed in the side face of the base, and the first threaded holes correspond to the containing holes one to one. The first threaded holes are threaded through holes, the tail ends of the first threaded holes communicate with the interior of the containing hole, and the multiple first bolts are screwed into the multiple first threaded holes correspondingly. The sample transfer device can be used for simultaneously placing a plurality of samples, is simple to operate, convenient and stable to fix the samples, not easy to damage the samples during transfer, high in inclusiveness to the sizes, the shapes and the surface smoothness of the samples and convenient to use, and belongs to the technical field of sample t
