Summary:The invention belongs to the technical field of sampling devices, and provides a breast tumor sampling device which comprises a sampling barrel, a negative pressure assembly, a cutting assembly and a moving assembly. The sampling barrel is held, the through hole in the cutting barrel makes contact with the surface of a tumor, then negative pressure is generated in the second mounting cavity through the negative pressure assembly, and at the moment, the negative pressure generated in the second mounting cavity can suck one part of the tumor into the cutting barrel from the through hole; then the cutting assembly is pressed to enable the cutting blade to move horizontally to cut off the tumor in the through hole, the cut tumor specimen is located in the cutting cylinder, and then the moving assembly is rotated to drive the tumor specimen in the cutting cylinder to move, so that the obtained tumor specimen is separated from the through hole; and the tumor can be sampled again by repeating the steps, so that repe
