Rock core splitting machine for geological exploration

The invention discloses a rock core sample splitting machine for geological exploration, relates to the technical field of geological mineral exploration, and solves the problems that a rock core is easy to splash in a sample splitting process and the personal safety of workers is difficult to guarantee because no fixing device for fixing the rock core exists at present; sample splitting cannot be carried out according to rock cores with different lengths, and certain limitation exists in the using and operating process. Comprising an operation table, a guide plate is fixedly installed in the operation table, two moving plates are connected to the surface of the guide plate in an interactive mode, fixing assemblies are arranged on one sides of the two moving plates, a lead screw is rotationally connected into the operation table, and the screwing directions of threads at the two ends of the lead screw are opposite; the device has the advantages that the two ends of a rock core can be conveniently fixed, the s
