Novel compression tool

The invention relates to the technical field of material compression related tests, and provides a novel compression tool which comprises a test rack, an upper compression tool, a lower compression tool and a dial indicator. The upper compression tool comprises a first tool table and a first connecting rod, the lower plane of the first tool table is a sample compression plane, and the upper plane of the first tool table is a deformation detection plane; the lower compression tool comprises a second tool table, a third tool table and a second connecting rod, a spherical concave cavity is formed in the upper surface of the second tool table, the upper plane of the third tool table is a sample placement plane, the lower plane of the third tool table is a spherical convex part, and the spherical convex part is matched with the spherical concave cavity; a measuring rod of the dial indicator contacts with the deformation detection plane. The method has the advantages that the compression deformation of the material
