Cutting structure and cutting device with same

The invention relates to a cutting structure and a cutting device provided with the same. The cutting structure is arranged on an upper die holder and is characterized by being provided with at least one group of first annular cutting edge and second annular cutting edge which are arranged at intervals in the first direction, the first annular cutting edges surround the first central axis and can rotate with the first central axis as a rotation axis, the second annular cutting edges surround the second central axis and can rotate with the second central axis as a rotation axis. According to the cutting structure, the tangent theorem of a circle (the tangent of the circle is perpendicular to the radius passing through the tangent point of the circle) is utilized, so that the vertical cutting effect is achieved at each stress position and any angle, and therefore burrs on a cut surface are reduced, the quality of the cut surface is improved, and the whole cutting structure has high durability. 本发明涉及一种切割结构及设有其的切
