Diaphragm splitting machine slip shaft and splitting machine

The invention aims at disclosing a slip shaft of a diaphragm splitting machine and the splitting machine. The slip shaft comprises a core shaft and a plurality of magnetic driving assemblies arranged in the axial direction of the core shaft. The magnetic driving assembly comprises a gear outer ring, a backstop inner ring, a fixed inner ring and a bearing, the backstop inner ring comprises a horizontal surrounding part and a vertical backstop part, the fixed inner ring is provided with an annular cavity, and an aluminum ring, a plurality of magnets, a magnet fixing ring and a magnet adsorption ring are sequentially arranged in the annular cavity; the magnet fixing ring is provided with a plurality of hollow parts, and the hollow parts are arranged corresponding to the magnets; the magnetic drive gear has the technical effects that a plurality of magnets of the magnetic drive assembly are driven by the mandrel to rotate, new magnetic induction lines are formed due to the fact that eddy current is generated when
