MAGNETIC ATTRACTION-FIXING ASSEMBLY, TWO-PIECE APPARATUS, AND ROTATING SUPPORT STRUCTURE FOR A PORTABLE DEVICE HAVING THE MAGNETIC ATTRACTION-FIXING ASSEMBLY

摘要

A magnetic attraction-fixing assembly and a rotating support structure for a portable device are provided. The magnetic attraction-fixing assembly includes two magnetic units, the two magnetic units stacked with and attracting each other; wherein each of the magnetic units respectively comprises a circular magnetic component and at least one annular magnetic component around the circular magnetic component, a magnetic pole of the circular plane of the circular magnetic component is an unlike pole to a magnetic pole of an annular plane of the annular magnetic component that is adjacent to the circular magnetic component. The rotating support structure comprises two magnetic units and a body. Magnetic attractions in both radial and axial directions are enhanced.
