Abstract
A fastening structure includes a circular sleeve and a coupling member. One end of the circular sleeve has a receiving trough. A bottom of the receiving trough is provided with a first magnetic member. A wall of the receiving trough is provided with a protruding post. At least one guide groove is formed on an outer wall of one end of the coupling member. One end of the guide groove is an open axial groove having an opening. Another end of the guide groove is a closed axial groove having a stop end. The guide groove has a transverse groove between the open axial groove and the closed axial groove. Another end of the coupling member is a pivot end that has a central passage extending inwardly. A second magnetic member is disposed in the central passage. The first and second magnetic members have repulsive magnetic poles.
