ABSTRACT:
A key ring holder comprising a hanger loop secured to two symmetrical passage ways on a circular groove around the peripheral wall of a flat, circular base thereof by a metal bolt, a compression spring and a washer is disclosed. The compression spring and the washer are sleeved on the metal bolt and stopped between a contracted hole at one end of a stepped through hole inside the flat, circular base and an expanded bottom end of the metal bolt. The hanger loop is constantly pulled downwards by the compression spring and the metal bolt to block up the two symmetrical passage ways. Pulling the hanger loop upwards from the flat, circular base and rotating it sideways causes the two symmetrical passage ways to be opened for fastening key rings to the circular, flat base.
