Fastener For Ornament With Pin

A fastener for an ornament having a pin which includes a housing that has a pin passing hole for insertion of the pin included in the ornament and an opening portion that is provided at a position directly opposite to the pin passing hole,

• a pin retaining portion which is disposed inside the housing to clamp and retain a pin inserted through the pin passing hole between the respective spherical surfaces of a plurality of small balls,
• a control lever which is installed consecutively at the pin retaining portion via a column portion outside the opening portion and releases the pin which has been clamped and retained outside the housing by pulling backward the pin retaining portion from the pin passing hole, and
• a coil spring which is disposed on an outer periphery of the column portion inside the housing and urges the pin retaining portion and the control lever in a direction of the pin passing hole, and
• the fastener for an ornament having a pin which is arranged so that
• the pin is clamped and retained by the small balls of the pin retaining portion in such a manner that the pin retaining portion is urged to the pin passing hole side, by which each of the small balls is pushed in a pin direction and a part of the spherical surface of each of the small balls on the pin side is brought into contact with the pin in a pressed state, and
• a motion of releasing the pin which has been clamped and retained by the pin retaining portion is performed by pulling backward the pin retaining portion from the pin passing hole to release a pressing force to the pin by each of the small balls, wherein
• the column portion is provided with an outer column portion of a cylindrical body which is formed integrally with the pin retaining portion in a direction at which the pin retaining portion is pulled backward and also has internally a through hole in the same direction as a direction at which the pin is inserted and
• an inner column portion of a cylindrical body which is inserted and fixed on the through hole inside the outer column portion, formed integrally with the control lever in a direction at which the control lever is urged and has a through hole acting as a passage for introducing the pin inserted through the pin passing hole.
