Holder assembly for cellular phones

A holder assembly for cellular phones, comprising:

• a holding button adapted to be attached to one of either a cellular phone or a phone case, said button including:
• a base plate adapted for attaching the holding button to one of either the cellular phone or the phone case;
• and
• a button member connected to the center of said base plate, said button member having a pressing part and a wedge part at its outside edge, with both side surfaces of the wedge part converging into the top end of the wedge part;
• a holder having a clip adapted to be clipped on a belt and configured for receiving and for detachably holding said button therein so as to hold the cellular phone or the phone case on the belt, said holder having a T-shaped opening in a wall thereof;
• a T-shaped snap bolt movably set in the T-shaped opening of the holder and biased by a spring at its back surface, said snap bolt being adapted for selectively holding the button in the holder, said snap bolt including:
• a horizontal part curved at its upper front surface, thus having a radius of curvature suitable for allowing said snap bolt to be selectively retracted into the T-shaped opening when the bolt is pressed by the pressing part of the holding button;
• and
• a wedge part integrated with the bottom center of said horizontal part, with both side surfaces of the wedge part converging into the lower end of the wedge part, said wedge part of the snap bolt being brought into contact with the wedge part of the holding button received in the holder, thus allowing the holding button with the cellular phone or the phone case to be rotatable in either direction.
