Accessory for electronic device

An accessory for an electronic device, comprising:

• a cone, which has an empty space therein, a wrinkle part formed on a body thereof so as to be folded in a telescopic manner, and an upper portion and a lower portion, which are open;
• an inverted cone, which has an empty space therein, a wrinkle part formed on a body thereof so as to be folded in a telescopic manner, an upper portion that is open, and a lower portion having a protrusion extending therefrom, the protrusion having a screw hole formed in the center of the bottom surface thereof;
• a ring plate having a diameter larger than that of an upper opening of the cone and added to the bottom surface of the protrusion while the protrusion is inserted into the upper opening of the cone;
• a screw for fixing the ring plate to a hollow center portion of the protrusion;
• a neck cylinder, which surrounds the neck part of the protrusion and is in direct contact with a narrow upper portion of the cone and a narrow lower portion of the inverted cone as forcibly separating the two cones and forms and maintains a gap between them;
• and
• a first cover for covering a lower opening of the cone,
• wherein the first cover includes:
• a mounting disc, which has a plurality of locking blades provided at regular intervals along the circumference of the mounting disc, and has a lower surface to be attached to a portable electronic device;
• and
• a main disc, which has a diameter corresponding to the diameter of the lower opening of the cone and has a receiving part formed on a lower surface thereof so as to accommodate the mounting disc, and
• wherein if the mounting disc is rotated in place while the mounting disk is inserted into the receiving part, the mounting disc and the main disc are fastened to each other by the plurality of locking blades.
