Patent ID: 8444233

Claim:
An electronic device comprising: a chassis with an opening defined therein, the opening having a first side edge and a second side edge located at opposite sides of the opening, and a length of the second side edge being greater than that of the first side edge; and a bracket, mounted in the opening, comprising a pair of first hooks and a pair of second hooks; the pair of first hooks are located at a first side of the bracket, and the pair of second hooks are located at a second side of the bracket that is opposite to the first side; a first distance between the pair of first hooks corresponding to the length of the first side edge; and a second distance between the pair of second hooks corresponding to the length of the second side edge; wherein the pair of first hooks is engaged with the first side edge of the opening, and the pair of second hooks is engaged with the second side edge of the opening; the bracket further comprises a first side wall, a second side wall opposite to the first side wall, a pair of first resilient arms extending from the first side wall, and a pair of second resilient arms extending from the second side wall; the pair of first resilient arms lay substantially in the same plane as the first side wall, and the pair of second resilient arms lay substantially in the same plane as the second side wall; the pair of first hooks is protruded towards the first side edge from distal ends of the pair of first resilient arms; and the pair of second hooks is protruded towards the second side edge from distal ends of the pair of second resilient arms; a third distance between the first side wall and the second side wall is substantially equal to a fourth distance between the first side edge and the second side edge; a pair of protruding pieces protrudes from two corners of the opening at the first side edge, and the pair of first resilient arms is located between the pair of protruding pieces and abuts the pair of protruding pieces; the pair of second resilient arms abuts an upper edge and a lower edge of the opening; a pair of block pieces protrudes from the upper and the lower edges of the opening, and the bracket abuts the pair of block pieces.
