  • Patent number: 8270173
    Abstract: An electronic device includes a chassis, a cover on the chassis, a fixing member fixed on the cover and a handling member. A pair of latches are arranged on the chassis and each define a latching hole. The fixing member includes a substrate and a pair of side plates each defining a locking groove. A pair of catches extend upwards from the substrate and each define a locking groove. Cooperatively the locking groove and the latching groove forms a closed groove. The handling member includes a pivot received in the closed groove, and a pair of shafts in the guiding grooves. Firstly, the handling member rotates around the shafts to cause the pivot to engage with the latch, and then rotates into the aperture around the pivot to cause the shafts to move upwards to make the cover moving relative to the chassis to lock with the chassis.
