Abstract: A fixing device comprises a bracket. The bracket comprises a positioning block. The positioning block comprises a positioning post. The bracket defines an opening and a receiving space. The opening communicates with the receiving space. A storage device extends into the receiving space from the opening. The positioning block is configured to resiliently move back. The positioning post is configured to be received in a fixing hole of the storage device to engage with storage device.

Abstract: A positioning apparatus includes a computer chassis and a positioning device. The computer chassis secures a plurality of expansion cards and includes a cover. The cover comprises a first flange and a second flange opposite to the first flange. The positioning device includes a securing member and a positioning member secured to the securing member. The securing member is secured to the first flange and a second flange. The positioning member is pressed on the plurality of expansion cards to prevent the plurality of expansion cards from moving.

Abstract: A single mounting apparatus for securing a number of expansion cards includes a resisting member rotatably attached to the chassis and a clamping buckle. The clamping buckle includes a pressing piece, a supporting portion, an operating portion, and a catching member. A securing space is defined in the resisting member for latching the catching member. When the catching member is caught in the securing space, the securing member is clamped between a flange of the chassis and the resisting member to stop the rotation of the resisting member. The pressing piece presses down on and secures the expansion cards. Lifting the clamping buckle upwards unlatches the catching member from the securing space and causes re-rotation of the resisting member to allow dismounting of the expansion cards.

Abstract: An exemplary computer case includes a side plate, a rear cover and a knob. The side plate defines a recess. The rear cover defines a flange for abutting against the side plate when the side plate is attached to the computer case. The knob is partially and rotatably received in the recess. The knob includes a protruding member capable of being driven to rotate to a position where the protruding member and the side plate cooperatively sandwich the flange therebetween so that the side plate is attached to the computer case.

Abstract: An electronic apparatus includes a first drive bracket and a second drive bracket. The first drive bracket includes a bottom plate. The bottom plate defines a receiving groove and an arc-shaped sliding groove. The second drive bracket includes a top wall. The top wall includes a knob and at least one sliding member formed thereon. The knob is received in the receiving groove to work as an axis. The at least one sliding member is received in the sliding groove, and capable of sliding in the sliding groove to a mounted position. In the mounted position, the top wall of the second drive bracket is aligned with the bottom plate of the first drive bracket.
