Abstract: A fastening structure for an expansion card is provided. The card has a baffle and one end of the baffle is formed with a bending portion and a first long hole. The fastening structure includes a flat plate located at one side of a case and has a plane extending toward inside the case; a first supporting portion and a second supporting portion fastened at the plane of the flat plate; a fastening member having a pressing portion and at least one second long hole. The fastening member is disposed at the first supporting portion via the second long hole, and slidably leans against the plane. The pressing portion extends toward the bending portion. When the fastening member slides to a fixing position, the pressing portion presses the bending portion, and the baffle is fastened at the second supporting portion via the first long hole and leans against the plane.

Abstract: The present invention provides a casing structure formed with a base and a covering, wherein the base is formed with a first lateral supporting, a second lateral supporting corresponding to the first lateral supporting, a third lateral supporting formed with a first coupling portion and coupled to the first lateral supporting and the second lateral supporting, and a second coupling portion corresponding to the third side; and the covering is formed with a first side coupled to the first lateral supporting, a second side corresponding to the first side and coupled to the second lateral supporting, a third side formed with a third coupling portion and coupled to the first side and the second side, and a fourth coupling portion coupled to the second coupling portion and corresponding to the third side. The base is firmly coupled to the covering so as to prevent electromagnetic waves from escaping.

Abstract: A disk drive fixing device for carrying and fixing a disk drive on a mounting surface, includes a main body for carrying at least one disk drive; and a buffer disposed on one side of the main body, for being indirectly fixed to the mounting surface. The buffer completely covers a fixing portion of the main body, wherein the fixing portion is for being fixed to the mounting surface, and the buffer can be fixed to the mounting surface by a fixer, such that the fixing portion of the main body can be indirectly in contact with the fixer and the mounting surface via the buffer, thereby providing an anti-shock effect for the disk drive indirectly fixed on the mounting surface.

Abstract: A fastening device for a heat sink, for being combined to each of two sides of a base of the heat sink for fastening the heat sink on an installing face is disclosed, wherein the two sides of the base respectively include jointing holes. The fastening device has at least a body, a positioning portion provided at the bottom of the body and a spiral fastening portion provided on the body to be combined with the base via spiral fastening components. Since the heat sink can be fastened via two of the fastening devices in conjunction with the spiral fastening components, problems in the prior art, such as complicated structure, excessive amount of components used and extra usage space required, can be solved.
