Abstract: A snap coupling cooling fan module is adopted for use on a computer system to provide the heat dissipation apparatus required by the computer system. The cooling fan module includes a fan lid, which has one side pivotally engaged with a frame and another side latched on a board extending from the frame by means of a latch hook so that a space is formed to house the fans. Matching anchor stubs and latch stubs are formed to clamp and anchor the fans without screws. Installation and disassembly may thus be done faster to save assembly and repair costs.

Abstract: A disk reading device operates in both a suction mode and a cover-lifting mode. The device has a lower cover having a wall with an elongated opening provided in the wall, an upper cover that is connected for pivoting movement with respect to the lower cover, and a disk receiving space between the lower and upper covers. The disk receiving space is accessible via the elongated opening in a suction mode and by opening the upper cover with respect to the lower cover in a cover-lifting mode. A disk is drawn via the elongated opening into the disk receiving space, or a disk can be manually placed in the disk receiving space by opening the upper cover with respect to the lower cover. The device also includes a switch that switches operation of the disk reading device from the suction mode to the cover-lifting mode.

Abstract: A reed-type clamp device. The reed-type clamp device comprises a main body, a rotating ring, a reed and a clamp. The rotating ring has a ring portion and a lever portion. The ring portion has a plurality of protrusions formed on the inner circumference of the ring portion. The rotating ring is disposed on the main body and rotates clockwise and counterclockwise. A plurality of swing arms are extended from the outer edge of the reed. The swing arm has an outer end fixed on the main body and a driving portion. The protrusions of the rotating ring touch the driving portions. The clamp is fitted in the reed. By rotating the rotating ring, the swing arms of the reed fixed on the main body are pushed upward or downward such that the clamp can be moved upward or downward.
