Abstract: A key structure is provided. The key structure includes a switch and a keycap. The switch includes a stem. The keycap is located over the switch. The keycap includes a pressing surface, an inner bottom surface and a protrusion post. The pressing surface and the inner bottom surface are opposed to each other. The protrusion post is protruded downwardly from the inner bottom surface. The protrusion post includes an insertion groove and at least one exhaust recess. When the stem is tightly fitted into the insertion groove, a gap is formed between the at least one exhaust recess and the stem.

Abstract: A mouse device includes a casing, a top cover, an adjusting module and a pressing part. The casing is covered by the top cover. The top cover is movable relative to the casing. The top cover includes a saw-toothed plate. The saw-toothed plate is inserted into an inner portion of the casing and contacted with the adjusting module. The pressing part is connected with the adjusting module. When the pressing part is pressed to trigger the adjusting module, the saw-toothed plate is pushed by the adjusting module and the top cover is moved form a first position to a second position. Consequently, a shape of the mouse device is changed. The shape of the mouse device is changeable according to the size of the user's palm.

Abstract: A fastening device includes a base and a fastening member. The base defines a receiving space for receiving an electronic component. The fastening member includes a fastening portion and an elastic abutting portion. The fastening portion is fixed to the base. The elastic abutting portion extends from the fastening portion upwards and through the base and is configured for securing the electronic component in the receiving space.

Abstract: An electrical adapter assembly for connecting a first hard disk drive and a second hard disk drive is provided. The electrical adapter assembly includes a connector capable of electrically inserting into the first hard disk drive, a printed circuit board (PCB) module electrically connecting the connector, and a loading member for loading the first hard disk drive. The PCB module includes a chip for controlling data transfer between the first hard disk drive and the second hard disk drive. The loading member includes a base and at least two guiding portions pivotally attached on the base to allow the first hard disk drive to be able to slide between the at least two guiding portions.

Abstract: An improved structure for portable electronic device is presented using elastic material for building guide rails for support, protecting a mini storage device inside the portable device, and permitting the consumer, while using the portable electronic device, to protect the mini storage device from shock damage. The portable electronic device contains a casing. The casing further contains a containing space. The containing space connects to the exterior via an opening. The parallel side walls of the containing space, which also include a pair of guide rails, are perpendicular to the exterior. The guide rails are made of an elastic material. The mini storage device passes through the above opening, enters the casing, moves along the guide rails, and finally is placed inside the containing space.
