Patent attributes
A portable storage device comprises a protecting housing, a casing, a keystroke, a circuit board, and an electrical plug. There is an orientating hole which comprises the first fixing portion formed on the protecting housing. The casing slides in the interior of the protecting housing, and comprises a flexible arm which corresponds in position to the orientating hole. The keystroke is positioned between the flexible arm and the orientating hole, and fixed with the orientating hole when the second fixing portion formed on the keystroke is latched with the first fixing portion. Such that the electrical plug connected with the circuit board mounted in the casing can be moved selectively in or out of the protecting housing through the keystroke. Thereby, it is convenient for a user to protect the electrical plug of the portable storage device, and the reliability of the device can be improved automatically.
