Abstract: A lock mechanism including a main body, a base, a rotating component and a position limiting component is provided. The base is slidably connected to the main body, and the main body is sleeved on the base. The rotating component is pivoted to the main body, and the rotating component is configured to drive the base to slide relative to the main body. The position limiting component is coupled to the rotating component so as to lock the rotating component with one of the main body and the base. A holding structure of an electronic device is also provided.

Abstract: An optical disk drive (ODD) including a shell and a locking module is provided. The shell includes a main body portion and a side portion, and the side portion is connected to the main body portion. A concave space is formed between a side surface of the main body portion and a top surface of the side portion. The locking module is disposed inside the concave space. The ODD is detachably held in a support frame of an electronic device through the locking module. In addition, a locking module is also provided.

Abstract: A securing structure is provided, including a frame, a movable member, a fixed member, a first abutting member, a screwing member. The frame includes a passage. The movable member is slidably disposed in the passage, and includes a threaded portion and a guiding slot. The fixed member is affixed on the frame and extends through the guiding slot. The first abutting member has a first inclined surface and is pivotally connected to the movable member. The screwing member is detachably joined to the threaded portion.

Abstract: An unloading mechanism assembly adapted to unload an optical disk drive from a housing of an electronic device includes a guiding component, a push rod and a driving module. The guiding component is disposed at a side of the optical disk drive along a first direction and has a first position limiting slot extending along a second direction, perpendicular to the first direction. The push rod is disposed in parallel with the guiding component along the first direction. The driving module is coupled between the guiding component and the push rod and includes a driving rod movably disposed through the first position limiting slot along a third direction, respectively perpendicular to the first and the second directions. The push rod is adapted to drive the driving module to pivotally rotate with respect to the guiding component.

Abstract: An electronic module ejecting mechanism includes a frame, a door pivoted to the frame, a rod, a sliding sheet slidably disposed on the door, a swing sheet, and a button connected to the sliding sheet. An electronic module is inserted into an opening of the frame. The rod is slidably disposed in the frame and has groove and bending ends. The swing sheet is pivoted to the sliding sheet and has a latch end for inserting into the groove end when the sliding sheet slides to a lock position. When the latch end is inserted into the groove end and the swing sheet swings to an expanding position with opening of the door, the latch end pulls the groove end to make the bending end push the electronic module to partially protrude from the opening. When the door continues opening outwardly, the latch end is separate from the groove end.

Abstract: A riser card rotating module is disposed adjacent to an expansion slot and includes a guide plate, a fixing plate, a riser card, a first pivot member and a second pivot member. The guide plate has a first guide rail parallel to a plug-unplug direction of the expansion slot and a second guide rail perpendicular to the plug-unplug direction of the expansion slot, wherein the first guide rail and the second guide rail communicate with each other to form a T-shape. The riser card is fixed on the fixing plate and has an electric connector. An end of the first pivot member is fixed on the fixing plate. Another end of the first pivot member is movably disposed on the guide plate. An end of the second pivot member is fixed on the fixing plate. Another end of the second pivot member is movably disposed on the guide plate.
