Abstract: An electronic device includes a housing, a first electronic component, a second electronic component, two resilient assemblies, and two rotating levers. The housing defines an accommodating space. The second electronic component is fixed in the accommodating space. Each rotating lever includes a first end and a second end. A distance between the second end and a rotation shaft is less than a distance between the first end and the rotation shaft. A handle is rotationally fixed on the first electronic component. When the first electronic component slides into the accommodating space, the handle is rotated toward the first electronic component, the handle drives the two rotating levers to rotate and resist against the resilient assemblies, and the handle overcomes an elastic force applied by the resilient assemblies onto the rotating levers, so that the first electronic component connects with the second electronic component without gaps.

Abstract: A floating directional support for adjusting a gap between a connecting plate and a joint substrate is provided. The connecting plate is mounted on a substrate. The floating directional support includes a base coupled to the substrate and an insertion member coupled to the connecting plate. The insertion member is movably coupled to the base. The gap between the connecting plate and the substrate is adjusted by moving the insertion member relative to the base.

Abstract: A mounting device includes a mounting box, a tray, and a sliding mechanism. The mounting box includes a bottom plate. The sliding mechanism includes a handle and at least one driving member. The driving member is movably coupled to the handle. In a pull configuration of the sliding mechanism, when the handle is rotated toward the bottom plate, the driving member is driven to drive the tray to move along a first direction, and when the handle is rotated away from the bottom plate, the tray is not driven to move. In a push configuration of the sliding mechanism, when the handle is rotated toward the bottom plate, the tray is not driven to move, and when the handle is rotated away from the bottom plate, the driving member is driven to drive the tray to move toward a second direction opposite to the first direction.

Abstract: A self-heating or cooling tube container, which comprises a heat generating or absorbing device. The device includes: a tube provided with a tube head, in which a storage cup is extended out of an upper end of the tube head; a first component and a second component for exothermic or endothermic reaction are respectively accommodated into an inner cavity of the tube and the storage cup sealed with a plug. The container further comprises an outer tube with a screw-on cap that inner have a convex ring and lower edge have a safety belt; when the safety belt is torn off and the outer tube is locked by the cap, the first component and the second component make contact with each other to produce an exothermic or endothermic reaction, and the liquid content in the outer tube can be heated or cooled. The container is applicable to pack medicines or cosmetics.
