A server includes a tray, a handle structure, a first hard disk assembly and a second hard disk assembly. The tray is removably disposed on a server cabinet. Two ends of the handle structure are respectively slidably pivoted to two inner walls of the tray. The first hard disk assembly is movably disposed in the tray. The second hard disk assembly is disposed in the tray. The first hard disk assembly and the second hard disk assembly are placed side by side. Two sides of the first hard disk assembly, which are opposite to each other, are pivoted to the handle structure. When the handle structure is pivoted and slide relative to the tray, the first hard disk assembly is pivotable between a stored position and an inclined position by the handle structure.

The present application provides an SSD card adapter bracket and a circuit board assembly. The SSD card adapter bracket includes a bracket member, a first screw, a conductive bouncing sheet, and a second screw. The bracket member includes a card base part and an extension part, and one side of the card base part is provided with a screw base. One side of the extension part is connected to the card base part, and the other side of the extension part is provided with a connection part. The first screw is threadedly connected to the screw base, and can press the SSD card to the screw base. The conductive bouncing sheet has a first end part and a second end part, the first end part is sandwiched between the first screw and the screw base, and the second end part corresponds to the connection part.

A lifting module for a chassis and an electronic device including the lifting module are provided. The lifting module includes a sidewall bracket, a lifting bracket, a sliding button assembly, and a driven assembly. The sidewall bracket is disposed on a side frame of the chassis. The lifting bracket is movably connected to the sidewall bracket. The sliding button assembly is slidably disposed on the side frame of the chassis. Part of the sliding button assembly is exposed from the chassis. The driven assembly is movably disposed on the sidewall bracket. The driven assembly is connected to interact the sliding button assembly and the lifting bracket. The lifting bracket is driven to move relative to the sidewall bracket selectively by the sliding button assembly through the driven assembly.
