Abstract: A combined heat-dissipating structure includes a main heat-dissipating structure and a detachable heat-dissipating structure. The main heat-dissipating structure has an opening, on which the detachable heat-dissipating structure is detachably disposed. A heat conduction column of the main heat-dissipating structure and a heat conduction column of the detachable heat-dissipating structure can be thermally coupled with different heat sources respectively. An electronic apparatus casing includes a casing base and the above combined heat-dissipating structure. The combined heat-dissipating structure and the casing base are connected to form an accommodating space. The combined heat-dissipating structure can dissipate heat from heat sources accommodated in the accommodating space. An electronic apparatus includes two heat sources and the above electronic apparatus casing. The two heat sources are accommodated in the accommodating space.

Abstract: The disclosure provides an adjustable fixing assembly. The adjustable fixing assembly includes a base plate and a cover plate. The cover plate includes a plate portion and a protrusion portion protruding from the plate portion. The cover plate includes a first installation position and a second installation position. When the cover plate is in the first installation position, the protrusion portion extends away from the base plate, and the cover plate is spaced apart from the base plate by a first minimum distance. When the cover plate is in the second installation position, the protrusion portion extends towards the base plate, and the cover plate is spaced apart from the base plate by a second minimum distance, where the second minimum distance is smaller than the first minimum distance.

Abstract: A mounting bracket is configured to accommodate a memory card or a hard disk. The mounting bracket includes a base plate, two side plates, a plurality of protruding bumps and at least two supporting structures. The side plates are respectively connected to two opposite edges of the base plate, and extend along a direction perpendicular to the base plate. The protruding bumps are disposed on the base plate and protrude towards the direction. The supporting structures are located between the side plates and respectively disposed on the side plates. When the mounting bracket accommodates the memory card, the protruding bumps are configured to support the memory card. When the mounting bracket accommodates the hard disk, the supporting structures are configured to support the hard disk.

Abstract: A host with a removable device includes a main body, a removable device, and a fixing and withdrawing mechanism. Each element of the fixing and withdrawing mechanism is connected with each other by using a plurality of springs. When the removable device is placed into the host, a slide rod is pushed and a link rod is linked, such that the removable device is fastened in the host by using the link rod. When a user pulls an actuating rod, the link rod is guided to release the fastening state, and the removable device is ejected by using the slide rod under the forces of the springs.
