Abstract: The fixing structure of the invention capable of connecting to a pen with a slot comprises a main body, a slide piece, and a push module. The main body comprises a slide slot and an opening. The slide piece can slide into the slide slot. The slide piece comprises a first slide unit and a second slide unit. The first slide unit comprises a first pressing element. The push module comprises a second pressing element, and the push module has a loose state and a tight state. When the push module is in the loose state, at least a portion of the first pressing element is in the opening; when the push module is in the tight state, the second pressing element connects to the second slide unit, and the first pressing element connects to the slot of the pen.

Abstract: A hinge assembly for pivotably connecting the display portion and the body portion of the portable computer comprises a first fastening portion for attaching to the display portion, a second fastening portion for attaching to the body portion and a pivot portion for pivotably connecting the first fastening portion with the second fastening portion. The second fastening portion also has a first support arm for horizontally inserting into the insertion hole. The cables, for transmitting signals and power extending from the display portion, are electrically connected through connectors to the cable connection region. The cable connect region is formed on the rear wall or bottom wall of the body portion. The hinge assembly of the invention greatly reduces the extraordinary sound resulting from the rotation of the display portion. Also, some covering components can be eliminated to make the assembly much easier.
