The present invention offers a fixing structure for input keys, applied in personal digital assistant provided with function of a mobile telephone. On the backside of the case of a framework are provided a plurality of positioning elements and a plurality of thermomeltable elements respectively. On said positioning elements and thermomeltable elements are sheathed consecutively with elastic sheet, plate, circuit board and fixing plate. Each end of said thermomeltable elements is accommodated in corresponding recessed hole provided in said fixing plate to avoid interference with other parts. Pressing keys set up on elastic sheet can be just protruded from the case respectively, and by means of a bottom plate kept flat against the whole bottom, the fixing structure is completed. In this way, not only is the aim to decrease thickness of PDA achieved, but also it is convenient for users to carry.

A removable cover assembly is to be assembled to the main body member of the electronic product. The main body member includes an upper housing and a lower housing. The lower housing has a groove of the rotation axis and at least one groove of the leading rail and the upper housing has a groove of the affixing buckling hook. The removable cover assembly includes a cover member and an affixing pushing cover, wherein the cover member includes a cover and a rotation axis that is affixed to both sides of the cover. The affixing pushing cover includes an affixing buckling hook and at least one leading rail, wherein the leading rail is located at the back side of the affixed pushing cover, and is with respect to the position of the groove of the leading rail. The affixing buckling hook is located on a side of the affixing pushing cover and is with respect to a position of a groove of the affixing buckling hook. During assembly, the rotation axis on the cover is engaged in tabling to the groove of the rotation axis, so that the cover member and the lower housing are in combination. In addition, the leading rail on the affixing pushing cover can slide along the groove of the leading rail until the affixing buckling hook and the groove of the affixing buckling hook are buckled up. The present invention can allow the user to promptly detach or attach the cover, according to the user's actual need.
