Abstract: The present invention is to provide an electronic device including an adjustable angle support and a display device; wherein the adjustable angle support has a top side concavely provided with a supporting portion, and a plurality of recesses provided on the surface of the supporting portion; and the display device has a bottom side configured for pressing against the supporting portion, so as for the display device to be supported and erected on the top side of the adjustable angle support, and a plurality of protrusions provided on the surface of the bottom side of the display device and corresponding in configuration to the recesses respectively. Thus, the angle at which the display device is supported on the adjustable angle support can be adjusted by engagement between the protrusions and the recesses, allowing easy adjustment of the display device to the desired supporting angle as well as easy assembly.

Abstract: A fastening unit includes a hole-defining unit and a fastening component. The hole-defining unit is adapted to be provided in a surface of a first body, and includes a non-circular fastener hole and at least one first engaging part. The fastening component is adapted to be fixed to a second body, is extendible in an axial direction into the fastener hole, and includes a post body and at least one surrounding member. The post body has a non-circular cross-section along a plane transverse to the axial direction, and is provided with at least one second engaging part equal in number to and having a structure complementing the first engaging part. When the fastening component is pushed into the fastener hole to interconnect the first and second bodies, the first and second engaging parts cooperate so that the fastening component is prevented from rotating in the fastener hole.

Abstract: A fastening unit includes a fastening component and a hole-defining unit. The fastening component is adapted to be fixed to a first body, and includes a cylindrical post body and at least one surrounding member. The post body extends along a post axis. The surrounding member surrounds and is fixed to an outer post surface of the post body, and a portion of lines tangent to points on an outermost perimeter of the surrounding member are at non-90° angles with respect to the post axis. The hole-defining unit is adapted to be provided in a surface of a second body, and defines a fastener hole that fittingly receives the fastening component for interconnecting the first and second bodies.
