Abstract: A bracket assembly includes a first bracket and a first lock bracket. The first bracket forms a plurality of first guide slots and a plurality of first locking holes, the first guide slot extends along a mounting direction, and a position of the first locking hole in the mounting direction is gradient; the first lock bracket is connected to the first bracket, and includes a first device connecting piece and a first bracket connecting piece, the first device connecting piece forms at least one first device locking hole thereon, the first bracket connecting piece is bent with respect to the first device connecting piece and forms a plurality of first lock holes. In addition, the disclosure further provides an electronic device including the above-mentioned bracket assembly.

Abstract: A fixing support includes first, second and third fixing units and limiting elements. The first fixing unit has a first slide groove extending in first direction. The second fixing unit includes a second-direction fixing portion and a second-direction sliding portion. The second-direction fixing portion has a second slide groove extending in second direction. The second-direction sliding portion is slidably disposed at the second slide groove. The third fixing unit includes a third-direction fixing portion and a third-direction sliding portion. The third-direction fixing portion has a third slide groove extending in third direction. The third-direction sliding portion is slidably disposed at the third slide groove. The limiting elements allow the first, second and third fixing units to slidably connect to each other and allow the first, second and third directions to be linearly independent of each other. An electronic device is further introduced.
