Patent ID: 8534777

Claim:
A supporting device for fixing an electronic element on a computer housing, the supporting device comprising: a loading device for loading the electronic element, the loading device comprising a rectangular first sidewall and a bottom wall connected to the first sidewall, the first sidewall having an outer surface and an inner surface, the first sidewall defining a curved first sliding slot, a straight second sliding slot extending along a width direction of the first sidewall, and a fixing hole adjacent to the bottom wall, wherein all of the first sliding slot, the second sliding slot, and the fixing hole pass through the outer surface and the inner surface; and a first locking device positioned on the first sidewall, the first locking device comprising: a connecting pole slidably positioned on the outer surface along a length direction of the first sidewall, and defining a third sliding slot; a swing pole attached on the inner surface of the first sidewall and having a swing end and a hinge end opposite to the swing end, the swing end defining a first through hole, the hinge end defining a second through hole; a buckle attached on the swing pole and defining a third through hole; a first bolt extending through the third through hole, the first through hole, the first sliding slot, and the third sliding slot; a second bolt extending through the second sliding slot, and having a first resisting portion and a second resisting portion opposite to the first resisting portion, the first resisting portion extending out of the outer surface, the second resisting portion extending in the loading device; and a shaft extending through the second through hole and the fixing hole; wherein when the connecting pole is pushed, the connecting pole drives the first bolt to slide along the first sliding slot until the buckle resists against the upper portion of the second resisting portion, the connecting pole resists against lower portion of the first resisting portion, then the connecting pole drives the second bolt to slide along the second sliding slot in a direction away from the bottom wall, the second bolt pushes the buckle to move until the buckle is coupled with the computer housing, and thus the supporting device is locked with the computer housing.
