A pedestal assembly (20) includes a chassis (200), a gear wheel (300) pivotably mounted to the chassis, two supporting members (400) coupled to the chassis, and a coil spring (500) received between the chassis and the gear wheel. The chassis includes a stop portion (222) depending downwardly from a side of a top wall (210) thereof. The gear wheel includes first teeth (330) extending from a periphery thereof. Each supporting member includes a rack (440) comprises second teeth (444) engaging with the first teeth, and a first clasping portion (448) formed on an outer side thereof. When one of the first clasping portions is locked by the stop portion, the coil spring is compressed, while when the first clasping portion is unlocked from the stop portion, the coil spring is decompressed and drives the gear wheel to rotate to cause the supporting members to move relative to the gear wheel.

The pedestal assembly as described in claim 5, wherein a second cylinder extends upwardly from the disk, the first cylinder and the second cylinder are coaxial, the first teeth extend outwardly from a periphery of the second cylinder. 7. The pedestal assembly as described in claim 1, wherein each of the supporting members further comprises a main body, and the base depending from an end of the main body, the rack extends from the other end of the main body. 8. The pedestal assembly as described in claim 7, wherein a clasping portion extends from the other end of the main body of each of the supporting members, and is parallel to the corresponding rack. 9. The pedestal assembly as described in claim 8, wherein another clasping portion is formed on an outer side of the rack of each of the supporting members, and the second teeth are formed on an inner side of the rack or each of the supporting members, said clasping portion and said another clasping portion of each of the supporting members cooperatively prevent the corresponding supporting member from disengaging disengaging from the chassis. 10. A pedestal assembly for supporting a computer enclosure, the pedestal assembly comprising: a chassis mounted to a bottom plate of the computer enclosure, the chassis comprising a top wall underlying the bottom plate of the computer enclosure, the top wall comprising a stop portion depending from a side thereof; a gear wheel pivotably mounted to the chassis, the gear wheel comprising a plurality of first teeth extending outwardly from a periphery thereof; a coil spring received between the gear wheel and the chassis; a pair of supporting members coupled to the chassis, each of the supporting members comprising a rack, and a base cooperative with the chassis supported on a plane to support the computer enclosure thereon, the rack comprising a plurality of second teeth engaging with the first teeth of the gear wheel and a first clasping portion being lockable with the stop portion directly; wherein when the first clasping portion of one of the supporting members is locked with the stop portion of the chassis, the coil spring is compressed and the bases of the supporting members are in respective first positions, while when the first clasping portion is unlocked from the stop portion, the coil spring is decompressed and drives the gear wheel to rotate to cause the supporting members to move with the bases of the supporting members moving away from the chassis to respective second positions where the bases extend to outside of the bottom plate of the computer enclosure and the first clasping portion is locked with the chassis and unlockable with the stop portion. 11. The pedestal assembly as described in claim 10, wherein the chassis comprises a pair of sidewalls depending from opposite sides of the top wall, a pair of bottom walls each interconnecting opposite bottom end of the sidewalls, and an opening bounded by the sidewalls, the bottom walls and the top wall, the opening for receiving the gear wheel and the supporting members. 12. The pedestal assembly as described in claim 11, wherein each of the sidewalls define a cutout adjacent to a, corresponding bottom wall, and the stop portion protrudes from one of the cutouts, a handle portion extends outwardly from the stop portion. 13. The pedestal assembly as described in claim 11, wherein a first locating portion protrudes from a bottom surface of the top wall, a second locating portion protrudes from a bottom surface of the gear wheel, the coil spring abuts against the first and second locating portions. 14. The pedestal assembly as described in claim 10, wherein a pivot axis protrudes from a bottom surface of the top wall. 15.
