3. The fixing apparatus as claimed in claim 1 , wherein the latches of the first side plate and the second side plate each comprise a hook formed at a distal end thereof, detachably locking with each other.

4. The fixing apparatus as claimed in claim 1 , wherein the first side plate and the second side plate each comprise a platform extending from an outside thereof.

5. The fixing apparatus as claimed in claim 4 , wherein a pair of operating arms extends oppositely from ends of the platform, respectively near the latches.

6. The fixing apparatus as claimed in claim 5 , wherein a pair of wedged block extends from outsides of the platforms near the operating arms, respectively.

7. The fixing apparatus as claimed in claim 4 , further comprising a pair of shock absorbing bars, wherein each of the first side plate and the second side plate comprises a retaining groove defined in an inside thereof, corresponding to the corresponding platform, for receiving the shock absorbing bar therein.

8. The fixing apparatus as claimed in claim 7 , wherein each of the shock absorbing bars comprises a plurality of mounting portions formed therein, the first and second side plates each comprises a plurality of mounting holes defined therein to receive the mounting portions of the shock absorbing bar.

9. The fixing apparatus as claimed in claim 8 , wherein a plurality of fixing holes is defined in the shock absorbing bars to receive the fixing pins therein.

10. A HDD assembly slidably received in a rack, the HDD assembly comprising:

a HDD defining a plurality of holes in opposite sidewalls of the HDD; and

a fixing apparatus receiving the HDD, the fixing apparatus comprising:

a first side plate attached to one of the opposite sidewalls of the HDD, and comprising a pivoting portion and a latch at opposite ends thereof;

a bracket attached to the other sidewalls of the HDD, pivotably connected to the pivoting portion of the first side plate about a pivoting axis extending in a first direction, and comprising a latch detachably locking with the latch of the first side plate;

a pair of shock absorbing bars respectively attached to the first side plate and the bracket, and abutting against the opposite sidewalls of the HDD; and

a plurality of fixing pins extending from the shock absorbing bars in a second direction substantially perpendicular to the first direction, and inserted into the holes of the HDD.

11. The assembly as claimed in claim 10 , wherein the bracket comprises a second side plate, and an end plate perpendicularly extending from the second side plate, a free end of the end plate pivotably engages with the pivoting portion of the first side plate, the latch extends from a free end of the second side plate, the latches of the first side plate and the second side plate move toward or far away from each other in response to the end plate pivoting relative to the first side plate.

12. The assembly as claimed in claim 11 , wherein each of the latches of the first side plate and the second side plate comprises a hook formed at a distal end thereof, detachably locking with each other.

13. The assembly as claimed in claim 11 , wherein each of the first side plate and the second side plate defines a lengthwise retaining groove, the shock absorbing bars are elongated and respectively retained in the grooves of the first side plate and the second side plate.

14. The assembly as claimed in claim 13 , wherein each of the shock absorbing bars comprises a plurality of mounting portions formed therein, each of the first and second side plates defines a plurality of mounting holes communicating with the retaining grooves of respective first and second side plates, the mounting portions are received in the mounting holes of the first and second side plates.

15. The assembly as claimed in claim 11 , wherein the rack defines a pair of railways in opposite side walls, each of the first side plate and the second side plate forms a lengthwise platform protruding from an outside thereof and slidably received in the railways of the rack, respectively.

16. The assembly as claimed in claim 15 , wherein a pair of operating arms extends oppositely from ends of the platforms near the latches, respectively.

17. The assembly as claimed in claim 16 , wherein a pair of wedged blocks extends from outsides of the platforms near the operating arms, respectively.
