6. A bracket device, comprising:

a bracket comprising a longitudinal wall and at least one mounting member mounted adjacent to the longitudinal wall;

an engaging member comprising a connecting portion and a resilient arm, the connecting portion being connected to the longitudinal wall of the bracket, the resilient arm being extended from the connecting portion, the resilient arm having a first engaging feature;

a fastening member displaceable with respect to the bracket, and the fastening member comprising a side wall, a fastening portion bent with respect to the side wall, a second engaging feature formed on the side wall and an elongated hole formed on the side wall;

a resilient member; and

an operating member having a fixing portion and an operating portion, the fixing portion being connected to the longitudinal wall of the bracket via a fixing member passing through the elongated hole, the operating portion being flexibly connected to the fixing portion, and the operating portion corresponding to the resilient arm of the engaging member;

wherein when the fastening member displaces with respect to the bracket from a first position to a second position, the fastening portion is moved closer to the at least one mounting member, and the first engaging feature is engaged with the second engaging feature, such that the fastening member is kept at the second position with respect to the bracket, and the resilient member maintains a resilient force;

wherein when the first engaging feature is disengaged from the second engaging feature, the fastening member recovers to the first position from the second position with respect to the bracket in response to the resilient force released from the resilient member, such that the fastening portion is moved farther away from the at least one mounting member.

7. The bracket device of claim 6 , wherein the bracket further comprises an end wall substantially perpendicularly connected to the longitudinal wall, and the at least one mounting member is mounted on the end wall.

8. The bracket device of claim 6 , wherein the fastening portion of the fastening member is substantially perpendicularly connected to the side wall.

9. The bracket device of claim 6 , wherein the longitudinal wall of the bracket comprises a first constraining feature, the side wall of the fastening member comprises a second constraining feature, and the first constraining feature cooperates with the second constraining feature.

10. The bracket device of claim 6 , wherein the longitudinal wall of the bracket is connected to a slide rail.

11. A bracket device adapted to mount a slide rail to a post with a plurality of holes formed thereon, the bracket device comprising:

a bracket comprising a longitudinal wall and a mounting member mounted adjacent to the longitudinal wall, the longitudinal wall configured to be connected to the slide rail, and the mounting member for being mounted to one of the holes of the post;

an engaging member comprising a connecting portion and a resilient arm, the connecting portion being connected to the longitudinal wall of the bracket, the resilient arm being extended from the connecting portion, the resilient arm having a first engaging feature;

a fastening member longitudinally displaceable with respect to the bracket, and the fastening member comprising a side wall, a fastening portion bent with respect to the side wall, a second engaging feature formed on the side wall and an elongated hole formed on the side wall;

a resilient member for providing resilient force to the bracket and the fastening member; and

an operating member having a fixing portion and an operating portion, the fixing portion being connected to the longitudinal wall of the bracket via a fixing member passing through the elongated hole, the operating portion being flexibly connected to the fixing portion, the operating portion having a contacting feature passing through the elongated hole, the contacting feature corresponding to the resilient arm of the engaging member;

wherein when the fastening member displaces with respect to the bracket from a first position to a second position, the fastening portion is configured to be moved closer to the post for locking the post, and the first engaging feature is engaged with the second engaging feature, such that the fastening member is kept at the second position with respect to the bracket, and the resilient member maintains a resilient force;

wherein the resilient force is for recovering the fastening member to the first position, such that the fastening portion is configured to be moved farther away from the post for unlocking the post.
