The sliding direction of 105 loads or exits the second rail 105.

In use, the connection line of the server chassis 200 is wound around the first support arm 10 The first bobbin 12 and the second bobbin 22 of the second support arm 20 are correspondingly engaged in the clamps 14, 24 that are snapped thereon. When the server cabinet 200 is pushed into the cabinet 100, the connecting member 30 is bent, and the angle between the first bobbin 12 and the second bobbin 22 becomes smaller and close to each other, and the first rail 103 is The rear end extends between the second bent portion 527 of the bracket 52 and the second rail 105 and abuts against the second bent portion 527 (shown in FIG. 2). When the connection line of the server chassis 200 is large, the first winding bar 12 and the first rail 103 are subjected to a large force, and the second bending portion 527 of the bracket 52 of the second mounting component 50 is attached. The first rail 103 can effectively prevent the first rail 103 from being deformed inwardly and damaged. When the server chassis 200 is withdrawn, the first mounting assembly 40 slides forward with the first rail 103, the connecting member 30 gradually straightens, and between the first winding bar 12 and the second winding bar 22 The angles are increased and separated from each other.

When the cable management device is detached from the rail device 101 of the cabinet 100, the operation portion 442 of the fastener 44 of the first mounting assembly 40 is pulled away from the bracket 42 to make the first rail 103 convex. The head portion 1044a of the plug 104a is disengaged from the fixing hole 446 of the fastener 44, and the bracket 42 is pulled backward. The neck portion 1042a of the bolt 104a slides into the guiding portion from the fixing portion 4244 of the mounting hole 424 of the bracket 42. 4242. At the same time, the neck portion 1042b of the bolt 104b slides out of the mounting opening 426 of the bracket 42 to pull the bracket 42 away from the first rail 103. The head 1044a of the bolt 104a is from the bracket. The guiding portion 4242 of the mounting hole 424 of the 42 is passed out, and the first mounting assembly 40 can be detached from the first rail 103. When the operating portion 442 of the fastener 44 is pulled, the fastener 44 is not excessively deformed and damaged due to the blocking of the blocking piece 429 of the bracket 42 of the first mounting assembly 40. .

The operating portion 542 of the fastener 54 of the second mounting assembly 50 is pulled away from the bracket 52, so that the card 544 of the fastener 54 is disengaged from the fixing hole 106 of the second rail 105, and the bracket is pulled backward.
