A cable management device comprising:

• a first cable management arm;
• a second cable management arm;
• a cable management seat pivotably connected between the first and second cable management arms;
• an extension board fixed to the cable management seat;
• a support seat having a support board;
• a first connection element connected to the first cable management arm;
• a second connection element connected to the second cable management arm;
• a third connection element connected to the support seat;
• a first support member having a first connecting end and a first free end which is located corresponding to the first connecting end, the first support member pivotably connected to the support seat by the first connecting end, the first support member contacting the support board of the support seat;
• a second support member having a second connecting end and a second free end which is located corresponding to the second connecting end, the second support member slidably connected to the first support member so as to extend relative to the first support member to move the second free end away from the first support member, the second free end having a guide member which is extended therefrom and located between the first and second cable management arms;
• a first resilient member connected between the first and second support members so as to provide a pull force to the second support member;
• and
• a slide pivotably connected to the extension board and slidably connected to the second support member;
• wherein, the first cable management arm is connected to a stationary first position by the first connection element, the second cable management arm is connected to a changeable second position by the second connection element, the support seat is connected to a stationary third position by the third connection element, when the second connection element of the second cable management arm is moved away from the first connection element of the first cable management arm, the cable management seat slides along the second support member by the slide and moves away from the support seat, the slide contacts the guide member and extends the second support member relative to the first support member so as to swing the first support member relative to the support seat.
