An intelligent network patch field management system and specialized cross-connect cable are provided to help guide, monitor, and report on the process of connecting and disconnecting patch cords plugs in a cross-connect patching environment. The sliding block has two second extensions formed on a bottom of the sliding block to correspond to two holes in the base of the blender. Each of the mark elements is made of a second material different from the first material of the first material layer and the mark elements evenly distribute in the mark region. The uneven structure may be unfolded in the longitudinal direction and put in close contact with the first fastening member to achieve firm engagement over an area as large as possible between the flattened uneven structure and the first fastening member. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve. When the legs are rotated to be in the unfolded state, the legs cooperate with the support element to support an electronic device, and when the legs are rotated to be in the folded state, the main body sleeves on the support element receiving the legs.
