[0009] The utility model uses a large number of cables in information engineering for equipment connection and signal transmission. The distribution frame organizes and supports the cables of the information engineering and clamps them in a limited position through the clamping plate to avoid entanglement and knotting of multiple cables, which is convenient for later maintenance and sorting of the cables. The cables are placed on the inner side of the clamping plate, and the relative distance between the clamping plates on both sides is changed by driving the displacement of the single-side clamping plate, so that cables of different diameters can be clamped. The utility model has a flexible structure and a wide range of applications. At the same time, by increasing the cable fixing fulcrum, the stability of the cable connection is improved to prevent the cable connection from loosening, which affects the connection of information engineering equipment and signal transmission.

[0010] The position-controlling support rod of the utility model increases the connection fulcrum between the fixed wiring frame and the movable wiring frame, and the position-controlling support rod is positioned and connected with the position-controlling support block through a thread, so that when the position-controlling support rod is driven to rotate by turning the knob, the position-controlling support block drives the movable wiring frame to perform lateral linear displacement, thereby changing the relative distance between the clamping plates on both sides.

[0014] The utility model has a plurality of positioning lock grooves evenly distributed on the axial direction of the control support rod, and the positioning lock groove cooperates with the positioning lock rod to brake and control the position of the control support rod. When the pull ring is pulled up until the positioning lock rod and the positioning lock groove are completely disengaged, the spring bar is compressed by force, and the positioning fulcrum of the control support rod for the fixed wiring frame disappears. At this time, according to the actual use requirements of the wiring frame, the movable wiring frame can be driven to move laterally by turning the knob to facilitate the insertion, removal and clamping of the cables. When the pulling force on the pull ring disappears, the movable pressure plate is pushed by the elastic tension of the spring bar itself and automatically resets to the position lock rod embedded in the positioning lock groove, thereby increasing the positioning fulcrum of the fixed wiring frame for the control support rod. At this time, the control support rod is braked and locked and cannot be rotated, thereby ensuring the stability of the clamping force of the clamping plates on the cables on both sides. The structure is flexible and the operation is convenient.
[0015] The utility model arranges and supports the cables to avoid entanglement and knotting of multiple cables, which is convenient for the later maintenance and sorting of the cables.
