The lifting limit bolts 6 at the top and bottom ends position and clamp the movable core plate 5.

[0024] The specific settings and effects of the embodiment will be described below. The bus duct is composed of a bus duct base 2 at the bottom end and bus duct side plates 1 on both sides. A plurality of sub-line grooves 3 are installed in the bus duct. The bus duct is used for efficient transmission of electric energy, can collect electric energy from the transformer and distribute it to each power consumption area, and provides power support for numerous electrical equipment. The sub-line groove 3 is a branch circuit leading out of the bus duct to distribute electric energy to each specific power consumption equipment or smaller power consumption area. The line is installed on the sub-line groove 3, and the circuit is uniformly transmitted and distributed through the bus duct to reach the specific power consumption equipment or smaller power consumption area. The socket 4 needs to be provided at the end of the bus duct to lead out the required line and connect with the outside world. Only a part of the line needs to be led out from the socket 4. First, analyze the position of the cable in the sub-line groove 3, and then move the socket 4 to the height of the corresponding sub-line groove 3. For example, if several lines above need to be led out, first loosen the positioning screw 7, separate the positioning screw 7 from the insertion hole 10 of the movable core plate 5, adjust the socket 4 upward by a certain distance, then loosen the jacking limiting bolts 6 at the top and bottom ends, move the position of the movable core plate 5, so that the insertion hole 10 of the movable core plate 5 is aligned with the positioning screw 7 again. After alignment, the jacking limiting bolts 6 above and below are screwed onto the surface of the movable core plate 5 to fix them. The cable is led into the socket 4 from the sub-line groove 3 above, and after being threaded through the threading groove, the cable that does not need to be plugged is led out from below the socket 4. A new bus duct is installed below the socket 4, and the cables are continuously transmitted from the bus duct. The cable that needs to be plugged is connected with the external circuit through the socket 4. The cable that needs to be plugged and the cable that does not need to be plugged can be separated, and the plugged cable can be flexibly adjusted according to the height. This facilitates the neat and clear leading out of the cable at different positions in the bus duct, improves the planning of the cable, and reduces the time for arranging the line.
