The conductor spacers in the existing technology have a fixed format and cannot be effectively used to fix conductors of different numbers and arrangements. Their applicability is poor, so it needs to be improved. Summary of the Invention

[0006] By adopting the above technical solution, a corresponding number of rods are selected based on the number and placement format of the wires. By pulling the pins, the rods can be rotated relative to the center disk, thereby adjusting the rods to the position of the wires, and then fixing the wires with the fixators, thereby achieving the splitting effect of wires of different numbers and distribution forms, and improving the overall applicability.

[0007] Preferably, the cross-section of each of the rods is fan-shaped, a plug-in strip is provided on one side wall of the rod, and a plug-in slot for inserting the plug-in strip of another rod is provided on the other side wall of the rod.

[0008] By adopting the above technical solution, the cross-section of the rod body is set to be fan-shaped, which makes it convenient to place the rod bodies in a centralized manner when the spacer rods of this application are not in use, reduce gaps, save space, and set plug-in strips and plug-in slots to improve the stability of the connection between the rod bodies.

[0009] Preferably, a magnetic element is provided in the plug-in slot, and the magnetic element is magnetically attracted to the plug-in strip.

When the length needs to be adjusted, pull the locking plate, the waist-shaped groove will be disengaged from the clamping ring groove, and the adjusting rod will enter the adjusting groove, and then you can pull the mounting block to achieve length adjustment. When the adjustment is completed, just loosen the locking plate, and the waist-shaped groove can be clamped into the corresponding clamping ring groove to fix the core.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Based on the number and placement of wires, select the corresponding number of rods. By pulling the latch, the rods can be rotated relative to the center disk, thereby adjusting the rods to the wire position.
