The hanging rod 03 is positioned and connected to the hanging pipe 02 by a thread, so that the hanging and fixing height of the cable rack 01 can be adjusted accordingly according to the communication engineering site environment and actual cabling needs. The structure is flexible and highly adaptable.

[0019] Example 2: The wiring board 10 of this utility model is divided into a left wiring board 101 and a right wiring board 102. The left wiring board 101 is connected to the right wiring board 102. The left wiring board 101 has retaining strips 17 on both sides, and the right wiring board 102 has retaining grooves 16 on both sides. The retaining strips 17 are adapted to the retaining grooves 16 and are connected to the retaining grooves 16.
