The inner side of the arc groove is attached with a rubber layer 7. The separator 2 can divide the cable trough 1 into a plurality of areas for accommodating a plurality of cables 4, thereby improving the fixing efficiency of a plurality of cables 4 at the same time. The rubber layer 7 can avoid direct contact between the cable 4 and the upper seat 5 or the lower seat 6, thereby reducing wear and tear and preventing leakage through the rubber layer 7.

[0031] To further optimize the solution, Figure 3 , 4 As shown, both ends of the upper seat 5 are mounting ends, the top surface of the mounting end is provided with a first pin hole 8, and both ends of the lower seat 6 are provided with second pin holes 9, and the pin connectors are respectively plugged into the first pin hole 8 and the second pin hole 9; the two sides of the bottom surface of the upper seat 5 are respectively fixedly connected with driving blocks 10, and the two ends of the top surface of the lower seat 6 are respectively provided with snap-in grooves 11, and the driving block 10 is slidably connected with the snap-in groove 11; one end of the pre-tightening component passes through the side wall of the snap-in groove 11, and the first pin hole 8 and the second pin hole 9 are connected together by the pin connector, thereby realizing the detachable connection between the upper seat 5 and the lower seat 6.
