A first bevel gear 84 is fixedly connected to the outside of the screw rod 81. A second bevel gear 85 is meshed with the outside of the first bevel gear 84. A knob 86 is fixedly connected to the bottom of the second bevel gear 85. The knob 86 is rotatably connected to the fixed rod 5 through a bearing. By designing the knob 86, the knob 86 can drive the second bevel gear 85 to rotate. Both the first bevel gear 84 and the second bevel gear 85 are rotatably connected to the fixed rod 5. By designing the adjusting mechanism 8, it is convenient to adjust the position of the cable isolation support.

[0024] Please refer to Figure 1 , Figure 2 , Figure 4 , the rotating mechanism 9 includes a groove 91. A groove 91 is formed inside the rotating seat 3. A ball 92 is movably sleeved inside the groove 91. The number of grooves 91 is multiple. The multiple grooves 91 are annularly and continuously and evenly distributed inside the rotating seat 3. By designing the multiple grooves 91, the ball 92 can roll into the grooves 91 at different positions. The ball 92 is movably connected to the support column 2.
