Referring to fig. 7, fig. 7 is a schematic structural diagram of a cable clamp 50 according to an embodiment of the present invention, and in some embodiments, the cable clamp 50 includes a clamp body 52, a flexible layer 54, and a connector 56. The clamp body 52 is provided with an open clamping space 521, the flexible layer 54 extends and is laid on the inner wall of the clamping space 521, and the connecting piece 56 is arranged on the side of the clamp body 52 opposite to the open clamping space 521 and is used for connecting the connecting piece 56 with the inner wall of the purlin 30. Thus, the cable clamp 50 can be fixed inside the purline 30 through the connecting piece 56, and then the cable 300 is clamped into the clamping space 521 formed in the clamp body 52 through the opening, so that the cable 300 can be supported to prevent the cable 300 from contacting rainwater for a long time to cause potential safety hazards.
