The connecting pipe 4 is made of plastic, such as PE, PP, etc. that can deform to some extent. One end of the connecting pipe 4 is provided with a limiting ring 5 extending towards the direction of the circle center, and the other end of the connecting pipe 4 is provided with a locking pipe 6 used for fixing the cable 10. The locking pipe 6 is communicated with the connecting pipe 4, the locking pipe 6 is made of aluminum alloy, and the connecting pipe 4 and the locking pipe 6 are fixedly connected together by strong glue to form a whole. The cable 10 is inserted into the locking tube 6 and inserted into the connecting tube 4, and the cable 10 is fixed by the locking tube 6 so that the cable 10 is fixed in the connecting tube 4. The specific fixing manner of the cable 10 is as follows:

the locking pipe 6 is provided with three threaded holes 7 along the radial direction, and the threaded holes 7 are uniformly distributed along the circumferential direction of the locking pipe 6.
