It is further explained that in addition to the above-mentioned embodiments, the center line of the second through hole 14 can also not overlap the center line of the interval between the two first through holes 13, but it is necessary to ensure that the projection area of the interval corresponds to the part of the second through hole 14, and the arrangement mode of the third through hole 15 is similar to that of the second through hole 14. It should be noted that the above examples of N=2 and N=3 are given, and the number can be adjusted according to the requirements in practice, and the number is not limited here.

The first fixing sheet 31 is hooked in the fixing hole 16, that is, the first fixing sheet 31 extends into the fixing hole 16 and is bent inward to contact the wall surface of the insertion hole 11, so as to realize the connection of the sleeve body 3 and the conductive body 1. Specifically, the number of fixing holes 16 is two, and the two fixing holes 16 are oppositely distributed. Among them, the sleeve body 3 is provided with two first fixing sheets 31 in each fixing hole 16 for fixation, so as to improve the fixation effect.
