The first buckle groove 21 can accommodate the first buckle 91 inside the plastic part 9.

[0038] Similarly, to avoid interference with the second and third snaps 92 and 93 on the plastic part 9, a second snap groove 5 is formed between two adjacent transverse positioning portions 2 on the same side. The second snap groove 5 can accommodate the second snap 92 inside the plastic part 9. Third snap grooves 6 are formed between the longitudinal positioning portion 4 and the transverse positioning portions 2 on both sides.
