A second guide structure 44 is provided on the positioning plate 4, and a second guide groove is provided on the sheath shell 1. The second guide structure 44 is slidably matched with the second guide groove; the second guide structure 44 and the second hook 41 are arranged in the same direction. The cooperation between the second guide structure 44 and the second guide groove guides the installation of the positioning plate 4, facilitating the rapid installation of the positioning plate 4 on the sheath shell 1.
[0034] Furthermore, the first pin 2 and the second pin 3 are inserted into the sheath housing 1, and both the first pin 2 and the second pin 3 are provided with a barb structure.
