[0020] like Figure 3 As shown, the positioning component 15 includes a first sleeve 501 connected to the upper end of the connecting sleeve 1, and a limiting pillar 506 is movably installed in the first sleeve 501. Tenon grooves 507 are provided at the upper and lower ends of the limiting pillar 506. A first installation port 502 and a second installation port 504 are provided on the side wall of the first sleeve 501. A first tenon 503 is provided in the first installation port 502. A first limiting ring 505 is provided at the first installation port 502 on the first sleeve 501. A movable groove is provided in the first sleeve 501. The limiting pillar 506 is movably installed in the first sleeve 501 through the movable groove. The first tenon 503 is connected to the upper end of the limiting pillar 506 through the tenon groove 507. The limiting pillar 506 is limited in the first sleeve 501 through the first tenon 503, and the first tenon 503 is limited in the first installation port 502 through the first sleeve 501.

[0021] Specifically, the first sleeve 501 can be connected to the upper end of the connecting sleeve 1 through the upper thread 3, and the first tenon 503 can be connected to the first mounting port 502 and the second mounting port 504. When the first tenon 503 is connected to the first mounting port 502, the limiting pillar 506 is received in the first sleeve 501. When the first tenon 503 is connected to the second mounting port 504, a part of the limiting pillar 506 will extend out of the first sleeve 501.

[0022] like Figure 4 As shown, the positioning component 2 6 includes a second sleeve 601 connected to the lower end of the connecting sleeve 1, a docking groove 602 is provided at the upper end of the second sleeve 601, a third installation opening 604 is provided on the side wall of the second sleeve 601, a second tenon 603 is provided in the third installation opening 604, and a second limiting ring 605 is provided at the third installation opening 604 on the second sleeve 601, and threads are provided in the first limiting ring 505 and the second limiting ring 605, the first limiting ring 505 and the second limiting ring 605 are respectively connected to the first sleeve 501 and the second sleeve 601 by threads, the limiting pillar 506 is connected to the second sleeve 601 through the docking groove 602, the second tenon 603 is limited in the third installation opening 604 by the second limiting ring 605, and the limiting pillar 506 is limited in the docking groove 602 by the second tenon 603.
