[0052] In some embodiments, the main body 1 further includes a positioning pin 15 , which is positioned and sequentially passed through the first plate 11 , the sealing connection plate 12 , and the second plate 14 .

[0053] 2-3 , the main body 1 is further provided with a positioning pin 15, and the positioning pin 15 can be set to multiple, and the positioning pin 15 is positioned and passed through the first plate 11, the sealing connecting plate 12 and the second plate 14 in sequence.
