[0053] The sealing fitting part 1 is conical as a whole, is provided with a sealing fitting hole 111 on the inner side, and forms a wide mouth on the outer side. The protector 4 is located on one side of the wide mouth end of the sealing fitting part 1, and shields the wide mouth to prevent impurities and dust from entering the puncture sleeve 200 through the wide mouth. When the puncture rod 300 penetrates into the sealing assembly 100, the protector 4 will deform under the action of external force, avoid the puncture rod 300, and enable the puncture rod 300 to smoothly pass through the protector 4.

[0054] The second sealing ring 3 is provided with a second fixed column 32 on the side away from each first fixed column 31, the second fixed column 32 sequentially passes through the second through hole 411 on the protector 4, the third through hole 51 on the annular shell 5, and is connected to the second fixed fitting hole 61 on the third sealing ring 6, so that the first sealing ring 2, the sealing fitting part 1, the second sealing ring 3, the protector 4, the annular shell 5, and the third sealing ring 6 are sequentially stacked and assembled and fixed into an integrated structure, facilitating unified assembly on the shell 7.

[0055] In some possible embodiments, in combination Figure 7 and Figure 9 As shown, the second fixed column 32 extends out of the second fixed fitting hole 61, and one end of the second fixed column 32 extending out of the second fixed fitting hole 61 is hot-melt connected to the third sealing ring 6.
