the two first elastic sheets 41, the two second elastic sheets 42 and the two sealing half-tubes 43, the two first elastic sheets 41 are disposed on a side wall of the shell-side partition plate 3, and the two first elastic sheets 41 are disposed oppositely. The two second elastic pieces 42 are arranged on the other side wall of the shell-side partition plate 3, and the two second elastic pieces 42 are arranged oppositely. After the first elastic sheet 41 and the second elastic sheet 42 are installed, an installation groove is formed between the first elastic sheet 41 and the second elastic sheet 42 which are located at the same end. The two seal half pipes 43 are arranged along the axial direction of the cylinder 1 and are located on opposite side walls of the cylinder 1. When the shell side partition plate 3 is installed in the cylinder body 1, the sealing half-tube 43 is positioned in the installation groove, so that the first elastic sheet 41 and the second elastic sheet 42 are in elastic contact with the sealing half-tube 43, and the sealing function is realized through elastic contact.
