When the threaded ring 44 is separated from the mounting rod 43, the connecting ring 301 is then moved to drive the lug plate 41, so that the mounting hole 42 on the lug plate 41 is separated from the mounting rod 43. After the mounting hole 42 on the lug plate 41 is separated from the mounting rod 43, the disassembly of the filter assembly 3 is completed. Then personnel can repair the disassembled filter assembly 3.
