By rotating the second sealing gasket 39 to open it, and then pulling the first pull block 37 to the right and the second pull block 38 to the left, the second connecting spring 36 is compressed.

The relative movement of the two connecting rods 33 can make the two first sleeves 31 move relative to each other, and the first connecting spring 32 is compressed. When the first sleeve 31 is detached from the recess opened on the inner wall of the upper connecting tube 24, the dust screen 29 is pulled upward, and the dust on the dust screen 29 can be easily cleaned.
