Amount, a micro-adjustment hole is opened through the middle of the adjustment main frame 6, and the ventilation amount can be finely adjusted through the micro-adjustment hole, so that the control is more precise and the adjustable range can be further increased. A micro-adjustment sealing plate 10 for sealing the micro-adjustment hole is movably connected to the connecting tube 3. The range of opening the micro-adjustment hole can be adjusted by moving the micro-adjustment sealing plate 10 to control the ventilation amount and cooperate with the adjustment of the adjustment main frame 6 to make the adjustment more precise.

The adjustment main frame 6 is provided with an adjustment limit indicator mark 9 corresponding to the first identification scale line 7 and the second identification scale line 8. The rotation of the first adjusting collar 2 and the second adjusting collar 5 can make the first identification scale line 7 and the second identification scale line 8 rotate relative to each other. The first identification scale line 7 and the second identification scale line 8 are opposite to the adjustment limit indicator mark 9, so as to intuitively distinguish the degree of rotation adjustment, thereby making it more convenient to use.

[0022] See also Figures 1 to 6 The adjusting main frame 6 is a two-layer sleeve structure. By adjusting the double-layer connection of the main frame 6, the length of the connection gap therebetween can be increased to ensure the airtightness of the connection, thereby making its sealing better.
