[0030] The fixing assembly includes a fixing plate 19, and the two fixing plates 19 are symmetrically arranged on the mounting tube 11. A first fixing hole is provided on one side of the fixing plate 19, and a second fixing hole is provided on one side of the box body 29 at a position corresponding to the first fixing hole. A buckle nail 20 is provided in each of the second fixing holes. When in use, the mounting tube 11 is installed in the mounting hole on the box body 29, and then the first fixing hole on one side of the fixing plate 19 is aligned with the position of the second fixing hole on the box body 29, and the two buckle nails 20 are respectively installed in the first fixing hole and the second fixing hole to fix the position of the mounting tube 11. It is worth noting that the buckle nail 20 is an existing component and can be selected according to actual use.
[0031] The adjusting mechanism comprises an adjusting air-permeable plate 16, wherein the adjusting air-permeable plate 16 is arranged inside the mounting tube 11, wherein one side of the adjusting air-permeable plate 16 is in close contact with one side of the fixed air-permeable plate 15, wherein a limiting column is fixedly arranged on one side of the fixed air-permeable plate 15, wherein a circular perforation is arranged at a position corresponding to the limiting column on one side of the adjusting air-permeable plate 16, wherein the fixed air-permeable plate 15 and the adjusting air-permeable plate 16 are both provided with a plurality of air holes 17, wherein the air holes 17 are arranged in an arc shape, wherein a plurality of the air holes 17 are arranged in an array and their diameters are increased at equal intervals, wherein four groups of air holes 17 are arranged on the fixed air-permeable plate 15 and the adjusting air-permeable plate 16, wherein the positions of two adjacent groups of the air holes 17 are staggered, and a stop bar 18 is formed between two air holes 17 in the same column, and when in use, at the initial position, the stop bar 18 on the adjusting air-permeable plate 16 8 overlaps with the air holes 17 on the fixed air-permeable plate 15, so that several air holes 17 on the fixed air-permeable plate 15 are closed, so that the installation tube 11 is closed. When the air permeability inside the installation tube 11 needs to be adjusted, the air-permeable plate 16 is rotated to make the stopper 18 on the adjusting air-permeable plate 16 gradually separate from the air holes 17 on the fixed air-permeable plate 15, thereby adjusting the air permeability of the nuclear pore membrane body 12. When the adjusting air-permeable plate 16 is rotated 90 degrees, the stopper 18 on the adjusting air-permeable plate 16 completely overlaps with the stopper 18 on the air holes 17, so that the air holes 17 on the adjusting air-permeable plate 16 overlap with the air holes 17 on the fixed air-permeable plate 15, so that the air permeability of the nuclear pore membrane body 12 reaches the maximum.

A mounting plate is fixedly arranged inside the fixing box 25, and a return spring 26 is fixedly arranged on one side of the return spring 26, and one end of the two return springs 26 is fixedly connected to both sides of the mounting plate respectively. Each of the stop blocks 22 is tightly attached to the inner side of the stop ring 21, and the stop ring 21 is fixed inside the mounting tube 11. During use, when the adjustable air-permeable plate 16 needs to be adjusted, the two stop blocks 22 are pulled to move by the two paddles and the connecting rod 23, so that the stop blocks 22 are separated from the inner side of the stop ring 21, and then the adjustable air-permeable plate 16 is driven to rotate by the paddles to adjust the air permeability of the nuclear pore membrane body 12. After the adjustment is completed, the paddles are released, and under the action of the reset spring 26, the stop blocks 22 are tightly attached to the inner side of the stop ring 21, thereby fixing the position of the adjustable air-permeable plate 16.
[0033] The inner side of the stop ring 21 is provided with a plurality of stop grooves, and the stop block 22 is fixedly provided with a plurality of stop strips. When in use, the stop strips cooperate with the stop grooves to increase the fixing effect of the adjustable air-permeable plate 16.

In the initial position, the stop bar 18 on the air permeable plate 16 is adjusted to coincide with the air permeable hole 17 on the fixed air permeable plate 15, so that several air permeable holes 17 on the fixed air permeable plate 15 are closed, so that the installation tube 11 is closed. When the air permeability inside the installation tube 11 needs to be adjusted, the two stop blocks 22 are pulled to move by the two dial plates and the connecting rod 23, so that the stop blocks 22 is separated from the inner side of the stop ring 21, and then the adjusting air-permeable plate 16 is driven to rotate through the dial plate, so that the upper bar 18 of the adjusting air-permeable plate 16 gradually separates from the air hole 17 on the fixed air-permeable plate 15, thereby adjusting the air permeability of the nuclear pore membrane body 12. When the adjusting air-permeable plate 16 is rotated 90 degrees, the bar 18 on the adjusting air-permeable plate 16 and the bar 18 on the air hole 17 completely overlap, so that the air hole 17 on the adjusting air-permeable plate 16 overlaps with the air hole 17 on the fixed air-permeable plate 15, so that the air permeability of the nuclear pore membrane body 12 reaches the maximum. After the adjustment is completed, the dial plate is released, and under the action of the reset spring 26, the stop block 22 is tightly attached to the inner side of the stop ring 21, thereby fixing the position of the adjusting air-permeable plate 16.
