[0024] In the specific implementation process, as Figures 1 - 4 shown, it includes a triangular bracket 1 and a detector 2. A base 3 is provided at the top of the triangular bracket 1. Four support legs 9 are fixedly arranged at the bottom of the detector 2 in a square shape, which facilitates temporarily placing the detector 2 on the ground.

[0025] A cylindrical platform 4 is movably arranged on the base 3. A first connecting seat 5 is fixed at the top of the cylindrical platform 4. A number of clamping columns 6 are fixedly arranged in a ring on the first connecting seat 5. A second connecting seat 7 is fixed at the bottom of the detector 2. A number of card slots 8 are formed in a ring at the bottom of the second connecting seat 7. The clamping columns 6 are fitted with the card slots 8. A worm gear 10 is installed on the cylindrical platform 4. Two limit seats 11 are spaced apart and installed on the base 3. A worm 12 is movably arranged between the two limit seats 11. The worm 12 is meshed with the worm gear 10. The worm 12 is an Archimedean worm. One end of the worm 12 extends out of the limit seat 11 and is installed with a hand crank 13. When it is necessary to adjust the orientation of the air extraction port 14, the staff only needs to rotate the hand crank 13 to drive the worm 12 to rotate. Under the transmission action of the worm 12 and the worm gear 10, the entire cylindrical platform 4 rotates to drive the detector 2 and the air extraction port 14 to adjust the position, without having to move the entire triangular bracket 1 and the detector 2 again, which saves time and effort.

[0026] An air extraction port 14 and an air inlet 15 are arranged on one side of the detector 2. A side seat 16 is fixed on one side of the detector 2. A plurality of through slots 17 are formed in the side seat 16. A drying cylinder 18 is placed at the through slots 17. The drying cylinder 18 is connected to the air inlet 15 through a hose. Limiting half rings 19 are arranged on both sides of the through slots 17. The drying cylinder 18 is located between the two limiting half rings 19. Elastic pads 20 are arranged on the surface of the limiting half rings 19. When installing the drying cylinder 18, only need to directly insert the drying cylinder 18 into the through slots 17. Under the action of the two limiting half rings 19 and the elastic pads 20, the drying cylinder 18 can be stably limited inside the through slots 17, as Figure 3As shown, an absorption bottle with solution is provided on the detector 2. When in use, an additional hose needs to be prepared. One end of the hose is inserted into the interior of the drying cylinder 18, and the other end is inserted into the interior of the absorption bottle. For the specific working steps, reference can be made to the JCH-6120 particulate matter comprehensive sampler.

[0027] Working principle of the present utility model: When this device is in use, the triangular bracket can be first unfolded in the area to be sampled, and then the card slot 8 at the bottom of the detector 2 can be snapped into the interior of the card post 6 to complete the assembly of the detector 2 and the triangular bracket 1. The operation is simple and convenient and is easy to disassemble and assemble;

[0028] When it is necessary to adjust the orientation of the air extraction port 14, the staff only needs to rotate the crank 13 to drive the worm 12 to rotate. Under the transmission of the worm 12 and the worm gear 10, the entire columnar platform 4 rotates to drive the detector 2 and the air extraction port 14 to adjust their positions, without the need to re-move the entire triangular bracket 1 and the detector 2, saving time and effort;

[0029] When installing the drying cylinder 18, only need to directly insert the drying cylinder 18 into the through groove 17. Under the action of the two limiting half-rings 19 and the elastic pad 20, the drying cylinder 18 can be stably limited within the through groove 17.
