The guide plate 304 can limit the guide rod 306. The guide plate 304 is fixed in the collection box 301, and the movable frame 303 is slidably connected to the guide plate 304 through the guide rod 306, wherein the length of the guide rod 306 on both sides is greater than that of the middle guide rod 306, and the guide rod 306 on both sides extends to the outside of the collection box 301, and an adjusting screw rod 305 is threadedly connected to the middle part of the top of the collection box 301, and quantitative collection and increased exhaust speed can be achieved by rotating the adjusting screw rod 305.

[0024] like Figure 1-Figure 2 As shown, the extraction mechanism 2 includes an extraction box 201, an air inlet pipe 202, a processing box 203, a filter screen 204 and a pump 205, which facilitates the extraction of air through the extraction mechanism 2.

[0025] like Figure 1-Figure 2 As shown, the air inlet pipe 202 is fixed in the middle of the top of the extraction box 201, and the air inlet pipe 202 is flush with the top of the extraction box 201, and a plug 7 is installed on the air inlet pipe 202 to facilitate the entry of air through the air inlet pipe 202, and the plug 7 can be used to seal the air inlet pipe 202 when not in use.

[0026] like Figure 1-Figure 2 As shown, the filter 204 is fixed in the middle of the extraction box 201. The air entering the processing box 203 through the air inlet pipe 202 can be filtered by the filter 204. The bottom end of the air inlet pipe 202 extends into the processing box 203. The pump 205 is connected to the bottom end of the extraction box 201 through a pipeline, and the filtered gas is extracted by the pump 205.
