After the first filter plate 11 is cleaned, the first filter plate 11 and the dustproof box 1 can be connected through the elastic action of the spring 14. This step can reduce the accumulation of dust in the middle part of the first filter plate 11 when the test fixture is dust-proof. When the dust in the middle part of the first filter plate 11 needs to be cleaned, the first filter plate 11 can be conveniently taken out from the middle part of the dustproof box 1, so as to protect the test fixture and reduce the unstable results of the test fixture due to dust pollution.
[0025] like Figure 2-4As shown, an air duct 2 is fixedly connected to the middle of the dustproof box 1; the end of the air duct 2 is located at the bottom of the first filter plate 11; a support rod 21 is fixedly connected to the end of the air duct 2; a fan 22 is fixedly connected to the end of the support rod 21; a collecting chamber 23 is fixedly connected to the middle of the dustproof box 1; the fan 22 is located inside the collecting chamber 23; when working, when the first filter plate 11 is used to block external dust, the fan 22 at the end of the support rod 21 can be operated, and then the smaller dust at the bottom of the first filter plate 11 can be adsorbed through the air duct 2, and the dust can be adsorbed inside the collecting chamber 23. At this time, the second filter plate 18 can reduce the smaller dust from entering the interior of the dustproof box 1. This step can reduce the smaller dust from entering the interior of the dustproof box 1 through the second filter plate 18 through the adsorption effect of the fan 22, and the occurrence of pollution to the test fixture caused by the smaller dust, thereby reducing the occurrence of inaccurate test results when the test fixture is in use.
[0026] like Figure 2-5 As shown, a rotating shaft 3 is fixedly connected to the middle of the dustproof box 1; a straight plate 31 is rotatably connected to the middle of the rotating shaft 3; a plurality of cleaning brushes 32 are fixedly connected to the middle of the straight plate 31; a rubber pad 33 is fixedly connected to the middle of the rotating shaft 3; the rubber pad 33 is slidably connected to the straight plate 31; during operation, when the first filter plate 11 is used to block dust, the straight plate 31 can be rotated in the middle of the rotating shaft 3, and then the dust accumulated in the middle of the first filter plate 11 can be cleaned by the cleaning brush 32, and the rubber pad 33 can limit the position of the straight plate 31. This step can clean the dust accumulated in the middle of the first filter plate 11 when the first filter plate 11 is used to protect the test fixture from dust, thereby improving the protection effect of the test fixture and reducing the occurrence of dust contamination of the test fixture.
[0027] like Figure 1-2 As shown, the middle part of the collecting chamber 23 is rotatably connected with a cover plate 4; the inside of the collecting chamber 23 is slidably connected with a scraper 41; the middle part of the scraper 41 is fixedly connected with a pull rod 42; during operation, when a lot of dust is accumulated in the collecting chamber 23, the cover plate 4 can be rotated in the middle part of the collecting chamber 23, and then the pull rod 42 can be pulled to make the scraper 41 clean the dust accumulated in the middle part of the collecting chamber 23. This step can reduce the accumulation of dust in the collecting chamber 23, and then reduce the occurrence of dust entering the dustproof box 1, thereby improving the accuracy of the test results when the test fixture is used.
[0028] like Figure 1-2As shown, a vibration ball 5 is fixedly connected to the middle of the dustproof box 1; the vibration ball 5 is slidably connected to the bottom of the collecting chamber 23; during operation, when the dust inside the collecting chamber 23 is cleaned, the vibration ball 5 can be vibrated, and then the collecting chamber 23 can be vibrated under the knocking action of the vibration ball 5. This step can reduce the situation in which dust accumulation in the middle of the collecting chamber 23 makes it difficult to clean, thereby improving the dust cleaning efficiency.

[0031] Working principle: during operation, when the test fixture is in use, it can be placed inside the dustproof box 1. At this time, the dustproof box 1 can be used to wrap it, and then the first filter plate 11 can be used to isolate the dust from the outside. When the middle part of the first filter plate 11 is blocked due to excessive dust, the pull column 17 can be pushed to make it slide inside the slide groove 16, and then the insert block 15 can be pushed to the inside of the slot 13, and then the first filter plate 11 can be taken out from the middle part of the dustproof box 1.

This step can reduce the accumulation of dust in the middle part of the first filter plate 11 when the test fixture is dust-proof. When cleaning the dust on the outside, the first filter plate 11 can be conveniently taken out from the middle of the dustproof box 1, thereby protecting the test fixture and reducing the unstable results of the test fixture caused by dust pollution. When using the first filter plate 11 to block the external dust, the fan 22 at the end of the support rod 21 can be operated, and then the smaller dust at the bottom of the first filter plate 11 can be adsorbed through the air duct 2, and the dust can be adsorbed inside the collecting chamber 23. At this time, the second filter plate 18 can reduce the smaller dust from entering the interior of the dustproof box 1. This step can reduce the smaller dust from entering the interior of the dustproof box 1 through the second filter plate 18 through the adsorption effect of the fan 22, and thereby reduce the test fixture from being polluted. When in use, the test results may be inaccurate. When the first filter plate 11 is used to block dust, the straight plate 31 can be rotated in the middle of the rotating shaft 3, and then the dust accumulated in the middle of the first filter plate 11 can be cleaned by the cleaning brush 32. The rubber pad 33 can limit the position of the straight plate 31. This step can be used to clean the dust accumulated in the middle of the first filter plate 11 when the first filter plate 11 is used to protect the test fixture from dust, thereby improving the protection effect of the test fixture and reducing the contamination of the test fixture by dust. When a lot of dust is accumulated in the collection chamber 23, the cover plate 4 can be rotated in the middle of the collection chamber 23, and then the pull rod 42 can be pulled to make the scraper 41 clean the dust accumulated in the middle of the collection chamber 23. This step can reduce the accumulation of dust inside the collection chamber 23, and further reduce the occurrence of dust entering the dustproof box 1, thereby improving the accuracy of the test results when the test fixture is used. When cleaning the dust inside the collection chamber 23, the vibration ball 5 can be vibrated, and then the collection chamber 23 can be vibrated under the knocking action of the vibration ball 5. This step can reduce the occurrence of dust accumulation in the middle of the collection chamber 23 that makes it difficult to clean, and further improve the cleaning efficiency of the dust. When using the cleaning brush 32 to clean the dust in the middle of the first filter plate 11, the support column 6 can be used to support the end of the straight plate 31. This step can reduce the skewness of the position of the straight plate 31 when using the cleaning brush 32 to clean the dust in the middle of the first filter plate 11.This can improve the cleaning efficiency of the dust in the middle of the first filter plate 11. When the dust is adsorbed into the collection chamber 23, the gas can be exhausted to the outside through the valve 7.
