Through regular training courses, seminars and other activities, the latest sampling technologies and methods can be popularized, and the operational capabilities and biosafety awareness of sampling personnel can be improved. At the same time, establish complete sampling standards and operating specifications to ensure the scientificity and accuracy of the sampling process. In short, animal epidemic prevention supervision sampling devices play an important role in animal epidemic prevention work. Future research and application should pay more attention to technological innovation, biosafety protection and personnel training to promote the continuous progress and development of animal epidemic prevention work.

The present invention does not need to replace a new sampling tube 15 after each sampling, which saves time and improves work efficiency.

[0040] Furthermore, a door panel is detachably connected to the side of the box body 1 to facilitate taking out the sample and replacing the new empty sampling tube 15.

[0041] Furthermore, a lighting lamp may be installed on the bottom surface of the box body 1 to facilitate sampling in an environment with insufficient lighting conditions.

[0049] Further optimization scheme, the bottom surface of the adjustment plate 7 is symmetrically fixed with a connecting plate 11, and the sleeve 2 is symmetrically provided with slide grooves 10 on both sides. The bottom of the connecting plate 11 is located in the slide groove 10 and is slidably connected with the slide groove 10. The outside of the slide groove 10 is marked with scales, and a locking knob 12 is installed at the bottom of the connecting plate 11. The locking knob 12 is threadedly connected with the inner wall of the slide groove 10. When adjusting the adjustment plate 7, first loosen the locking knob 12, adjust the adjustment plate 7 to a suitable position according to the scale, and drive the connecting plate 11 to slide in the slide groove 10, and then tighten the locking knob 12 to fix it.
