[0038] The structure and use principle of the fixing component 4, sampling component 6 and driving mechanism 7 in the utility model have been disclosed in a sampling device for food safety detection disclosed in Chinese patent application No. 202121907278.9. Its working principle is that when sampling food, the support frame 1 is first fixed, and the two electric push rods 5 drive the horizontal plate to move up and down as a whole, and the driving mechanism 7 drives the hollow column to rotate until the hollow column as a whole moves to the deep part of the food, and the adjusting motor drives the screw to rotate, thereby driving the baffle to move as a whole until the feed port coincides with the feed hole. At this time, the deep sample falls from the feed port and the feed hole to the inside of the collection box in turn, so as to realize sample sampling of different depths. After the sampling is completed, the adjusting motor is displaced again by the screw to make the baffle block the feed port again to prevent the deep sample from being contaminated by the shallow sample. The adjusting rod can be turned to remove the plate, and then the collection box can be taken out from the inside of the hollow column.

[0039] The working principle and use process of the utility model: the utility model is used for sampling food during food safety testing. When in use, the connecting frame 3 is adjusted to a suitable position through the adjusting component 2 according to the needs of use, and then the device is fixed by the fixing component 4, so that it can be used. When in use, the sampling component 6 is driven downward by the electric push rod 5, so as to cooperate with the driving mechanism 7 so that the sampling component 6 moves downward to a suitable position for sampling. When the driving mechanism 7 is in use, the heat dissipation component 9 is used to dissipate heat from the driving motor in the protective cover 8 to prevent the situation where heat cannot be discharged and affects the use. When the adjusting component 2 is in use, the turning handle 24 is rotated, and the turning handle 24 rotates to drive the bevel gear 23 to rotate, and the bevel gear 23 rotates to drive the bevel gear 1 22 to rotate, and the bevel gear 1 22 rotates to drive the bidirectional threaded screw 21 to rotate, and the bidirectional threaded screw 21 rotates to drive the adjusting plate 25 to move, so as to adjust the connecting frame 3. The position of the connecting frame 3 is adjusted. After the adjustment is completed, the threaded rod 27 is rotated, and the threaded rod 27 drives the damping block 26 to move, and the handle 24 is tightened, so that the position of the connecting frame 3 can be conveniently adjusted according to the needs of use when the device is in use, thereby improving the practicality of use. When the heat dissipation component 9 is in use, the heat dissipation fan 91 is started, and the wind is filtered through the filter screen 92 and then enters to blow out the heat in the protective cover 8. When the filter screen 92 needs to be cleaned, the cleaning motor 93 is started, and the cleaning motor 93 drives the cleaning brush plate 95 to rotate to clean the filter screen 92. When the cleaning brush plate 95 needs to be replaced, the clamping rod 96 is pressed, and the clamping rod 96 drives the clamping slider 97 to move and compress the clamping spring 98, so that the clamping rod 96 is disengaged from the clamping hole, so that the cleaning brush plate 95 can be removed, so that the device is convenient for dissipating the heat of the drive motor when in use, to prevent the heat from not being able to dissipate in a sealed environment and causing damage to it.
