Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a food sampling device for food detection, including a protective shell 3. A sampling rod 9 is rotatably connected inside the protective shell 3. The protective shell 3 is used to protect the sampling rod 9, and the sampling rod 9 is used to sample and preserve food. A plurality of uniformly distributed sampling grooves 2 are opened inside both the protective shell 3 and the sampling rod 9. A storage bin is opened inside the sampling rod 9. Food samples can enter the storage bin through the sampling grooves 2 for storage. A connecting shaft 7 is fixedly connected to the top end of the sampling rod 9. A rotating shaft 5 is arranged at the top end of the connecting shaft 7. A rotating rod 6 is fixedly connected inside the top end of the rotating shaft 5. The connecting shaft 7 is used to connect the sampling rod 9 and the rotating shaft 5 to each other. Rotating the rotating rod 6 can drive the sampling rod 9 to rotate through the rotating shaft 5. A gear 8 is fixedly connected to the outer periphery of the connecting shaft 7. An installation rod 15 is arranged inside the top end of the protective shell 3. A support shaft 14 is rotatably connected to the middle of the installation rod 15. The bottom end of the support shaft 14 is fixedly connected to the inner side of the top of the protective shell 3. One end of the installation rod 15 is fixedly connected to an installation plate 17. The installation rod 15 is used to drive the installation plate 17 to rotate around the support shaft 14. A plurality of uniformly distributed teeth 18 are fixedly connected to one side of the installation plate 17. The teeth 18 are meshed with the gear 8. The installation plate 17 serves to install the teeth 18. The meshing of the teeth 18 and the gear 8 can block the rotation of the connecting shaft 7. A second spring 16 is fixedly connected to one side of the installation rod 15. One end of the second spring 16 is fixedly connected to the inside of the protective shell 3. The second spring 16 is used to push the teeth 18 into contact with the gear 8. The other end of the installation rod 15 is rotatably connected to a fixing rod 13. The fixing rod 13 is slidably connected to the inside of the top end of the protective shell 3. Pulling the fixing rod 13 can drive the installation rod 15 to rotate so that the teeth 18 are separated from the gear 8.

[0035] Refer to Figure 1 , Figure 2 and Figure 4, a connection component is provided at the top end of the rotating shaft 5. The connection component includes a mounting block 1. The mounting block 1 is fixedly connected to the bottom end of the rotating shaft 5. The mounting block 1 abuts against the top end of the protective shell 3. The top end of the connecting shaft 7 is slidably connected inside the mounting block 1. The top end of the connecting shaft 7 is inserted into the mounting block 1 to connect the connecting shaft 7 and the rotating shaft 5 to each other. A moving shaft 12 is slidably connected inside the mounting block 1. A first spring 11 is sleeved on the outer periphery of the moving shaft 12. One end of the first spring 11 abuts against the right side of the mounting block 1, and the other end of the first spring 11 abuts against the left end of the moving shaft 12. The first spring 11 is used to push the moving shaft 12 to move. Connecting rods 19 are rotatably connected to both the front and rear sides of the left end of the moving shaft 12. One end of the connecting rod 19 is rotatably connected to a fixed shaft 20. One end of the fixed shaft 20 is slidably connected inside the top end of the connecting shaft 7. The movement of the moving shaft 12 can drive the connecting rod 19 to rotate, and the connecting rod 19 drives the fixed shaft 20 to move. One end of the fixed shaft 20 is inserted into the connecting shaft 7 to fix the connecting shaft 7 inside the mounting block 1. A through hole 10 is opened inside the top end of the protective shell 3. The through hole 10 is provided at the bottom of the gear 8. Opening the through hole 10 facilitates taking out the sampling rod 9 from inside the protective shell 3.

[0036] Refer to Figure 1 , Figure 6 , a limiting plate 23 is rotatably connected inside the top end of the fixed rod 13. A fixing groove 4 is opened inside the top end of the protective shell 3. The limiting plate 23 is slidably connected inside the fixing groove 4. The limiting plate 23 is inserted into the fixing groove 4 to fix the position of the tooth 18, so that the tooth 18 remains in a state separated from the gear 8.

[0037] Refer to Figure 1 , Figure 5 , a limiting block 21 is fixedly connected to the outer periphery of the sampling rod 9. A limiting groove 22 is opened inside the protective shell 3. The limiting block 21 is slidably connected inside the limiting groove 22. The sliding of the limiting block 21 inside the limiting groove 22 can limit the rotation of the sampling rod 9.

[0038] Working principle: When using this device, insert the protective shell 3 into the food. Then, push the fixing rod 13 to rotate and insert the limiting plate 23 into the fixing groove 4, so that the mounting rod 15 drives the mounting plate 17 and the teeth 18 to rotate and keeps the teeth 18 separated from the gear 8. Then, hold the protective shell 3 by hand and push the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the sampling rod 9 to rotate. When the sampling groove 2 inside the sampling rod 9 coincides with the sampling groove 2 inside the protective shell 3, the food can enter the sampling rod 9 through the sampling groove 2 to complete the sampling. Then, push the rotating rod 6 to rotate in the reverse direction so that the sampling groove 2 inside the sampling rod 9 no longer coincides with the sampling groove 2 inside the protective shell 3, thus storing the food sample inside the sampling rod 9. Take out the limiting plate 23 from the fixing groove 4, and the mounting rod 15 will be pushed by the second spring 16 to rotate, making multiple teeth 18 engage with the gear 8, so as to fixedly connect the shaft 7 to prevent the sampling rod 9 from continuing to rotate and causing the food sample to fall out. When the sampling rod 9 needs to be cleaned, the moving shaft 12 can be pressed into the mounting block 1 to move. During the movement of the moving shaft 12, it drives the two connecting rods 19 to rotate. The rotation of the two connecting rods 19 respectively drives the two fixing shafts 20 to move. When one end of the fixing shaft 20 is pulled out from the connecting shaft 7, the top end of the connecting shaft 7 can be taken out from the mounting block 1. Then, the sampling rod 9 can be taken out from the protective shell 3 and cleaned to prevent impurities from accumulating inside the sampling rod 9 and contaminating the food sample.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
