A sampling component 2 is arranged inside the main body rod 1, and a holding component 3 is arranged at the bottom of the main body rod 1. The sampling component 2 includes a moving rod 22, and the moving rod 22 is inserted into the main body rod 1. The holding component 3 includes a holding cylinder 31, and a fixed rod 33 is fixedly installed inside the holding cylinder 31. A screw rod 34 is fixedly installed at the top of the fixed rod 33.

The bottom of the moving rod 22 is flush with the bottom of the main body rod 1, the top of the holding cylinder 31 fits against the bottom of the main body rod 1, and the outer diameter of the holding cylinder 31 is the same as the outer diameter of the main body rod 1.

[0029] A round head 32 is fixedly installed at the bottom of the holding cylinder 31, the round head 32 is semi-circular, and the diameter of the round head 32 is the same as the diameter of the holding cylinder 31. A cross plate 21 is fixedly installed at the top of the main body rod 1, and a push plate 23 is fixedly installed at the top of the moving rod 22.

[0030] A sliding groove 24 is formed inside the main body rod 1, a sliding plate 25 is slidably connected inside the sliding groove 24, the sliding plate 25 is fixedly installed on the outer side of the moving rod 22, the moving rod 22 penetrates through the inside of the sliding groove 24 up and down, and a spring 26 is fixedly installed between the bottom of the sliding plate 25 and the inner bottom of the sliding groove 24. The spring 26 is sleeved on the outer side of the moving rod 22. The cross-sectional shape of the sliding groove 24 and the cross-sectional shape of the sliding plate 25 are both rectangular, and the outer side of the sliding plate 25 fits against the outer side of the sliding groove 24.

[0031] In this embodiment, during sampling, hold the main body rod 1 by the cross plate 21, and insert the holding cylinder 31 and the main body rod 1 into the food sample through the round head 32. After insertion, press the push plate 23 to move the moving rod 22 downward, and the sliding plate 25 moves downward synchronously, and the spring 26 contracts. The downward movement of the moving rod 22 can push the lower fixed rod 33 and the holding cylinder 31 downward. After the holding cylinder 31 moves away from the main body rod 1, external granular food flows into the holding cylinder 31 through the upper part of the holding cylinder 31, realizing the sampling of the food, and during sampling, the depth of insertion of the holding cylinder 31 can be controlled to sample food samples at different depths. After sampling, pull the push plate 23 in the opposite direction, and under the action of the elastic force and the pulling force of the spring 26, the holding cylinder 31 fits against the bottom of the main body rod 1 again, so that the sampled sample can be wrapped inside the holding cylinder 31, and then the whole is taken out from the sample. When taking out, the sample located inside the holding cylinder 31 will not be mixed with the sample located outside the upper layer, ensuring that the taken-out samples are all samples near the insertion depth.

[0032] Refer to Figures 1 to 5, in one aspect of this embodiment, the storage component 4 includes a base 41 and a support plate 42. The support plate 42 is located above the base 41. Side plates 45 are fixedly installed at the left and right ends of the base 41 and between the upper and lower base 41 and the support plate 42.

The containing cylinder 31 passes through the inside of the slot 44, and the round head 32 is located inside the fixing groove 43.

[0033] In this embodiment, after the sample sampling is completed, by rotating the containing cylinder 31 to drive the internal screw 34 to rotate, the screw 34 can rotate out from the internal thread hole 35. After the screw 34 is removed from the internal thread hole 35, the removal of the containing cylinder 31 can be realized. When the screw 34 rotates, the movement of the moving rod 22 is ensured not to rotate along with it through the restriction of the direction sliding plate 25 and the sliding groove 24, ensuring that the screw 34 can correctly move out from the internal thread hole 35. After the containing cylinder 31 is disassembled, the containing cylinder 31 containing the sample is inserted into the slot 44, and the round head 32 is inserted into the slot 44, so as to store the sampled containing cylinder 31 through the base 41 and the support plate 42. Moreover, multiple containing cylinders 31 are respectively stored on the base 41 and the support plate 42 at different positions, achieving the effect of convenient classification storage of the sampled samples.

[0034] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Working principle: During sampling, hold the main body rod 1 by the cross plate 21, and insert the containing cylinder 31 and the main body rod 1 into the food sample through the round head 32. After insertion, press the push plate 23 to move the moving rod 22 downward. The sliding plate 25 moves downward synchronously, and the spring 26 contracts. The downward movement of the moving rod 22 can push the lower fixed rod 33 and the containing cylinder 31 downward. After the containing cylinder 31 moves away from the main body rod 1, the external granular food flows into the interior of the containing cylinder 31 through the upper part of the containing cylinder 31, realizing the sampling of the food. And during sampling, the depth of insertion of the containing cylinder 31 can be controlled to sample food samples at different depths. After sampling is completed, pull the push plate 23 in the opposite direction. Under the action of the elastic force and pulling force of the spring 26, the containing cylinder 31 is attached to the bottom of the main body rod 1 again, so that the sampled sample can be wrapped inside the containing cylinder 31, and then the whole is taken out from the sample. When taking out, the sample inside the containing cylinder 31 will not be mixed with the sample outside the upper layer, ensuring that the taken-out samples are all samples near the insertion depth. After the sample sampling is completed, rotate the containing cylinder 31 to drive the internal screw rod 34 to rotate. The rotation of the screw rod 34 can be removed from the internal thread hole 35. After the screw rod 34 is removed from the internal thread hole 35, the removal of the containing cylinder 31 can be realized. And when the screw rod 34 rotates, the movement of the moving rod 22 is ensured not to rotate along with it through the restriction of the directional sliding plate 25 and the sliding groove 24, ensuring that the screw rod 34 can be correctly removed from the internal thread hole 35. After the containing cylinder 31 is disassembled, insert the containing cylinder 31 containing the sample into the slot 44, and insert the round head 32 into the slot 44, so as to store the sampled containing cylinder 31 through the base 41 and the support plate 42. And multiple containing cylinders 31 are respectively stored on the bases 41 and support plates 42 at different positions, realizing the effect of convenient classification storage of the sampled samples.
