[0039] Working principle: When the present invention is used, first select a bag for the sample, then place the device on top of the bag, fix the device first, manually rotate the threaded rod 9, thereby driving the slider Ⅰ10 to slide, and the slider Ⅰ10 will squeeze the slide bar 7 to both sides through the connecting rod 8, and when the slide bar 7 slides to both sides, the inclined surface on the slide bar 7 will squeeze the inclined surface on the squeezing plate 6, thereby driving the squeezing plate 6 to slide on the round rod on the extension plate 4, and when the squeezing plate 6 slides, it will squeeze the protruding small plate on the upper end of the clamping jaw 1, thereby driving the clamping jaw 1 to rotate, so that the clamping jaw 1 clamps the two ends of the bag to complete the fixation; Then, the sampling position is selected by sliding the center frame 21. After selecting the approximate position, the slider II 11 on the slide rail I 20 is slid to select the precise position. After selecting the position, the sampler 13 is pressed downward by hand to insert the sharp point at the lower end of the sampler 13 into the starch bag. After being inserted to a certain depth, the starch will fill the interior of the sampler 13 and the sample tube 14, and due to the adhesion characteristics of the starch, it will not fall out. Then the sampler 13 is pulled out. When pulling it out, the clamping rod I 12 slides in the slide groove on the side of the sampler 13 until the clamping rod I 12 slides to the lowermost end of the slide groove on the sampler 13, so that the sampler 13 stops at an accurate position. Then the electric push rod 16 is started, driving the slider III 15 to retract inward, thereby driving the support rod 17 inward. When moving, the clamp 18 on the support rod 17 clamps the outer wall of the sample tube 14, and the card 19 is inserted into the gap on the sample tube 14, so as to fix and seal the starch sample in the sample tube 14, and then the electric push rod 16 is pushed outward again, so that the clamp 18 separates the sample tube 14 from the sampler 13, and the sampling is completed. Finally, the sample tube 14 is removed from the clamp 18 by hand to be stored for testing. When the sample tube 14 is manually removed from the clamp 18, since the card 19 is lightly stuck in the slot on the support rod 17, and the friction of the card 19 stuck in the gap of the sample tube 14 is greater, the card 19 will remain in the gap of the sample tube 14; in this way, the two sample tubes 14 on the device can take samples at different positions.
