[0027] The reagent tubes containing food test samples are stored by the placement mechanism 3, and then the placement mechanism 3 is limited by the limiting mechanism 4 so that the placement mechanism 3 cannot move. Then the air in the storage box 1 is purified by the purification mechanism to prevent the food test samples from spoiling.

[0028] like Figure 2 As shown, a spring 22 is fixedly connected to the bottom of the pull rod 21, the top of the spring 22 is fixedly connected to the bottom of the fixed plate 14, an activated carbon board 23 is inserted into the top of the pull rod 21, the outer wall of the activated carbon board 23 is slidably connected to the bottom of the inner cavity of the storage box 1, and the rear of the activated carbon board 23 is inserted into the outer wall of the positioning block.

[0029] By pulling the pull rod 21, the spring 22 is stretched so that the outer wall of the pull rod 21 is no longer connected with the inner wall of the activated carbon board 23.

[0030] like Figure 2 , Figure 3 As shown, the left and right parts of the placement plate 31 are slidably connected with a guide block 16, one end of the guide block 16 is fixedly connected to the top of the inner cavity of the storage box 1, the top of the placement plate 31 is fixedly connected with a label 311 in a rectangular array, the left and right parts of the bottom end of the placement plate 31 are fixedly connected with a connecting plate 32, the rear part of the connecting plate 32 is fixedly connected with a limit block 321, and the outer wall of the limit block 321 is slidably connected to the top of the inner cavity of the storage box 1.

[0031] By pulling out the placement plate 31, the placement plate 31 drives the connecting plate 32 to move synchronously, and the connecting plate 32 drives the limiting block 321 to slide on the inner wall of the storage box 1. The limiting block 321 limits the connecting plate 32 to prevent the connecting plate 32 and the placement plate 31 from falling off the inner wall of the storage box 1.

[0032] like Figure 2 , Figure 3 As shown, the bottom end of the connecting plate 32 is fixedly connected to a supporting plate 33, and the left and right parts of the supporting plate 33 are both slidably connected to a guide block 2 17, one end of the guide block 2 17 is fixedly connected to the bottom of the inner cavity of the storage box 1, and the top end of the supporting plate 33 is provided with grooves 34 in a rectangular array, and the grooves 34 are located directly below the through hole.

[0033] When the connecting plate 32 moves, the supporting plate 33 is driven to move synchronously, and the supporting plate 33 slides synchronously on the outer wall of the second guide block 17 .

[0034] like Figure 2-Figure 4 As shown, a second spring 35 is fixedly connected to the inner wall of the placement plate 31, and one end of the second spring 35 is fixedly connected to a clamping plate 36, and the shape of the clamping plate 36 is arc-shaped.

[0035] When the placement plate 31 is pulled out, the reagent tube containing the food test sample can be placed in the placement plate 31, so that the outer wall of the reagent tube contacts the outer wall of the clamping plate 36, and the spring 2 35 contracts. When the bottom end of the reagent tube contacts the inner wall of the groove 34, the next reagent tube can be prevented. At this time, under the action of the spring 2 35, the clamping plate 36 clamps and fixes the reagent tube, thereby clamping and fixing reagent tubes of different diameters, thereby achieving a fixing effect.

[0036] like Figure 2 , Figure 3 , Figure 5As shown, the top of the limit rod 41 is fixedly connected to the limit spring 42, one end of the limit spring 42 is fixedly connected to the fixing plate 43, the bottom of the fixing plate 43 is movably connected to the outer wall of the limit rod 41, the bottom end of the fixing plate 43 is fixedly connected to the front part of the top of the placement plate 31, the outer wall of the limit rod 41 is plugged into the limit plate 44, and the outer wall of the limit plate 44 is plugged into the inner wall of the placement plate 31 and the guide block 16.

[0037] By pulling the limit rod 41, the limit spring 42 is extended so that the outer wall of the limit rod 41 is no longer plugged into the inner wall of the limit plate 44. Then the limit plate 44 can be pulled out so that the outer wall of the limit plate 44 is no longer plugged into the inner wall of the guide block 16 and the placement plate 31, thereby canceling the limit on the placement plate 31.

[0038] The working principle of the utility model is as follows: when in use, the limit rod 41 is pulled to drive the limit spring 42 to extend, so that the outer wall of the limit rod 41 is no longer plugged into the inner wall of the limit plate 44, and then the limit plate 44 can be pulled out, so that the outer wall of the limit plate 44 is no longer plugged into the inner wall of the guide block 16 and the placement plate 31, thereby canceling the limit of the placement plate 31, and then the placement plate 31 can be pulled to make the placement plate 31 slide on the outer wall of the guide block 16, and the placement plate 31 is pulled out, and at the same time, the placement plate 31 drives the connecting plate 32 to move synchronously, so that the connecting plate 31 is The connecting plate 32 drives the supporting plate 33 to move synchronously, and the supporting plate 33 slides synchronously on the outer wall of the guide block 17. At the same time, the connecting plate 32 drives the limiting block 321 to slide on the inner wall of the storage box 1. The limiting block 321 limits the connecting plate 32 to prevent the connecting plate 32 and the placing plate 31 from escaping from the inner wall of the storage box 1. Then, the reagent tube containing the food test sample can be placed in the placing plate 31, so that the outer wall of the reagent tube contacts the outer wall of the clamping plate 36, so that the spring 35 contracts. When the bottom end of the reagent tube contacts the inner wall of the groove 34, the When the next reagent tube is placed, the clamping plate 36 can be used to clamp and fix the reagent tube under the action of the spring 2 35, thereby clamping and fixing reagent tubes of different diameters, thereby achieving a fixing effect. Then, the placement plate 31 can be pushed back into the inner cavity of the storage box 1, and then the placement plate 31 can be limited by the limiting mechanism 4. Then, the box door 12 is closed, and the refrigerator 18 is turned on to cool the inner cavity of the storage box 1 to prevent the food test sample from spoiling. At the same time, the activated carbon plate 23 cools the inner cavity of the storage box 1. The air is purified and the odor in the storage box 1 is absorbed to prevent the odor from affecting the food testing samples. Later, when the activated carbon plate 23 needs to be replaced, the pull rod 21 is pulled to extend the spring 22 so that the outer wall of the pull rod 21 is no longer plugged into the inner wall of the activated carbon plate 23. Then the activated carbon plate 23 can be pulled out so that the outer wall of the activated carbon plate 23 is no longer plugged into the positioning block at the rear end of the inner cavity of the storage box 1. Then the activated carbon plate 23 can be replaced, which makes replacement easier and greatly improves the user experience.
