The inner wall of the top cover of the shell 1 is fixedly connected with a sealing gasket 6, and the sealing gasket 6 is movably connected to the top of the placement shell 3. The sealing gasket 6 is used to seal the sample test tube placed inside the placement shell 3 to avoid shaking when the sample is moved, resulting in sample overflow or cross mixing and affecting the detection data. A support seat 7 is slidably connected to the lower part of the inner wall of the placement cavity at the top of the shell 1. An arc-shaped groove is opened on the top of the support seat 7. The support seat 7 is located below the placement shell 3. The number of support seats 7 is consistent with the placement shell 3 and corresponds to the position of the placement shell 3. The support seat 7 is used to support the bottom of the test tube. A lifting mechanism 8 is provided at the bottom of the support seat 7. The lifting mechanism 8 is used to control the support seat 7 to move up and down, so as to control the up and down movement of the test tube, which is convenient for taking the sample test tube and can make the test tube completely embedded in the interior of the placement shell 3, thereby improving the fixing effect of the test tube and avoiding the test tube from tipping over when the sample is moved. A limiting mechanism 9 is provided on one side of the shell 1. The limiting mechanism 9 is used in conjunction with the lifting mechanism 8. The number of the limiting mechanism 9 is consistent with the lifting mechanism 8. The limiting mechanism 9 is used to In order to limit the parts of the lifting mechanism 8, a movable groove 10 is provided at the bottom of the inner wall of the cavity placed at the top of the shell 1, and the movable groove 10 is located below the support seat 7. The inner wall of the movable groove 10 is slidably connected with a movable block 11, and the movable block 11 is used in conjunction with the movable groove 10 to guide the parts at the top to prevent their position from shifting. Compression springs 12 are fixedly connected to both sides of the bottom of the support seat 7, and guide rods 13 are fixedly connected to the four diagonals of the bottom of the support seat 7. A guide shell 14 is fixedly connected to the bottom of the inner wall of the cavity placed at the top of the shell 1, and the number of guide shells 14 and guide rods 13 are the same and correspond to the position of guide rods 13.

[0023] The lifting mechanism 8 includes fixed plates 81 fixed to both sides of the bottom of the support seat 7. The fixed plates 81 are used in pairs. A limiting groove 82 is provided in the middle of the surface of the fixed plate 81. The middle part of the limiting groove 82 is inclined, and the limiting grooves 82 are symmetrically arranged. A positioning block 83 is fixedly connected to the top of the moving block 11. The limiting rod 92 is located in the middle of the fixed plate 81 and is slidably connected to the fixed plates 81 on both sides. Both sides of the positioning block 83 are fixedly connected with positioning rods 84. The positioning rod 84 is slidably connected to the inner wall of the limiting groove 82. When the test tube needs to be taken out, the limiting rod 84 on one side is moved. The components of the positioning mechanism 9 push the positioning block 83 to drive the positioning rod 84 to slide along the inner wall of the limiting groove 82. When the positioning rod 84 is pushed to the bottom of the lower side of the limiting groove 82, the top of the support seat 7 contacts the bottom of the placement shell 3, and the test tube inside the placement shell 3 is pushed upward to expose the top of the test tube, which is convenient for taking out the sample test tube. Similarly, the components of the limiting mechanism 9 are pulled in the reverse direction to control the positioning rod 84 to move to the higher side of the limiting groove 82, thereby controlling the support seat 7 to move downward, and simultaneously driving the test tube to descend to the inside of the placement shell 3, which is convenient for sealing and storing the sample in the test tube.

The position of the limiting block 93 corresponds to that of the rotating limiting rod 92. The limiting block 93 is L-shaped. By pushing the pull rod 9 The positioning block 83 is controlled to move. When the positioning block 83 drives the positioning rod 84 to move to the side with a lower level of the limiting groove 82, the pull rod 91 is rotated to rotate the limiting rod 92 to the inside of the limiting block 93, so as to limit the positioning block 83 and position the support seat 7 at the bottom of the placement shell 3, which is convenient for placing the test tube. After the placement is completed, the limiting rod 92 is rotated in the opposite direction to release the limit of the positioning block 83, so that the test tube can be driven to move to the inside of the placement shell 3. It is convenient and simple to use and is convenient for taking and placing the sample test tube.

[0025] Working principle: first push the pull rod 91 inward, control the positioning block 83 to drive the positioning rod 84 to slide along the inner wall of the limiting groove 82 to the side of the limiting groove 82 with a lower level, and drive the fixing plate 81 to lift the support seat 7 upward by sliding the positioning rod 84 inside the limiting groove 82, so that the top of the support seat 7 fits with the bottom of the placement shell 3, then rotate the pull rod 91, rotate the limiting rod 92 to the inside of the limiting block 93, so as to limit the positioning block 83, so that the support seat 7 keeps fitting with the bottom of the placement shell 3 during the placement process, operate multiple lifting mechanisms 8 and limiting mechanisms 9 in sequence, and then place the sample test tubes in sequence. It is placed inside the placement shell 3 and can be placed in different areas according to the characteristics of the samples. The risk of test tube damage can be reduced by protecting it with the protective pad 4. After placement is completed, the sample information in the test tube can be marked on the groove on the top of the placement shell 3, and then the limit rod 92 is rotated in the opposite direction to disengage it from the inside of the limit block 93 to release the limit on the positioning block 83, and then the pull rod 91 is slowly pulled outward to control the positioning rod 84 to move to the side with a higher level of the limit groove 82, so as to control the support seat 7 to move downward, so that the test tube on the top of the support seat 7 moves downward synchronously and is completely embedded in the interior of the placement shell 3, and then the top cover of the shell 1 can be closed.
