[0040] When in use, the sample can be placed in the sample slot 3, and then the storage box 2 can be placed in the frame 1. The storage box 2 can be installed by insertion. After installation, the docking block 6 and the docking slot 8 are connected and locked with the locking mechanism. When the sample is taken later, the storage box 2 can also be pulled out to avoid adjacent samples being too close to affect the taking. The number of storage boxes 2 installed can also be selected according to the needs of use, which is more flexible to use. Example 2
[0041] On the basis of the first embodiment, a locking mechanism is disclosed, which includes a locking groove 7, a locking block 9, a first spring 10, a connecting rod 11, a transmission plate 12 and a control rod 13. The locking groove 7 is provided on the lower surface of the docking block 6. The locking block 9 is arranged inside the docking groove 8 and engages with the locking groove 7. The first spring 10 is arranged below the locking block 9 to provide an upward thrust for the locking block 9. The connecting rod 11 is fixed below the locking block 9. The transmission plate 12 is fixed below the connecting rod 11, and an up-and-down sliding structure is formed between the transmission plate 12 and the frame 1. The control rod 13 is fixed above the transmission plate 12, and the upper end of the control rod 13 passes through the upper surface of the frame 1. The front side of the locking block 9 is designed with an inclined structure, and can move when squeezed.
[0042] After the docking block 6 enters the docking groove 8, the locking block 9 is connected to the locking groove 7 under the action of the first spring 10, and the connection between the docking block 6 and the docking groove 8 is locked, so that the storage box 2 remains stable on the frame 1. When it is necessary to release the connection between the locking block 9 and the locking groove 7 later, the control rod 13 can be pressed, and the control rod 13 pushes the transmission plate 12 downward to move. The transmission plate 12 drives the locking block 9 to move through the connecting rod 11, and the connection between the locking block 9 and the locking groove 7 is released, so that the docking block 6 can be taken out from the docking groove 8. Example 3
[0043] On the basis of the first embodiment, an external pulling mechanism is disclosed, which includes a first magnet 16, a second magnet 17, a movable plate 18, a third spring 19, a groove 20 and a fixed block 21. The first magnet 16 is fixed to the outer end of the pressure plate 14, and a sliding connection is formed between the first magnet 16 and the storage box 2. The second magnet 17 is arranged on the outer side of the first magnet 16, and the second magnet 17 and the first magnet 16 are opposite poles. The movable plate 18 is fixed on the outer side of the second magnet 17 to control the movement of the second magnet 17, and a front-to-back sliding structure is formed between the movable plate 18 and the storage box 2. The third spring 19 is arranged on the front side of the movable plate 18 to provide thrust for the movable plate 18. The groove 20 is opened at the rear end of the movable plate 18, and the rear side of the groove 20 is opened. The fixed block 21 is fixed on the inner side of the frame 1, and a concave-convex matching structure is formed between the fixed block 21 and the groove 20. The attraction between the first magnet 16 and the second magnet 17 is greater than the elastic force of the second spring 15.
[0044] When the storage box 2 is not installed on the frame 1, the movable plate 18 drives the second magnet 17 to move to a relative position with the first magnet 16 under the action of the third spring 19, and attracts the pressure plate 14 to move. At this time, the pressure plate 14 does not produce a limiting effect, which is convenient for taking and placing samples. When the storage box 2 is installed on the frame 1, the fixed block 21 is connected to the groove 20, pushing the movable plate 18 to move, so that the position of the second magnet 17 and the position of the first magnet 16 are staggered. At this time, the pressure plate 14 will move under the action of the second spring 15, and limit the sample in the sample slot to keep it stable. The limit is automatically released when the storage box 2 is removed later, which is convenient to use.
