[0053] According to the requirements, the height increasing column 12 can be designed in multiple sizes to adapt to sample tubes 3 of different heights. When the height of the sample tube 3 is smaller than the depth of the pipe groove 2, appropriate height increasing column 12 and height increasing seat 11 are selected, and then the sample tube 3 is placed in the pipe groove 2. This structure is suitable for sample tubes 3 of multiple specifications and heights, and is convenient, flexible, and widely applicable.
[0054] As shown in Figure 1 , the sample bin includes a box body 14 with an open upper end and a front end, a first horizontal plate 15 arranged above the front end of the box body 14, a first partition plate 16 fixed at the lower end of the first horizontal plate 15, a second horizontal plate 17 arranged above the rear end of the box body 14, and a second partition plate 18 arranged on the inner wall of the bottom of the box body 14 and corresponding to the second horizontal plate 17. The first partition plate 16 corresponds to the second partition plate 18.
[0055] The first horizontal plate 15 and the second horizontal plate 17 can improve the strength of the sample bin. When the sample rack 1 is placed in the sample bin, the first partition plate 16 can guide the inserted sample rack 1, and after being placed, the second partition plate 18 can further guide the sample rack 1, so that the operation of placing the sample rack 1 in the sample bin is more convenient.
[0056] As shown in Figure 1 and Figure 6As shown, the device further comprises a guide seat 19 arranged at the lower end of the second horizontal plate 17, a guide slot 20 arranged at the lower end of the guide seat 19, and a guide plate 21 arranged at the inner end of the sample holder 1, one end of the guide plate 21 being fixed to the inner end of the sample holder 1, the other end horizontally overhanging and corresponding to the guide slot 20.
[0057] When the sample holder 1 is inserted into the sample chamber, the guide plate 21 and the guide slot 20 cooperate to further guide and position the sample holder 1, and the operation is more convenient.
[0058] As shown in Figure 1 , Figure 6 and Figure 8 , a self-locking mechanism is arranged in the sample chamber, which comprises a self-locking seat 22 arranged in the sample chamber, a sliding groove 23 arranged at one end of the self-locking seat 22 towards the sample holder 1, a sliding block 24 slidingly arranged in the sliding groove 23, a self-locking hook 25 arranged on one side of the sliding block 24, a return spring 26 arranged between the inner end of the sliding block 24 and the bottom of the sliding groove 23, a self-locking guide slot 27 arranged on the side wall of the sliding groove 23, a C-shaped spring piece 28 arranged at the outer end of the sliding block 24, and a locking head 29 arranged at the inner end of the sample holder 1, the self-locking seat 22 corresponding to the inner end of the sample holder 1, the self-locking guide slot 27 corresponding to the self-locking hook 25, and the bent end of the self-locking hook 25 extending into the self-locking guide slot 27, the opening end of the C-shaped spring piece 28 corresponding to the locking head 29.
[0059] The return spring 26 presses the sliding block 24, so that the C-shaped spring piece 28 remains in the state of being outside the sliding groove 23. When the sample holder 1 is put into the sample chamber, the locking head 29 on the inner end of the sample holder 1 is inserted into the opening of the C-shaped spring piece 28, and with the continuous insertion of the sample holder 1, the sliding block 24 is pushed to slide into the sliding groove 23. At this time, the bent end of the self-locking hook 25 slides into the self-locking guide slot 27. After the sample holder 1 is in place, the C-shaped spring piece 28 enters the sliding groove 23, and the C-shaped spring piece 28 in the open state is limited by the sliding groove 23, and becomes in the closed state, tightly holding the locking head 29, and the self-locking hook 25 is hooked in the self-locking guide slot 27, achieving locking. When the sample holder 1 is pushed inwards again, the self-locking hook 25 slides out of the self-locking guide slot 27, and the sliding block 24 slides outwards under the action of the return spring 26, until the C-shaped spring piece 28 slides out of the sliding groove 27, changing from the closed state to the open state, releasing the locking head 29 and disengaging from the locking head 29, so that the sample holder 1 can be taken out. The design can be self-locked after the sample holder 1 is put into the sample chamber, is convenient to use, and has low cost. The specific structure of the self-locking guide slot 27 is shown in Figure 5 .
[0060] As shown in Figure 1 , Figure 6 and Figure 8As shown, the C-shaped elastic sheet 28 is inwardly bent at the opening end to form a barb. The locking strength of the locking head 29 can be further improved, effectively avoiding the problem that the locking head 29 may be separated from the C-shaped elastic sheet 28 after the sample rack 1 is stressed.
