[0031] Reference Figure 1 , Figure 3 and Figure 4The moving block 4 is clamped with a connecting plate 11, and the inner walls of the connecting plate 11 are in contact with an upper glass slide 12 and a lower glass slide 13 respectively. The upper glass slide 12 and the lower glass slide 13 are made of transparent glass materials, so that the test sample can be placed between the upper glass slide 12 and the lower glass slide 13, so that the test sample can be subsequently scanned. The bottom end of the upper glass slide 12 is fixedly connected with a cannula 14, so that the upper glass slide 12 and the lower glass slide 13 can be quickly spliced ​​together, and can also be moved at the same time. The outer walls of the upper glass slide 12 and the lower glass slide 13 are respectively fixedly connected with a square frame 15, and the upper portion of the connecting plate 11 has a notch for sliding the square frame 15. The inner wall of the left end of the square frame 15 is elastically connected with a wedge 17 through a positioning spring 16. The wedge 17 is inclined, and when squeezed, the wedge 17 will be Sliding on the inner wall of the square frame 15, the cannula 14 is plugged into the inner wall of the lower glass slide 13, the upper glass slide 12 is in contact with the lower glass slide 13, the square frame 15 is slidably connected to the inner wall of the connecting plate 11, and the inner wall of the left end of the square frame 15 is fixedly connected to one end of the positioning spring 16. When the wedge block 17 moves to the left, the positioning spring 16 will be compressed. When resetting, the elastic force of the positioning spring 16 is used to reset the wedge block 17. The other end of the positioning spring 16 is fixedly connected to the left end of the wedge block 17. The wedge block 17 is plugged into the inner wall of the connecting plate 11. A plurality of slots for plugging with the wedge block 17 are provided on the connecting plate 11, so that the wedge block 17 can be plugged with it to position the upper glass slide 12 and the lower glass slide 13. It is necessary to use manual force to move it to squeeze the wedge block 17.

[0032] Reference Figure 1-Figure 2 The top of the moving block 4 is fixedly connected to one end of the return spring 5. When the limit block 6 moves upward, the return spring 5 will be stretched. When resetting, the return spring 5 is used to bring the limit block 6 back to normal. The other end of the return spring 5 is fixedly connected to the inner side wall of the limit block 6. The limit block 6 penetrates and is slidably connected to the inner wall of the moving block 4. The limit block 6 is plugged into the top of the slide rack 1. The slide rack 1 is provided with multiple groups of notches corresponding to the limit block 6. The shielding mechanism includes a shielding plate 10, which is fixedly connected to the outer wall of the fixed plate 2. The shielding plate 10 is in contact with the connecting plate 11. The shielding plate 10 can shield the connecting plate 11 to prevent the connecting plate 11 from moving out of the slide rack 1.

[0033] Working principle: First, when the upper glass slide 12 deviates from the scanning point to a certain extent, it is only necessary to move the upper glass slide 12 and the lower glass slide 13 horizontally, so that the inner wall notch of the connecting plate 11 presses the inclined surface of the wedge block 17, so that the wedge block 17 moves to the left and compresses the positioning spring 16. When the wedge block 17 coincides with the inner wall notch of the next connecting plate 11, the reverse elastic force of the positioning spring 16 is used to reset the wedge block 17, so that the wedge block 17 is plugged into the inner wall notch of the connecting plate 11, and the position adjustment of the entire upper glass slide 12 is completed. The upper glass slide 12 can be adjusted according to actual conditions.

[0034] When it is necessary to take the connecting plate 11 out of the glass slide rack 1, you only need to move the connecting plate 11 to the left from the right and continue to compress the spring plate 9 to separate the right end of the connecting plate 11 from the opening of the moving block 4 and the glass slide rack 1, and then move the connecting plate 11 out of the glass slide rack 1 in an inclined state. At the same time, the spring plate 9 can be reset by its own elastic force when it is not squeezed. When it is necessary to install the connecting plate 11, you only need to insert the left end of the connecting plate 11 between the supporting plate 7, the positioning plate 8 and the shielding plate 10, so that the left end of the connecting plate 11 contacts and squeezes the spring plate 9, and then place the right end of the connecting plate 11 at the opening of the moving block 4 and the glass slide rack 1 in an inclined state. Then release the connecting plate 11 and use the reverse elastic force of the spring plate 9 to push the connecting plate 11 to the right, so that the right end of the connecting plate 11 is stuck in the opening of the glass slide rack 1 and the moving block 4, thereby completing the entire disassembly and assembly process of the connecting plate 11.

[0035] When it is necessary to adjust the width of the connecting plates 11 of different diameters, it is only necessary to move the limit block 6 upwards and compress the reset spring 5. Then, the limit block 6 is moved to move the moving block 4 and the partition plate 3. According to the actual situation, the distance between the partition plates 3 is increased to adapt to connecting plates 11 of different widths. When limiting, it is only necessary to loosen the limit block 6 and use the reverse elastic force of the reset spring 5 to reset the limit block 6, so that the limit block 6 and the top notch of the slide rack 1 are plugged into each other to limit the entire moving block 4 and the partition plate 3.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
