[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-2 A sample holder for an infrared spectroscopy detection device includes an upper clamping plate 1 and a lower clamping plate 2 stacked on top of each other. The upper clamping plate 1 and the lower clamping plate 2 are made of aluminum. A window 3 is opened in the middle of the upper clamping plate 1 and the lower clamping plate 2. A limiting groove 4 is provided on the opposite side of the upper clamping plate 1 and the lower clamping plate 2. The limiting groove 4 is located outside the window 3. An anti-slip layer is provided on the inner wall of the limiting groove 4. The anti-slip layer increases the friction and prevents the sample from slipping or falling off during the clamping process. Four sets of mutually symmetrical limiting holes 5 are opened on the upper clamping plate 1 and the lower clamping plate 2 outside the limiting groove 4. A power component for clamping the upper clamping plate 1 and the lower clamping plate 2 is provided at the limiting hole 5 on the lower clamping plate 2. Example 1:

[0020] Please see Figures 1-2 The power component includes a limiting rod 6 that is slidably inserted into the limiting hole 5. Both ends of the limiting rod 6 are fixedly equipped with baffles 7. Both ends of the baffles 7 are fitted with compression springs 8. The other side of the compression springs 8 is fixedly equipped with a movable ring 9, which is fitted on the outside of the limiting rod 6. The compression springs 8 will cause the upper clamping plates 1 and the lower clamping plates 2 on both sides to tend to move closer to each other, thereby achieving a clamping effect. Example 2:

[0021] Please see Figure 3 The power component includes a second limiting rod 10 that slides into the limiting hole 5. The lower clamping plate 2 has grooves at its four corners, and a strong magnet 11 is embedded in the grooves. A second strong magnet 12 is glued to the four corners of the upper clamping plate 1 corresponding to the first strong magnet 11. By connecting the upper clamping plate 1 and the lower clamping plate 2 together, the second strong magnet 12 and the first strong magnet 11 can attract each other, thereby enabling a clamping force between the upper clamping plate 1 and the lower clamping plate 2. Example 3:

[0022] Please see Figure 4 The power component includes a limiting rod 6 that slides into the limiting hole 5. Baffles 7 are fixedly installed at both ends of the limiting rod 6. Compression springs 8 are sleeved on the outer sides of both ends of the baffles 7. A movable ring 9 is fixedly installed on the other side of the compression spring 8, and the movable ring 9 is sleeved on the outer side of the limiting rod 6. Grooves are provided at the four corners of the lower clamping plate 2, and strong magnets 11 are embedded in the grooves. Strong magnets 12 are glued to the four corners of the upper clamping plate 1 corresponding to the strong magnets 11. The elastic force of the compression spring 8 causes the upper clamping plate 1 and the lower clamping plate 2 on both sides to tend to move closer to each other. Furthermore, the mutual attraction between the strong magnets 12 and 11 further increases the clamping force between the upper clamping plate 1 and the lower clamping plate 2, thus enabling stable clamping.

[0023] In summary, the sample clamp of this infrared spectroscopy detection device, through the elastic force of the compression spring 8, causes the upper clamping plate 1 and the lower clamping plate 2 on both sides to tend to move closer to each other. Furthermore, the strong magnets 12 and 11, which attract each other, further enhance the clamping force between the upper clamping plate 1 and the lower clamping plate 2, thereby enabling stable clamping. This allows it to replace the bolt-type clamping method, making it convenient and quick.
