[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the utility model.

[0031] REFERENCE Figure 1 and Figure 2This utility model provides an embodiment of a small-sized sample device suitable for an X-ray diffractometer, comprising a square plate 1, which provides support for the sliding of a slider 13. A slider 13 is slidably connected through the upper inner wall of the square plate 1. The slider 13 is secured to the inner wall of a limiting groove 3 by a clamping plate 2 to fix its position. When the clamping plate 2 leaves the inner wall of the limiting groove 3, the slider 13 can slide. A sliding groove 12 is provided on the inner wall of the front end of the slider 13, providing guidance for its sliding. A limiting groove 3 is formed on the inner wall of the right end of the slider 13, and multiple limiting grooves 3 are provided. A threaded connection is provided through the inner wall of the bottom end of the slider 13. The fastening bolt 7 rotates to adjust the height of the bearing plate 5. The bearing plate 5 is threadedly connected to the upper inner wall of the fastening bolt 7. The bearing plate 5 provides support for the rotation of the rotating plate 8. The bearing plate 5 has a screw hole 14 on the lower inner wall. The screw hole 14 facilitates the installation of the bearing plate 5 on the fastening bolt 7. The upper inner wall of the bearing plate 5 is equipped with a rotating component for adjusting the sample position. The left outer wall of the square plate 1 is fixedly connected to a fixing plate 6. The left outer wall of the fixing plate 6 can be placed in the MPD sample holder for clamping. The fixing plate 6 is L-shaped. The upper inner wall of the square plate 1 is equipped with a limit component for limiting the slider 13.

[0032] Reference Figure 2 and Figure 4 The rotating assembly includes a rotating plate 8. The upper outer wall of the rotating plate 8 is used to place the sample to be tested. The rotating plate 8 rotates by the rotation of the gear 11. The bottom inner wall of the rotating plate 8 is provided with teeth, which mesh with the gear 11. The outer wall of the rotating plate 8 is rotatably connected to the upper inner wall of the support plate 5. An operating rod 4 is rotatably connected to the bottom inner wall of the support plate 5. The rotation of the operating rod 4 can drive the gear 11 to rotate. The gear 11 is fixedly connected to the upper outer wall of the operating rod 4. The gear 11 drives the rotating plate 8 to rotate by the rotation of the operating rod 4.

[0033] Reference Figure 3 The limiting component includes a fixing ring 9. The outer wall of the fixing ring 9 is slidably connected to the inner wall of the square plate 1. The outer wall of the right end of the fixing ring 9 is elastically connected to the inner wall of the square plate 1 through a spring 10. One end of the spring 10 is fixedly connected to the inner wall of the square plate 1, and the other end of the spring 10 is fixedly connected to the outer wall of the right end of the fixing ring 9. A clamping plate 2 is fixedly connected to the inner wall of the fixing ring 9. When the clamping plate 2 moves to the right, it causes the fixing ring 9 to move synchronously and compress the spring 10. When the external force on the clamping plate 2 is removed, the elastic force of the spring 10 causes the clamping plate 2 to move to the left through the fixing ring 9. The outer wall of the clamping plate 2 is slidably connected to the inner wall of the square plate 1, and the outer wall of the left end of the clamping plate 2 is engaged with the inner wall of the limiting groove 3.

[0034] Working principle: The left side of the fixing plate 6 is fixed in the MPD sample holder. The sample to be tested is then placed in the center area on the upper side of the rotating plate 8. The fastening bolt 7 is rotated to adjust the vertical position of the bearing plate 5 and the rotating plate 8 so that the upper surface of the sample is at the same height as the upper outer wall of the fixing plate 6. XRD experiments can then be performed. When it is necessary to change the direction of the sample to be tested, the operating lever 4 is rotated. The operating lever 4 drives the rotation of the gear 11, which in turn rotates the rotating plate 8 to adjust the direction of the sample to be tested at the upper end. After the test is completed, the limiting of the slider 13 is released by moving the clamping plate 2, and the slider 13 can be moved downward to facilitate the quick removal of the sample. After removal, a new sample to be tested can be placed on the rotating plate 8. The slider 13 is then moved upward and fixed by the clamping plate 2. Finally, by rotating the fastening bolt 7 a few times, the surface of the sample to be tested can be made at the same height as the upper outer wall of the fixing plate 6.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
