Embodiment

In order to technology feature of the present utility model, object and effect are had understanding clearly, now compare accompanying drawing and embodiment of the present utility model be described:

Fig. 1 is side-view of the present utility model; Fig. 2 is vertical view of the present utility model; Fig. 3 is upward view of the present utility model; Fig. 4 is the sectional view of line A-A along Fig. 1; Fig. 5 is the partial enlargement figure at H place in Fig. 4.

See Fig. 1 to Fig. 3, device held by the x-ray diffraction experiment sample that the utility model proposes dress, and it comprises supporting table 2 in an outer sleeve 1 and, described interior supporting table 2 can movement be placed in described outer sleeve 1, its upper surface is placed with a load sample platform 3. Wherein, described outer sleeve 1 and interior supporting table 2 are preferably Stainless Steel processing, and described load sample platform 3 is adopted and is made of resin. In actual applications, can be placed with two-sided glue etc. by testing sample is fixed on described load sample platform 3, subsequently, described interior supporting table 2 is moved in described outer sleeve 1, till the upper surface of testing sample upper surface and described outer sleeve 1 is positioned in same plane, then the utility model is fixed in the sample table of X-ray diffractometer, make the upper surface of described outer sleeve and the upper surface flush of sample table, the program of reruning carries out X ray test, finally surveyed data are carried out analyzing and processing, the information such as institute's test sample product crystalline structure can be obtained.

Such as Fig. 4, the inwall of described outer sleeve 1 is provided with box thread 11, and described interior supporting table 2 is cylindrical, and its outer side is formed with male thread 21, and described male thread 21 spiral shell corresponding to described box thread 11 connects. Thus, by rotating described interior supporting table 2, can move relative to described outer sleeve 1, thus regulate its position in described outer sleeve 1, to control the height of testing sample, ensure that the upper surface of testing sample and sample table is in a plane.

In order to improve the stability of rotation, avoid that the situations such as slide fastener occur, it is preferable that described male thread 21 and described box thread 11 are square thread.
