Specific implementation mode
It is described further below in conjunction with the accompanying drawings：
A kind of measured hole adjustable x-ray fluorescence analysis dress test sample, mainly puts by sample holder 1, set on sample
It sets the end cap 2 of 4 upper end of box, the peephole 1 on end cap 2, the spring backing plate 4 in sample holder 1, placed on spring backing plate 4
Spring 5, the sample backing plate 6 placed on spring 5 form, have cyclic annular convex block 8 in the lower face overall processing of end cap 2, in ring
The lower end of shape convex block 8 is connected with measured hole adjuster 7, and measured hole adjuster 7 is connected by screw thread and sample holder 1.
The measured hole adjuster 7 is interior using whole or welding by card slot 10, the shell 9 that shell 9,9 top of shell process
