[0022] In the description of the utility model, it should be noted that, unless otherwise specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected;It can be mechanically connected, or it can be electrically connected;It can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. Example one:

[0023] The X fluorescence spectrometer with protection net provided by the utility model is preferably implemented as follows Figures 1 to 4FIG. 1 shows an X-ray fluorescence spectrometer with a protective net, comprising a spectrometer body 1 and a fixed protective frame 4.

[0024] The fixing mechanism 7 includes a clamping strip 702, a telescopic rod 701 is fixedly installed on the outside of the clamping strip 702, a contraction groove 703 is provided on the inner wall of the fixed protective frame 4, the telescopic rod 701 is inserted into the contraction groove 703, a spring 706 is fixedly connected between one end of the telescopic rod 701 and the inner wall of the contraction groove 703, a pull rod 707 is fixedly installed on the top of the telescopic rod 701, a slide groove 708 is provided between the top of the fixed protective frame 4 and the contraction groove 703, and the pull rod 707 moves through the slide groove 708.

[0025] Specifically, the above technical solution is that when the X-ray fluorescence spectrometer with the protective net 6 is in use, the fixed protective frame 4 can be installed above the test window 9 by tightening the screws, so that the protective net 6 is stuck in the test window 9 to protect the test window 9. When the sample needs to be tested, the pull rod 707 can be pulled outward, and the pull rod 707 drives the telescopic rod 701 to retract into the retraction groove 703, so that the telescopic rod 701 compresses the spring 706, and then the sample is placed in the fixed protective frame 4. At this time, the pull rod 707 is released, and the telescopic rod 701 will drive the clamping strip 702 to retract the sample under the reset force of the spring 706.
