[0023] In this embodiment, Figure 2 As shown, the second threaded rod 502 and the limiting column 504 are parallel to each other, and the top end of the second threaded rod 502 is rotatably connected to the top of the gantry 4, the second threaded rod 502 is threadedly connected to the lifting frame 503, the upper and lower ends of the limiting column 504 are respectively fixedly connected to the top of the gantry 4 and the top of the sample table 1, the bottom surface of the lifting frame 503 is fixedly connected to the top of the protective outer panel 6, and the protective outer panel 6 is a U-shaped structure; the lifting frame 503 can be lifted vertically, thereby driving the protective outer panel 6 to lift and lower, and when the lifting frame 503 moves downward, the protective outer panel 6 and the protective outer panel 6 also move downward synchronously, surrounding the sample to be tested in the middle to prevent debris generated by the test from splashing out and injuring people.

[0025] The use method and advantages of the utility model: When the sample fixture capable of stable anti-deviating is used, the working process is as follows:
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the sample to be tested is placed on the sample table 1, and then the motor 301 is started to drive the first threaded rod 302 to rotate. When the first threaded rod 302 rotates, it will drive the two moving blocks 304 to move in opposite directions. At this time, the two moving blocks 304 are close to each other and drive the clamping plate 305 on the top to clamp and fix the left and right sides of the sample. When the first threaded rod 302 rotates, it will synchronously drive the main bevel gear 303 to rotate, and the main bevel gear 303 will drive the secondary bevel gear 501 to rotate, and the secondary bevel gear 501 will drive the second threaded rod 502 to rotate. The second threaded rod 502 is threadedly connected to the lifting frame 503, so the lifting frame 503 can move downward, thereby driving the two pressing plates 505 in the middle and the protective outer plate 6 at the bottom to move downward synchronously. When the protective outer plate 6 moves downward, it will synchronously drive the protective inner plate 7 to move downward. If the sample is small, the bottom of the protective inner plate 7 will be aligned with the bottom of the protective inner plate 7. When the top surface of the sample stage 1 is in contact with the inner protective plate 7, the top of the protective inner plate 7 will be received inside the protective outer plate 6, so that the protective outer plate 6 and the protective outer plate 6 can block the sample stage 1 to prevent the debris generated during the sample detection from splashing and injuring people. The two pressure plates 505 are fixed in the middle of the lifting frame 503, so they will also rise and fall with the lifting frame 503, and at the same time drive the moving bar 506 between the two pressure plates 505 to move downward, and the telescopic rods 507 at the bottom of both ends of the moving bar 506 will contact the top surface of the sample stage 1. When the pressure plate 505 is in contact with the top of the sample, turning the knob 509 drives the third threaded rod 508 to rotate, driving the two moving bars 506 to approach each other, thereby driving the telescopic rod 507 at the bottom to clamp and fix the front and back sides of the sample. This structure can fix the front, back, left, right and top of the sample at the same time, with a good clamping effect, which prevents the sample from shifting during the detection process and affecting the detection results.
