[0027] The present invention will be further described below with reference to the accompanying drawings and examples.

[0028] like Figure 1 As shown, this embodiment proposes a bidirectional adjustment clamping mechanism, including a clamping table fixing block 05 and a sample clamping table 1, wherein the clamping table fixing block 05;

[0029] The sample clamping platform 1 is an L-shaped structure for clamping the sample. The sample clamping platform 1 includes: a U-shaped platform connector 04, a right table 010 and a left table 011. Figure 2 As shown, the U-shaped platform connector 04 includes a U-shaped bottom 001 and two bifurcated ends 002. The two bifurcated end surfaces of the U-shaped connector are respectively perpendicularly connected to the right table top 010 and the left table top 011. The right table top 010 and the left table top 011 are located in the same plane and on the same side of the U-shaped platform connector 04. The U-shaped connector is perpendicular to the right table top and the left table top, thereby forming an L-shaped structure.

[0030] The right table top 010 and the left table top 010 are respectively provided with a spring column 01 and a spring clip 02 .

[0031] like Figure 3 As shown, the spring clip 02 includes three bent parts, namely the spring column fixing portion 007, the bent connecting portion 008, and the clamping portion 009. The spring column fixing portion is parallel to the clamping portion, and the spring column fixing portion is connected to the clamping portion through the bent connecting portion.

[0032] A through hole 005 is provided on the spring column fixing part, and threaded fixing holes are also provided on the right table 010 and the left table 011 respectively. The spring column fixing part is installed on the right table 010 and the left table 011 through the spring column, and the clamping part is tightly attached to the table for clamping the sample.

[0033] Optionally, the left table top 011 is wider than the right table top 011, and the left table top has a widened edge 006 for embedding into the groove.

[0034] When clamping, you can manually open the left and right spring clips 02 and place the noise suppression sheet 09 on the right table 010 and the left table 011 in turn. At this time, the spring clips 02 apply downward pressure to clamp the noise suppression sheet 09. Figure 1 The figure shows a schematic diagram of the noise suppression sheet (NSS) loading. The noise suppression sheet 09 is clamped and fixed on the sample clamp by opening and closing the spring clamp 02 on the sample clamp 1.

[0035] Figure 4 As shown, the clamping table fixing block 05 includes a fixing body, a cross groove, and a knob, wherein the cross groove is formed on the fixing body, and has a horizontal groove 003 and a vertical groove 004 respectively, and the groove is for the left table 011 to be embedded. After the left table 011 is embedded, tighten the vertical fixing knob 06 or the horizontal fixing knob 08 to fix the sample clamping table 1.

[0036] like Figure 5 As shown, if the sample needs to be kept horizontal, the left table surface 011 is embedded in the horizontal groove 003 of the clamping table fixing block 05. The clamping table fixing block 05 is vertically connected to the sample Z-axis precision fine-tuning slide 07. The Z-axis slide is mechanically connected to the Y-axis precision fine-tuning slide 03 through the support column 012 and fixed to the base plate.

[0037] like Figure 6 As shown, if the sample needs to be kept in a vertical direction, the left table 011 is embedded in the vertical groove 004 of the clamping table fixing block 05, so that the sample can be placed in a vertical direction. It can be seen that the device of the utility model can conveniently adjust the direction of the sample clamping and is easy to operate.
