[0023] The stabilizing mechanism 2 includes a fixing nut 201, a telescopic screw 202, a fixing block 203 and a cushion block 204. Four fixing blocks 203 are installed at the bottom of the four frames 4, and four fixing nuts 201 are symmetrically installed at the four corners of the top of the four fixing blocks 203. The centers of the four fixing nuts 201 are fixedly connected with four telescopic screws 202 by threads, and four cushion blocks 204 are installed at the bottom of the four telescopic screws 202. Four suction cups 15 are installed at the centers of the bottoms of the four fixing blocks 203, which is beneficial for supporting the equipment through the cushion blocks 204 in the stabilizing mechanism 2, increasing the contact area between the equipment and the ground, and improving the stability of the equipment installation.

[0024] Working principle: During use of the utility model, the support plate 1 is first installed on the frame 4, and the suction cup 15 at the bottom of the frame 4 is adsorbed and installed on the exciting platform. At the same time, the telescopic screw 202 in the stabilizing mechanism 2 is rotated. Since the telescopic screw 202 is fixedly connected to the fixing nut 201 by threads, the telescopic screw 202 is driven to move downward, and then the cushion block 204 is driven to move downward, and the cushion block 204 is used to fit with the top of the exciting platform, thereby expanding the contact area of ​​the device with the exciting platform, which is beneficial to improving the installation stability of the device. After installation, ensure that the limiting hole 14 on the support plate 1 is aligned with the exciting electrode on the exciting platform, and then place the test sample with the test surface facing up on the top center of the support plate 1, and then put the positioning plate 6 on the frame 4, and then adjust the position of the test sample to ensure that the test point on the top of the test sample is aligned with the central fixing hole 5 on the positioning plate 6. At this time, the positioning plate 6 is used to press and fix the test sample, and then the first handle 9 is twisted. , since the first handle 9 and the second threaded block 10 are connected by threaded fixing, the first handle 9 is pressed and fixed to the frame 4 on one side, ensuring the pressing and fixing of the positioning plate 6 and the test sample. Then, hold the connecting plate 18, use the top of the marker 17 to pass through the limiting hole 14, mark the bottom of the test sample, and align the marking point with the point to be tested. After marking, rotate the first handle 9 in the opposite direction, move the positioning plate 6 upward, remove the sample to be tested, place the test surface of the test sample on the excitation electrode, and then install the probe 16 on the central fixing hole 5 to ensure that the bottom of the probe 16 passes through the bottom of the limiting hole 14 and that the bottom of the probe 16 faces the excitation electrode. At this time, adjust the sample to be tested to ensure that the marking point coincides with the probe 16, that is, the point to be tested faces the excitation electrode, thereby completing the positioning of the sample to be tested. The screw 8 is used to install the side bracket 7, the second movable sleeve 13 is used to install the first threaded block 3, and the first threaded block 3 is used to install the second handle 12.
