[0030] Specifically, the expansion and contraction of the spring 5 can make the guide block 6 slide left and right along the guide rail 4. When the guide block 6 moves, it can drive the rotating plate 7 to rotate, thereby causing the U-shaped block 8 and the mounting plate 9 thereon to move up and down. By rotating the threaded rod 11 on the positioning plate 10, the fixed plate 12 can also move forward and backward.

[0031] Reference Figure 1 and Figure 2 The fixed structure 2 includes two positioning covers 201, which are respectively fixedly connected to the left and right sides of the bottom of the table 1. A lifting plate 203 is provided at the bottom of the positioning cover 201. Grooves 204 are provided at the front and rear sides of the top of the lifting plate 203. An electric telescopic rod 202 is fixedly connected to the inner side of the groove 204. The tops of the two electric telescopic rods 202 are respectively fixedly connected to the front and rear sides of the top of the inner wall of the positioning cover 201. A support plate 205 is fixedly connected to the outer side of the lifting plate 203.

[0032] Specifically, starting the electric telescopic rod 202 can move the lifting plate 203 up and down along the inner side of the positioning cover 201. The moving lifting plate 203 can support the device through the support plate 205 at the bottom thereof, thereby stably supporting and adjusting the height position of the device.

[0033] Reference Figure 1 and Figure 2 The right side of the right positioning cover 201 is fixedly connected with a controller 13, and the controller 13 is electrically connected to the electric telescopic rod 202; the outer side of the controller 13 is fixedly connected with a housing 14, and the outer side of the housing 14 is rotatably connected with a shield 15; the left and right sides of the bottom of the inner wall of the two connecting plates 3 are provided with sliding grooves 22, and the bottoms of the multiple guide blocks 6 are respectively slidably connected with the corresponding sliding grooves 22;

[0037] Working principle: Before using the device, first, the extension and retraction of the spring 5 drives the guide block 6 to slide left and right along the guide rail 4. The movement of the guide block 6 triggers the rotation of the rotating plate 7, and the rotation of the rotating plate 7 prompts the U-shaped block 8 and the mounting plate 9 thereon to move up and down. At the same time, by rotating the threaded rod 11 on the positioning plate 10, the fixed plate 12 can also move forward and backward. This design can clamp and maintain the balance of objects of different sizes to more effectively perform resonance analysis, thereby improving the reliability of the device, and by starting the electric telescopic rod 202, the lifting plate 203 moves up and down along the inner side of the positioning cover 201.
