Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The main structure of this embodiment includes: tooling assembly and connecting assembly;
[0029] The tooling assembly is used to cooperate with the connecting assembly to complete the test. Specifically, the tooling assembly includes a hexahedron 11, a quartz accelerometer adapter plate 12 and a suspension wire accelerometer adapter plate 13 set on the hexahedron 11; the connecting assembly includes a first protrusion 21 fixed to the bottom surface of the quartz accelerometer adapter plate 12, a first threaded hole 22 opened on the surface of the first protrusion 21, a second protrusion 23 fixed to the bottom surface of the suspension wire accelerometer adapter plate 13, a second threaded hole 24 opened on the surface of the second protrusion 23, a square plate 25 fixed to the top surface of the hexahedron 11, and a third threaded hole 26 opened on the surface of the square plate 25;
[0030] In practical use, the first protrusion 21 and the square plate 25 are connected to each other, and the first threaded hole 22 and the third threaded hole 26 correspond to each other. The quartz accelerometer adapter plate 12 and the hexahedron 11 are locked together by bolts passing through the first threaded hole 22 and the third threaded hole 26. The same principle applies to the installation of the suspension wire accelerometer adapter plate 13. After installation, the quartz accelerometer adapter plate 12 has other mutual mounting holes for debugging and testing other models of quartz accelerometers, and the suspension wire accelerometer adapter plate 13 has mounting holes for other models of accelerometers for debugging and testing other models of suspension wire accelerometers.
[0031] Furthermore, by using the adapter components, accelerometer adapter plates with different hole sizes can be installed, improving the adaptability of the accelerometer adapter plate installation and making it convenient and flexible to install and use.

[0033] In practical use, the first annular plate 35 fits into the second threaded ring 33, and the second annular plate 37 fits into the third threaded ring 34. They are locked together by bolts passing through the first round hole 36 and the second round hole 38. In this way, the first threaded ring 32, the second threaded ring 33 and the third threaded ring 34 can be locked together. When in use, the user moves the side plate 39 to connect the threaded post 31 with the third threaded hole 26. At this time, the distributed threaded rings correspond to the first threaded hole 22. For the first threaded hole 22 with different hole sizes, the first threaded ring 32, the second threaded ring 33 and the third threaded ring 34 with different diameters can be directly matched. They can be locked by bolts passing through the first threaded hole 22 and the corresponding threaded rings of suitable specifications.
