[0002] As one of the key electrical components in the nuclear power field, the nuclear-grade magnetic switch has extremely strict requirements for various indicators. Once a nuclear accident occurs, no matter how the environmental conditions change, the nuclear-grade magnetic switch should not be damaged or malfunction within the specified time. Therefore, the performance indicators of the nuclear-grade magnetic switch need to be tested using an anti-vibration and jitter tester. However, in the existing technology, when testing the nuclear-grade magnetic switch, the mounting base is fixed to the product vibration table by screws. When the direction needs to be adjusted, the screws need to be loosened and tightened after the mounting base angle adjustment is completed.
