The anti-seismic support mechanism comprises a supporting part provided with a first groove and a top beam part arranged above the supporting part, the side, close to the supporting part, of the top beam part is provided with a first connecting face, a connecting part is arranged on the first connecting face, and the end, away from the top beam part, of the connecting part is arranged in the first groove; when the magnitude of an earthquake is smaller than or equal to a first preset threshold value, the connecting part can absorb vibration energy generated by the earthquake, and when the magnitude of the earthquake is larger than or equal to a second preset threshold value, the connecting part is broken, and the vibration energy transmitted to the connecting part by the earthquake is released. According to the invention, targeted constraint adjustment on the end part of the supporting part is realized at different earthquake levels, the response accuracy of earthquake at different earthquake levels can be imp
