1. A squeeze mode giant electrorheological fluid damper, comprising:
a support, the support comprising a bottom plate, guide shafts and a top plate, the guide shafts being vertically fixed on the bottom plate, and the top plate being slidably arranged on the guide shafts; wherein one of the bottom plate and the top plate is used for being connected with a fixed platform, and another one of the bottom plate and the top plate is used for being connected with a load to receive vibration energy;
a container, the container comprising a container body and two spiral spring pieces coaxially arranged in the container body, the container body being fixed on the bottom plate, the bottoms of the two spiral spring pieces being fixed to a bottom of the container, and the two spiral spring pieces being not in contact with each other and being spaced by 180°; wherein the container body is made of an insulating material and used for accommodating an electrorheological fluid with reinforced rheological property; and each of the two spiral spring pieces is made of a conductive material, and the two spiral spring pieces are used for being connected with a positive electrode and a negative electrode respectively to generate an electric field; and
a connecting structure, a top of the connecting structure being fixedly connected with the top plate, a bottom of the connecting structure being fixedly connected with tops of the two spiral spring pieces, and the connecting structure being made of an insulating material.
