Multi-stage shock insulation friction pendulum support with anti-pulling function

The invention relates to the field of building shock insulation, and particularly discloses a multi-stage shock insulation friction pendulum support with an anti-pulling function. The multi-stage shock insulation friction pendulum support comprises an upper sealing plate and a lower sealing plate, wherein bolt holes are reserved in the upper sealing plate and the lower sealing plate; a middle block body is fixed to the bottom of the upper sealing plate, a coaxial sleeve is connected to the middle block body, the sleeve comprises two same circular truncated cones which are fixedly connected, and the diameters of the circular truncated cones are gradually increased from top to bottom; a circular groove is formed in the lower sealing plate, a lower support is fixedly connected into the groove through bolts, a connecting groove with a partial spherical surface shape is formed in the lower support, and the connecting groove abuts against the middle block body; an upper platform and a lower platform are arranged on
