Anti-pulling double-layer and double-pendulum type friction pendulum shock insulation support

The invention discloses an anti-pulling double-layer and double-pendulum type friction pendulum shock insulation support. The shock insulation support comprises an upper base, a transition base, a lower base, an upper sliding block, a lower sliding block, two upper anti-pulling pieces and two lower anti-pulling pieces, and the front side face and the rear side face of the upper base are each provided with a first sliding groove; the front side face and the rear side face of the transition base are each provided with a second sliding groove; the left side face and the right side face of the transition base are each provided with a third sliding groove; the left side face and the right side face of the lower base are each provided with a fourth sliding groove; every two of the upper base, the upper sliding block and the transition base can generate relative friction translation sliding in the left-right direction; every two of the transition base, the lower sliding block and the lower base can generate relative
