Novel low-frequency damping shock absorber

The novel low-frequency damping shock absorber comprises a permanent magnet vibrator, a sliding saddle, an upper energy absorption spring, a lower energy absorption spring, a connecting rod, a coil and a supporting frame, and the supporting frame comprises a bottom plate, a rib plate, a sliding rod and a top plate; a plurality of rib plates and a plurality of sliding rods are connected to the bottom plate; lower energy absorption springs, sliding saddles and upper energy absorption springs are sequentially connected to the sliding rods from bottom to top in a sliding mode, the permanent magnet vibrator is rotationally connected with the sliding saddles through a plurality of connecting rods, and the permanent magnet vibrator is located among the sliding rods. A closed coil surrounds the periphery of the rib plate; the top of the sliding rod is connected with the top plate. When vibration is generated, the permanent magnet vibrator serves as a vibration absorption mass block and plays a role in vibration reduc
