Anti-seismic support with high stability

The utility model relates to the technical field of anti-seismic supports, in particular to an anti-seismic support with high stability, which is characterized in that a support device comprises an extension plate, the extension plate is slidably connected with the inside of a base, a handle is fixedly mounted on the surface of one end, far away from the base, of the extension plate, and an inclined support rod is hinged to the surface of the extension plate; two strip-shaped plates are fixedly installed on the side face of the base, sliding grooves are formed in the surfaces of the strip-shaped plates, first springs are fixedly installed in the sliding grooves, sliding blocks are fixedly installed at the ends, away from the sliding grooves, of the first springs, multiple clamping grooves are formed in the side face of the extending plate, clamping plates are fixedly installed on the surfaces of the sliding blocks, and grooves are formed in the side faces of the strip-shaped plates. And a moving plate is slid
