In order to solve the technical problem, the utility model discloses a technical scheme does:

the utility model provides a balance platform, includes the support and sets up the mesa on the support, be equipped with four internal thread holes on the support, four external screw thread poles are installed in the cooperation in the internal thread hole, the mesa includes solid physics and chemistry sheet layer and granite stratum, the mesa bottom is equipped with four blind holes, four the end that stretches out of external screw thread pole inserts in the blind hole, four the cover is equipped with adjusting nut and fastening nut separately on the external screw thread pole, the support bottom is equipped with the rubber pad, be equipped with first spirit level and second spirit level on the mesa.

Preferably, a round sleeve with one closed end is arranged in the four blind holes.

Preferably, the adjusting nut is a hexagonal flange nut.

Preferably, the hexagonal flange nut has its flange facing downward.

Preferably, the adjusting nut is sleeved with an adjusting handle, and the fastening nut is sleeved with a fastening handle.

Preferably, the first level and the second level are arranged at right angles.

Preferably, the adjusting nut is disposed at a lower side of the fastening nut.

Adopt above-mentioned technical scheme, because be equipped with four internal thread holes on the support, four external screw thread poles are installed in the cooperation in four internal thread holes, and the mesa bottom is equipped with four blind holes for the roughness of mesa can be adjusted, because be equipped with first spirit level and second spirit level on the mesa, make the horizontal and longitudinal direction's of mesa roughness measure, adjust according to data again, owing to be equipped with the rubber pad, make the sky platform have the shock attenuation effect.
