Multi-section supporting horizontal silicon core cutting device

The utility model discloses a multi-section supporting horizontal type silicon core cutting device which comprises a stand column and a cutting part installed on the stand column. The stand column is further provided with a supporting part. The supporting part comprises a fixing piece connected with the stand column and located below the cutting part. And the multiple sets of supporting pieces are arranged on the fixing piece, and each supporting piece comprises a supporting air cylinder, a supporting telescopic rod arranged at the output end of the supporting air cylinder and a supporting arc block installed at the end of the supporting telescopic rod. According to the utility model, a plurality of groups of supporting pieces are designed to support the silicon rod, so that the phenomenon that the silicon rod is bent and even broken due to the influence of self weight during cutting is avoided; meanwhile, through cooperative work of the multiple sets of supporting pieces, part of the supporting pieces can be
