Mounting structure for steel sheet reinforcing sheet

According to the technical scheme, the mounting structure for the steel sheet reinforcing sheet comprises a rectangular frame body, positioning driving mechanisms are symmetrically arranged at the two ends of one side of the rectangular frame body, positioning assemblies are symmetrically arranged on one side of the rectangular frame body in the vertical direction, and each positioning driving mechanism comprises a driving block and two movable blocks distributed in the vertical direction; the top and the bottom of one side of the driving block are symmetrically connected with wedge-shaped inclined rods, and the ends, away from the driving block, of the two wedge-shaped inclined rods are fixedly connected with limiting plates. A user can respectively push the two driving blocks towards the middle part of the rectangular frame body so as to drive the two clamping plates to clamp the flexible circuit board and the reinforcing sheet, the flexible circuit board is clamped and fixed while the reinforcing sheet is
