Integrated plate with high stability

According to the technical scheme, the high-stability integrated plate is characterized by comprising a plate body, and a stabilizing seat is arranged below the plate body; the cross section of the stabilizing seat is of an isosceles trapezoid structure; an inserting end and a matching end are arranged at the two ends of the stabilizing seat; the plugging end comprises a through hole formed in the end part of the stabilizing seat; a movable column is arranged in the through hole; a limiting ring is arranged at the opening of the through hole; the movable column can be detachably matched with the matching end; the limiting ring is used for limiting the movable column; the movable column is axially and movably arranged in the through hole; the through hole is used for circumferentially limiting the movable column; a limiting block is arranged at the end, away from the limiting ring, of the movable column. The integrated board fixing device has the beneficial effects that fixing is firm, a plurality of integrate
