摘要：A multi-folding screwdriver comprises a handle having a retainer formed therein; the retainer having a receiving space; a bottom end of the receiving space being installed with a first engaging portion; at least one via hole being formed in the retainer; a positioning element passing through the via hole; a driving bar being a multi-staged and bendable rod; a bottom end of the driving bar having a second engaging portion corresponding to the first engaging portion; an annular recessed limiting portion being formed at the driving bar. The driving bar is received in the receiving space so that the first engaging portion of the retainer is engaged to the second engaging portion. Thereby the retainer and the driving bar can rotate; and the positioning element passes through the via hole to resist against the limiting portion so as to forth as a limiting device.
