A precision screwdriver having a turning head includes an accommodation space provided inside a longitudinally extended handle of the precision screwdriver, the accommodation space being open at a wider diameter end of the handle, a holder in the accommodation space, a plurality of ribs each with a locking trough formed in the holder to hold a plurality of tips. A pivot is formed on one end of the holder and an opposing end has a fender formed thereon. The pivot is pivoted to the center of the turning head. A circular protrusion and a groove are provided at where the turning head contacts the accommodation space of the handle with both connected to each other for free pivoting and the turning head functioning as a support axle for the handle. The holder is exposed by pulling the turning head linked to the pivot, and is restricted in the circular trough of the accommodation space by the fender.
