Abstract

The present invention relates to a ratchet screwdriver, comprising: a holding grip and a ratchet unit installed on the holding grip. The ratchet unit comprises a positioning seat fixed on the holding grip, a ratchet wheel axially disposed in the positioning seat, two tugging pieces installed between the positioning seat and the ratchet wheel, two flexible components providing the tugging pieces with the shift inclination to face the ratchet wheel, and a screw cap covering the positioning seat. The tugging pieces have a plurality of latching teeth corresponding to the indents and convex parts installed on one side. The screw cap has a driving part capable of tugging the convex parts of the tugging pieces; thus, the coupling direction can be switched by the rotation of the screw cap.
