A ratchet screwdriver comprises a handle, a ratchet seat body, a rotary shaft rod, a stop plate, an anti-reverse plate, a dial knob seat, a recovery spring, a housing, a lock member, and a screw tip. The ratchet seat body is provided with a slide slot which is in turn provided with two slide edges capable of sliding back and forth along with the anti-reverse plate to support two gears mounted on the rotary shaft rod, thereby making the assembly of the ratchet screwdriver relatively simple.
