Abstract

The invention is to provide a ratchet screwdriver capable of switching rotation direction, mainly composed of a handle, a screwdriver rod body, and a ratchet switch device, wherein the screwdriver rod body is assembled to the front end of the handle; a buckle member provided for buckling the screwdriver rod body is disposed on the handle; the ratchet switching device is disposed in the containing chamber at the rear end of the handle; and the ratchet switching device is composed of a seat body, a coupling seat, two latch blocks, a positioning seat, a clip spring, two positioning pieces, a ratchet, and a switching button. Accordingly, with the buckling or releasing of the buckle member on the handle, screwdriver rod bodies having different functions can be replaced, and the direction changing of the ratchet braking is switched by the switching button at the rear end of the handle, capable of facilitating the screwdriver rod body to rapidly perform operational utilization with different rotation direction braking .
