ABSTRACT:
A screwdriver includes a handle, a first body having an end securely mounted in the handle, a second body rotatably mounted in the first body, a ratcheting mechanism slidably mounted in a receiving section in the other end of the first body, and a switch member pivotally mounted to the other end of the first body. The switch member is pivotable between a first position and a second position to control engagement/disengagement of the ratcheting mechanism with/from teeth of the second body and to control relative rotation between the first body and the second body. A reinforcing member is provided in the receiving section to withstand high-torque operation.
