Abstract
A ratchet screwdriver includes a handle, a main body, a shank, two check plates, a shifter, a position confining plate, and a tubular housing. The check plates are provided with an inclined edge, a reinforcing edge and a protruded edge. The inclined edge is intended to enable the check plates to be effectively actuated by the shifter. The reinforcing edge serves to enhance the structural strength of the check plates. The protruded edge serves to prevent the check plates from displacing. The main body is provided with two protruded ribs to securely position the tubular housing. The position confining plate is provided with two pillars, with one end of the pillars being received in the guided slot of the main body, and with the other end of the pillars being fitted into a recovery spring to enable the position confining plate to return to its original position.
