Abstract
The invention relates to a structure of a screw driver with a ratchet gear, in particular to the ratchet gear of the screw driver and the screw driver using the ratchet gear. The ratchet gear of the screw driver comprises a pawl seat, a ratchet shaft, an outer clamping ring and two pawls. When the ratchet gear is located at a locking state normally, and the outer clamping ring is rotated in a clockwise direction, a toggling protrusion pushes the left pawl to move outwards along the first inclined surface so as to enable the ratches on the left pawl and a strip tooth to demesh; when the ratchet gear is located in an anticlockwise rotation state, and the outer clamping ring is rotated in an anticlockwise direction, the toggling protrusion pushes the right pawl to move outwards along the first inclined surface so as to enable the ratches on the right pawl and the strip tooth to demesh; and the ratchet gear is located at a clockwise rotation state. The invention has the characteristics that the structure of the ratchet gear is simplified, the production cost is reduced, and the service life is long.
