1. A driving end of a tool comprising:
a body including a chamber and a bore, with the chamber defining first and second sectional areas, with the bore extended into the second sectional area, with the second sectional area including first and second pawls each with a plurality of teeth on a first side thereof; a first engaging member rotatably disposed in the first sectional area and defining a first engaging section, with the first engaging section extended circumferentially on an outer periphery of the first engaging member and with a plurality of teeth; a second engaging member rotatably disposed in the second sectional area and defining first and second engaging areas, with the first engaging section engaged with the first engaging area, with the second engaging area selectively engaged with the first and second pawls, the second engaging area with a plurality of teeth extended outward from the first engaging area and circumferentially on an outer periphery of the second engaging member below the first engaging area; and a switch including an activating member inserted through the bore and operably rotatable about a fixed axis to first and second positions selectively, with the second engaging member rotated eccentrically about the fixed axis upon rotation of the switch, with the switch operated to the first position that an operation of driving the driving end of the tool in a first direction causes the second engaging member to move towards and include the second engaging area engaging with the first pawl and such that an object engaged with the driving end of the tool is able to be driven in the first direction and that an operation of driving the driving end in a second direction opposite the first direction causes the second engaging member to move away the first pawl and such that the driving end of the tool is in a freewheel rotation with respect to the object engaged therewith, with the switch operated to a second position that an operation of driving the driving end in the second direction causes the second engaging member to move towards and include the second engaging area engaging with the second pawl and such that an object engaged with the driving end is able to be driven in the second direction and that an operation of driving the driving end in the first direction causes the second engaging member to move away the second pawl and in a freewheel rotation with respect to the object engaged therewith. |
