ABSTRACT:
A handle tool comprises a spanner body; at least one opening being formed at one end of the spanner body; an inner wall of the flower form opening being formed with a resisting portion; the resisting portion being formed with a plurality of ratchet teeth for buckling an elastic restoring unit; a smooth portion at an lower edge of the resisting portion; a diameter of the smooth portion being slightly larger than that of the resisting portion. Thereby, when a hexagonal screwing unit of the screw unit buckled against the resisting annual element will be received in the smooth portion of the flower form opening. Since no ratchet tooth is formed on the smooth portion and the diameter of the smooth portion is slightly larger than that of the hexagonal screwing unit of the screw unit, the spanner body will rotate idly.
