1. A quick removal socket tool adapted for mounting removably a screwdriver head that has an outer surface formed with a ball-engaging groove, the quick removal socket tool including a rod body having a front end surface formed with an axially extending recess, and a retention device for locking releasably the screwdriver head in the recess, characterized by:
the rod body further having a surrounding wall that defines the recess and that is formed with a retaining hole in spatial communication with the recess, and a slide slot unit formed in an intermediate portion of the rod body, in spatial communication with the recess, and having a front end and a rear end; a driving device including a guide pin extending movably in the slide slot unit and having two ends extending out of the rod body, and a first resilient member biasing the guide pin toward the front end of the slide slot unit; and the retention device including a sliding sleeve that is sleeved movably on the rod body and that has an inner surface formed with an annular groove, a second resilient member biasing the sliding sleeve) rearwardly to contact the guide pin and having a spring force smaller than that of the first resilient member, and a positioning ball received within the retaining hole; wherein the sliding sleeve is movable relative to the rod body between a retaining position and a release position such that, when the sliding sleeve is disposed at the retaining position, the annular groove is misaligned from the retaining hole so that the positioning ball is disposed within the retaining hole and the ball-engaging groove, the screwdriver head is retained within the recess, and the guide pin is disposed at the rear end of the slide slot; and when the sliding sleeve is disposed at the release position, the annular groove is aligned with the retaining hole so that the positioning ball is disposed within the retaining hole and the annular groove, the screwdriver head is removable from the recess, and the guide pin is disposed at the front end of the slide slot.
