Tool system with rotatable tool

摘要

Tool system (10) advantageously provides tool (12), adapter (14) and extension member (16) successively coupled so that groove (34) mates with rib (44) in the assembled position. Groove (34) and rib (44) are engaged so that tool (12) is axially fixed relative to adapter (14) yet is axially rotatable relative thereto. In preferred embodiments adapter body (36) includes a shoulder (42), and adapter (36) and handle member (20) are correspondingly tapered with increasing radius from top to bottom so that the snapping, engaging action of handle member (20) on adapter head (36) is enhanced when the system (10) is assembled.
