Multi-faceted extension pole |
摘要 |
A pole for supporting a tool includes an elongate body extending along an axis. The elongate body defines a plurality of outwardly facing facets about the axis. The elongate body preferably includes a first tube and a second tube telescopically received within the first tube for adjusting a length of the pole. The two tubes are locked relative to one another by a locking mechanism that is fixedly coupled to the first tube with a detent engaging member that extends from the locking mechanism into engagement with a detent defined by the first tube. The locking mechanism preferably comprises a collet which is threadably coupled to a chuck that defines a plurality of outwardly facing facets. Rotation of the chuck causes the chuck to overlap the detent engaging member and to frictionally clamp the collet against the second tube.
