ABSTRACT:
An extension rod assembly for manually positioning a tool head in contact with a work surface comprises an extension rod, a pivotable tool head, and a control linkage for locking the tool head in a selected angular position relative to the extension rod. The control linkage comprises an elongate connecting member which extends through the rod, a manually operable handle at the control end of the rod, and a clutch mechanism which is operated by the handle. The clutch has a first position in which it is disengaged from the connecting member, and a second position in which it is frictionally engaged to the connecting member in order to exert a linearly-directed force on the connecting member so as to actuate a locking assembly which locks the tool head in position. In the disengaged position, the clutch permits linear movement of the connecting member past the clutch and handle as tubular portions of the extension rod are telescoped to a desired length. In this manner, operation of the handle to select the disengaged position permits the operator.
