The control mechanism is movable among a first position where the control mechanism is positioned in a selected one of the holes in the extension rod, and the tube, the extension rod and the control mechanism are prohibited from moving axially with respect to one another; a second position where the extension rod and the control mechanism together are allowed to move axially with respect to the tube; and a third position where the extension rod is allowed to move axially with respect to the control mechanism and the tube.
