The work elements are movable between a first position at which the work elements are fully retracted and a second position at which the work elements are fully extended. A single lever mechanism controllably moves the work elements in response to controlled movement of a single lever of the lever mechanism. The lever is pivotally connected to the first assembly and connected to the second assembly and movable therewith.
