An apparatus includes a handle having a first end and a second end; an
actuator attached to the handle; a tool plate for receiving a tool; a
connector attached to the second end of the handle for pivotally
connecting the handle to the tool plate; a hydraulic hose; and a
hydraulically actuated brake assembly which is in communication with the
actuator by the hydraulic hose. The brake assembly is preferably operable
to releasably hold the tool plate at a position relative to the connector
and the handle on operation of the actuator.
