<p>An adjustable fluid collecting device with two shells (1, 2) pivotally movable relative to each other wherein the fluid collecting device is movable between an open position in which the shells are distanced from each other and a closed position in which the shells touch, an actuator (6) and a lever assembly (12, 13) wherein the operation of the actuator results in equal but opposite movement of the shells and the mechanical advantage increases as the shells move toward the closed position. A rigid frame (20) which substantially surrounds the two shells, actuator and lever assembly is provided. Optionally, the apparatus can be equipped with an integral pipe spinner.</p> |
