    摘要： A lever bender includes a first handle pivotally attached to a second handle. The first handle includes a forming mandrel around which a pipe is bent and a stop member for receiving and substantially holding the pipe in place prior to bending. The second handle includes a forming head that engages and bends the pipe around the forming mandrel. The stop member includes a pipe-engaging member that receives a pipe and a locking member adjacent to the pipe-engaging member. The locking member includes a retaining member moveable between a projecting position where the retaining member secures the pipe between the pipe-engaging member and the locking member and a retracted position permitting a pipe to either be received within the pipe-engaging member or removed from the pipe-engaging member.

    摘要： A hydraulic tube expander includes expanding jaws engageable with an interior surface of a tube to expand the tube; a source of hydraulic fluid, a valve located between the source and the expanding jaws and a single-action release actuator operatively coupled to the valve. The valve is moveable between open and closed positions. In the closed position, hydraulic fluid can pass from the source to the expanding jaws and in the open position the hydraulic fluid can pass from the expanding jaws to the source. The actuator is movable between first and second positions. In the first position the valve is in the closed position. Movement of the actuator in a direction from the first position toward the second position moves the valve into the open position.
