发明名称 Lever bender and related method of use
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.

主权项 1. A device for bending a pipe comprising: a first handle including a forming mandrel having an outer edge and a stop member configured to receive and substantially prevent movement of the pipe relative thereto when engaged therewith, and a second handle pivotable relative to the first handle and including a forming head configured to engage and bend the pipe around the forming mandrel when the second handle is pivoted toward the first handle, wherein said stop member includes a pipe-engaging member configured to fittingly receive the pipe therein and a locking member adjacent to said pipe-engaging member, said locking member including a retaining member moveable between (I) a normally projecting position where said retaining member projects toward the pipe-engaging member and directly engages the pipe received in the pipe-engaging member such that the pipe is held between the pipe-engaging member and the retaining member, and (II) a retracted position where the retaining member is retracted away from the pipe-engaging member and is disengaged from the pipe received in the pipe-engaging member, and a biasing member configured to exert a biasing force on the retaining member and bias the retaining member toward the normally projecting position.
