发明名称 Two-stop wrench
摘要 The present invention is an apparatus, including wrenches, to facilitate the installation and replacement of mechanical devices, particularly plumbing compression fittings such as angle-stop valves. The apparatus has a first member that includes an open-end wrench with three-jaw surfaces and a hollow handle extending therefrom. A second member also includes an open-box wrench and a handle extending therefrom, the handle of the second member being of a diameter small enough to slidably fit within the handle of the first member. The handles of the first and second members preferably including mating fasteners so as to enable the temporary locking of the two members for use and or storage of the two-pieces of the apparatus. The handle of the second member further includes at least two positioning members extending therefrom, one being retractable, and having certain sizes so as to allow the positioning member end of the wrench to engage the inner diameter of angle-stop valve of different sizes during installation.
