ABSTRACT:
A tool for connecting a pair of pipes through a coupling pipe includes a handle connected to a curved member, a semicircular plate connected rotatably with the curved member through a link, and a crescent-shaped plate extending from the curved member. The curved member has a supporting point at the ends of its bending portion and a point of application at the top of its projecting portion. The semicircular plate is connected rotatably with the supporting point through a pair of links, and fixed close to an edge of a coupling pipe so as to settle the tool. The crescent-shaped plate is connected rotatably at its neck portion with the point of application of the curved member through a pair of middle links. A pair of upper and lower portions of the crescent-shaped plate are adapted to engage with the pipe to be connected with offsetting to the axial direction of the pipe.
