Abstract
The invention relates to an apparatus for cutting threaded rods. This apparatus essentially comprises a frame (1) to which a square (2) is fixed by a bolt (6), the said square having a semicylindrical threaded nest (2a) at the top, and to which a moving part (3) is jointed, the said moving part being provided at the bottom with another semicylindrical threaded nest (3a) arranged opposite the one (2a) located in the fixed part (2). The moving part (3) is actuated by a force-multiplying lever (4). The threaded nests (2a and 3a) come to bear against the threaded rod (5) at the moment when cutting takes place, so as to preserve the integrity of the thread of the threaded rod (5). Application: building industry.
