Abstract

The present patent relates to chain pipe-cutters equipped to cut all kind of material. The chain pipe-cutters include: a tensioner which is a deformable system formed by a cylindrical rod fast with a support, a slider slidably mounted on said rod, said support bearing four articulated rockers connected to the slider in pairs by two links and having their lower ends shaped as hooks to permit attachment of the chain thereon; said cylindrical rod cooperating with a handle through the agency of a screw-thread and said handle being formed by two superimposed cylindrical elements and having four superimposed lobes arranged cruciform-fashion.
