ABSTRACT:
Hand operable apparatus for shearing thin-wall sleeve members to a precise, selected length without causing sidewall collapse, this apparatus comprising an elongate, generally cylindrical body having a partially hollow interior. An elongate support mandrel is mounted in a cantilever manner on the longitudinal centerline within the cylindrical body, with one end of the mandrel being supported adjacent one end of the generally cylindrical body. The other end of the mandrel is free and of a diameter such that the end of a thin-walled sleeve member to be cut to length can be closely received thereon. A cutoff device is operatively mounted on the generally cylindrical body adjacent the free end of the mandrel, which cutoff device can be brought forcefully into contact with the sleeve member at a selected location. The user can then accomplish shearing of the sleeve member by causing relative rotation between the cylindrical body and the sleeve member. The sleeve member can be supported by a holder adapted to be brought into carefully aligned contact with the mandrel before the shearing procedure begins.
