Stud removing tool

摘要

An improved stud removal tool comprises a cylindrical socket having an open end communicating with a coaxial cavity and a shank extending coaxially adjacent the socket opposite the open end, the shank terminating opposite the socket in an anvil end adapted to cooperate with a driver such as an impact wrench for turning the socket. A plurality of axially extending cams extend on the interior wall of the socket vary the radius of the cavity at evenly distributed positions. The cams radially engage an equal number of gripping jaws contained within a removable cartridge which is free to shift relative to the socket within the cavity. The cams thereby inwardly bias the jaws for gripping a stud inserted into the cavity between the jaws. The cartridge comprises a cylindrical unit made up of the jaws separated by resilient blocks bonded to the edges of the jaws and serving to space the jaws to keep them mated with the cams. The spacer blocks also radially bias the jaws outward against the cams.
