  • MINIATURE PIN EXTRACTING DEVICE
    Publication number: 20130276300
    Abstract: Provided is a miniature pin extracting device for extracting a miniature pin inserted into a part. The miniature pin extracting device includes a coupling having a polygonal pillar shape, the coupling having a lower end coupled to the locating pin, a retainer mounted outside the coupling, and a screw part supported by the retainer, the screw part being coupled to an upper end of the coupling. Thus, a rotation force of the screw part may be converted into a vertical axial motion through the retainer to safely extract the locating pin without lateral force and rotation, thereby minimizing damage of the part.
