Abstract

PURPOSE: To draw a cylindrical body by simple operation by connecting and disconnecting a slip and the cylindrical body by the rise and fall of a wedge body when drawing the cylindrical body.
CONSTITUTION: A proper wedge body 3 is attached to a lifting lever 1 by means of a nut 23 in response to an inner diameter of a cylindrical body 12, and the wedge body 3 is let fall up to a fixed location. A sleeve 4 is loosely fitted to the lifting lever 1, and lowered by means of a hanging rope 6. When pulling up the lifting lever 1, a conical surface section 2 of the wedge body 3 contacts with an inner surface of a slip 11, and the slip 11 is outward removed. When both closely contact, the slip 11 moves in parallel by oscillation at shafts 10 and 9, and a tooth section 13 on an outer surface tightly contacts with an inner wall surface of the cylindrical body 12. When further pulling up the wedge 3, the cylindrical body 12 bitten by the tooth section 13 is upward moved.
