Claims

[Scope of utility model registration request]

A gripping member made of a pipe, one leg member having its tip connected to one end of the gripping member by an appropriate means, and a screw shaft inserted on the center line within the gripping member and having one end fixed to the gripping member. , an annular body that is fitted into the other end of the gripping member with the other end of the screw shaft passing through the central through hole, and a threaded portion on the outer and inner peripheries provided to protrude from the outer end surface of the annular body. The other leg member has a threaded part on the inner periphery of the tip screwed into the threaded part on the outer periphery of the protruding cylinder to connect to the other end of the gripping member, and a threaded part on the outer periphery of the tip is screwed into the threaded part on the inner periphery of the protruding cylinder. A cylindrical body screwed into the cylindrical body, a conical nut located on the distal side of the cylindrical body and screwed onto the screw shaft, and when the conical nut moves in the direction of the protruding cylinder, the diameter expands and presses the outer periphery against the inner periphery of the cylindrical body. A gripping tool consisting of a sleeve having a slit built into the cylindrical body, and mounting portions provided at the ends of both leg members.
