手段とをそなえてなる管状試験片用つかみ具。 Consists of a combination of tooth bodies in the shape of an annular body divided into multiple arc shapes, with an external tooth whose inner peripheral surface is formed as a concave tooth surface and a tooth body in the shape of a circular body divided into multiple arc shapes. The outer circumferential surface is formed as a convex tooth surface with a smaller diameter than the tooth surface of the external tooth, and the inner circumferential surface is tapered along the axial direction such that the inner diameter is larger on the tip side and smaller on the rear end side. The internal teeth are formed as surfaces, the holder holds these external teeth and internal teeth, and the tapered outer peripheral surface has a large outer diameter on the leading end side and a small outer diameter on the rear end side. a tapered sleeve that is inserted and comes into close contact with the inner circumferential surface of the internal tooth; a connecting rod that supports the tapered sleeve;
A grip for a tubular test piece, comprising a biasing means for pushing and biasing the inner teeth in a diametrically expanding direction by a tapered sleeve by pulling the connecting rod rearward.
