The invention relates to a butterfly clamp. The butterfly clamp comprises: a body formed by integrating elastic plates and clamping surfaces together, and providing clamping parts; first and second clamping bars, each fitted with both sides of each clamping surface of the body, and constructed to open the clamping parts; first and second swivel joints arranged to rotate around the ends of the first and second clamping bars; first and second supports, each fitted and clamped with a corresponding joint among the first and second swivel joints, and constructed to have the same torsional shape and torsional force; and a coupling tube providing a connection hole constructed such that the second ends of the first and second supports are clamped to both sides of it and connected to the coupling tube, and constructed to have the same torsional force and rotating threads on the inner surface of the connection hole. |
