摘要

Four equilateral right-angle triangles are formed, to act as clamping members (1), with the hypotenuse on the outside. The ends of the wire (3,4) are overlapped, and form the hypotenuse of one of the triangles. There is a double indented region with an outward extending clamping tongue (2) between each equilateral right-angle triangle.
