< Topic >After incorporating the support line to inside the spiral annulus, with revolution induction it possesses the convenience function and stable bearing capacity of attaching desorption, it offers the desorption unrestricted hook of the spiral annular structure which does not give the damage to the support line.SolutionsElasticity shift reversal looping the multiple spiral revolutions B with bending processing of belt F at optional position the middle, by the fact that it administers the reversal spiral C of the same number, the loop section left and right symmetrical helical structure body G and it is not by the median, median loop apex section E in order to become support axial A extended direction and isotopy direction of the left and right both ends, in direction outside spiral circle it bends in specified height initializes to buckle the Tip to the direction which is repulsive with spiral circumference direction, the support axis A of the helical structure body G left and right both ends it hangs in the target parent locks rear attaching desorption unrestricted spiralIt becomes the desorption hook.< Choice figure >Drawing 1【課題】回転誘導によって支持ラインを螺旋円環内へ取り込む後付脱着の利便機能と安定支持力を併有し、支持ラインに損傷を与えない螺旋円環構造の脱着自在フックを提供する。【解決手段】弾性硬線Fの曲折加工による複数の螺旋回転Bを途中の任意位置で反転折り返して同数の逆転螺旋Cを施し、折り返し部を中央に左右対称の螺旋構造体Gとなし、中央の折り返し頂点部Eを左右両端の支持軸A延長方向と同位方向となるよう、螺旋円外方向に曲折し所定の高さに立ち上げてその先端部を螺旋周回方向と相反する方向へ湾曲させ、螺旋構造体G左右両端の支持軸Aを吊り下げ対象母体に固定することで後付脱着自在の螺旋脱着フックとなる。【選択図】図1
