    an annular tooth set is aligned on an inner bottom face of the circular shaft receptacle, and, a through hole is also reserved in the circular shaft receptacle;

    a lower clamping arm having a tail end extended upwardly to form a fixing piece, which stands oppositely to the fixing piece of the upper clamping arm, wherein a shaft bushing is secured transversely to the fixing piece of the lower clamping arm for being inserted coincidentally in the circular shaft receptacle of the upper clamping arm, and a polygonal store cavity is formed in center of the shaft bushing;

    a sound pickup cup, which is substantially a conic hollow body disposed in a slip receptacle of the upper clamping arm, and provided with a pipeline for extending outwardly;

    a weight block, which is substantially a polygonal solid body disposed between the store cavity of the lower clamping arm and the circular shaft receptacle of the upper clamping arm, wherein an annular tooth set is formed on a right face of the weight block for engaging with the annular tooth set in the circular shaft of the upper clamping arm, and a protruding part disposed in center of a right end of the weight block penetrates the through hole of the circular shaft receptacle to poke outwardly; and

    a spring loaded in the store cavity of the lower clamping arm having one end propped against the weight block for keeping engagement of the annular tooth set of the weight block with the annular tooth set in the circular shaft receptacle under normal conditions;

    by abovesaid arrangement, the internal annular tooth sets being detached apart when the protruding part of the weight block is depressed so that the opening and closing angle of the upper and the lower clamping arm can be adjusted easily, or, the relative position of those two clamping arms can be fixed because of the engagement of the annular tooth sets when the protruding part is released.
