    • A connection (21) for connecting structural elements (1, 2) at an angle with selectively variable amplitude comprises at least one cylindrical pin (3), having two consecutive bodies (4, 5), of which a first body (4) has grooves on the outside and a second body (5) is smooth. Two arms (6, 7) have corresponding ends (6a, 7a) with holes (8, 9) through them, delimited by surfaces (10, 11) for surrounding the pin (3) and grooved like the first body (4). The arms (6, 7) and the pin (3) can move relative to one another along an axial direction (12) of the pin (3) and between two end positions. In a first end position, the first, grooved body (4) of the pin (3) and the surfaces of the arms (6, 7) are integral with one another with respect to the relative rotation about the axial direction (12) of the pin (3), whilst in the second end position at least one of the arms (6, 7) is at the second body (5) of the pin (3), so that it can rotate freely relative to the pin (3).
    • 一种用于连接结构元件的连接(21)(1,2)在与在选择性可变振幅角包括至少一个圆柱形销(3),具有两个连续的机构(4,5),其中的第一主体(4)具有 在外面和第二主体(5)的槽是平滑的。 两个臂(6,7)具有相应的端部(6A,7A)具有孔(8,9)通过它们,由表面(10,11),用于围绕所述销(3)限定,并且带槽状第一主体(4)。 所述臂(6,7)和所述销(3)可以相对于沿在所述销(3)的轴向方向(12)移动到彼此和两个端部位置之间。 在所述销(3)的第一端部位置时,第一,有槽主体(4)和所述臂的表面(6,7)是彼此整体相对于绕的轴向方向(12)的相对旋转 销(3),而在第二端部位置的至少一个臂(6,7)在第二主体(5)的销(3),所以这样做是可以自由地相对于销旋转(3 )。
