The invention relates to a nut (10) comprising an outer body (16) with an axial passage (22), an inner body which can be movably placed in the passage along an axial direction and which is divided along said axial direction into at least two jaws (18, 20), each jaw bearing an inner thread segment (24) on its radial inner surface, first guiding means (26) located on the outer body, as well as second guiding means (30) located on the jaws and co-operating with the first guiding means so that the jaws are radially displaced towards the exterior when the outer body is displaced in the unscrewing direction relatively to the inner body et radially displaced towards the inside when the outer body is displaced in the screwing direction relatively to the inner body.

本发明涉及一种螺母(10)，它包括：一个带轴向通孔(22)的外体(16)；一个内体，位于通孔(22)中，可沿轴向移动，并且沿所述的轴向方向至少分成两个滑块(18、20)，它们各自在其径向的内表面上具有内螺纹部分(24)。在外体上有第一导向装置(26)，同样滑块上有第二导向装置(30)，第二导向装置与第一导向装置共同起作用，所以，当外体相对于内体沿旋松方向作相对滑移时，滑块径向地向外滑移，并且，如果外体相对于内体沿拧紧的方向滑移，则滑块径向地向内滑移。

The design means of nonfigurative inherit is a good means for historical region. The third arrangement is the whole city, it involves in different cities. Some cities have whole historical scene, so we should focus on the design of plane setup, urban layout, urban contour line and architectural style. The others should adopt the means of network design.
