This invention, the screw, and being optional, offers the screw because it locks the rod & rod fixed assembly. The screw & rod fixed assembly, includes with the screw and fixed mechanism and the abbreviation annular ring and rod arrival seat mechanism and person in charge stopping mechanism. This invention offers also the fixed mechanism because the screw is locked, fixed mechanism furthermore includes the internal wall which possesses the grip part and the non grip part. Furthermore, this invention offers the abbreviation annular ring, guides machine power and frictional force to the screw head and offers. Furthermore, this invention offers rod arrival seat mechanism, this rod arrival seat mechanism operation is engaged possibly in the screw head, includes one which can be compressed among them vis-a-vis the portion of the rod flexible part at least. Lastly, this invention offers the person in charge stopping mechanism in order in the rod and rod arrival seat mechanism to engage. Person in charge stopping mechanism the occasion where person in charge stopping mechanism rod arrival seat mechanism furthermore engages at least in one flexible part bending/discouraging includes the bending/discouraging mechanism in order around this at least one flexible part of rod arrival seat mechanism vis-a-vis the rod.本発明は、ねじ、及び任意でロッドを固定するためのねじ・ロッド固定アセンブリを提供する。ねじ・ロッド固定アセンブリは、ねじと、固定機構と、略環状のリングと、ロッド着座機構と、係止機構とを含む。本発明は、ねじを固定するための固定機構も提供し、固定機構は、把持部分及び非把持部分を有する内面壁を更に含む。更に、本発明は、略環状のリングを提供し、機械力及び摩擦力をねじ頭部に案内し提供する。更に、本発明は、ロッド着座機構を提供し、このロッド着座機構は、ねじ頭部に作動可能に係合されており、ロッドの一部に対して中で圧縮できる少なくとも1つの可撓部分を含む。最後に、本発明は、ロッドとロッド着座機構とに係合するための係止機構を提供する。係止機構は、係止機構がロッド着座機構の少なくとも1つの可撓部分に更に係合する際にロッド着座機構の少なくとも1つの可撓部分をロッドに対してこの周りで屈撓するための屈撓機構を含む。
