SYSTEM OF FASTENING ELEMENTS DEFINED BY A NUT AND A DRAWBAR; DRAWBAR AND NUT

摘要

The system (100) of fastening elements formed by a coupling rod (2) and a nut comprises a support structure or blade (30) provided with resilient tongues. The tongues will bend upward during a rotationless translation of the coupling rod along the nut. After further tightening by means of rotation in an opposite longitudinal direction the tongues are pressed flat against a stop surface (93) of the base body. As a result the support structure (30) fixes itself into the base body (9).
