A closing structure that cooperates with the outer peripheral surface of the ripple spring 3 to apply a radial force to it is formed. During installation, the corrugated spring 3 is first pressed into the front section 201, and when the connecting nut 2 is pulled forward, the corrugated spring 3 will move to the rear section 203 under the guidance of the tapered surface of the conical structure 202, because The depth of the rear section 203 is relatively shallow, which will limit the radial movement of the corrugated spring 3 and apply a radial force to it, so as to avoid disengagement of the connecting nut 2 due to the excessive radial movement of the corrugated spring 3 . Of course, in other embodiments, an arc-shaped surface can also be provided at a position close to the rear section of the second installation groove; The closing structure of the rear part of the installation groove.
