With the top cylinder of corresponding card tieholen side wall tight fit, the lower end for pushing up cylinder to the spacing and limit between limiting stand terrace
Position step surface is equal to the distance between lower sleeve bottom end；The Fastener can constantly move up under the passage of top cylinder, meanwhile,
When the arc male part of arc fixture block and the card tieholen side wall of lower sleeve offset, spring is compressed, and shrinks Fastener, until
It offsets at the top of Fastener with limiting stand terrace, elastic card tieholen holds lower part vertical reinforcement tightly.In this way, since Fastener is by more
A interval is arranged and the arc fixture block that is linked together by spring forms, and arc fixture block surround after for one there are multiple gaps
Cylindrical body, the presence based on the gap and spring, when external force squeezes arc fixture block, diameter becomes smaller after spring-compressed, therewith
The arc fixture block of connection i.e. can be radially mobile to center position therewith, and the gap between arc fixture block is made to become smaller, meanwhile, make wherein
Portion is formed by elastic clamping bore dia and becomes smaller, and then the lower part vertical reinforcement being placed in Fastener clamps.Fastener is not
