[0016] In this technical solution, the limiting port is used to prevent the outer conductor from falling off, further improving the stability of the RF coaxial floating probe when it is reused.

[0017] In some embodiments, the limiting end further includes a docking section connected to the limiting section, the docking section being disposed on the side of the limiting section away from the moving end, and the second spring being connected to the docking section.
