Part forms, and 7 center of metal cone is useful for the through hole positioned to probe, the through hole at metal cone center, hollow
The through hole of metal column bottom is located at the through hole of 2 bottom of resonator cavity on same axis, and the hollow metal column 5 is visited with metal
Pin 8 keeps electrical contact；Metal probe 8 is placed in the through hole at the metal cone center in clamping device, when rotating bolt makes spiral shell
When bolt moves down, bolt can promote solid metal column and metal cone to move down, until metal cone and hollow metal column
The inner wall of bottom fits closely, you can clamps probe, probe can then be realized and visited by hollow metal column and the through hole of cavity bottom
It surveys.
Further, the solid metal column 6 sets a threaded hole close to one end of bolt, to facilitate solid metal column
It takes out.
Further, when the protrusion on the solid metal column 6 coordinates with the groove in metal cone, can closely paste
It closes, can also there is gap.
Further, the cavity of the resonator it is engaged through the thread with cavity upper cover together with, the through hole 3 of cavity upper cover
It is electrically coupled or magnetic-coupled coaxial probe or coaxial rings for installing.
Beneficial effects of the present invention are：Probe conveniently and efficiently can be placed in resonator by Multi-beam klystron of the present invention
On center conductor, it can accurately ensure horizontal plane of the probe perpendicular to lower face, positioned at the center of resonator；The resonator can be square
Just metal probe is quickly installed and replaces, and metal probe keeps making electrical contact with hollow metal column, does not interfere with measuring accuracy.
