[0026] In this embodiment, by setting the bidirectional lead screw 602, the rotating bidirectional lead screw 602 can drive the two-sided nut seats 601 to move towards or away from each other.

[0027] Specifically, the connection relationship between the bolt 2 and the waveguide flange 1 is movable insertion.

[0028] In this embodiment, by setting the bolt 2, the waveguide flange 1 is assembled and connected to other external circuits through the bolt 2.
