Description

Debugging structure and filter thereof Technical Field The application relates to the technical field of communication, in particular to a debugging structure and a filter thereof. Background In the prior art, the resonant rod of the cavity filter is arranged in the cavity, the top of the cavity is provided with a cover plate, a threaded hole is machined on the cover plate before the cover plate, the periphery of the debugging screw is provided with threads of the matched threaded hole, and the two are screwed together through the threads so as to enable the screw to extend into the inner hole of the resonant rod of the cavity. The adjusting screw adjusts the position in a mode of up-and-down rotation of the threads, and a user can adjust the height position of one end of the adjusting screw in the resonator according to requirements, so that the resonant frequency is changed. However, because the threaded structures of the debugging screw and the cover plate cannot completely fix the column debugging screw and the cover plate, two conditions of moving the cover plate and the debugging screw rotationally upwards away from the resonant rod and moving the cover plate rotationally downwards close to the resonant rod still occur. In view of this, how to effectively ensure that the debugging screw rod and the cover plate can be fixed and not moved, and simultaneously can achieve simple adjustment of the distance between the upper and lower displacement debugging screw rods and the resonant rods, which is a problem to be solved at present. Disclosure of Invention The embodiment of the application provides a debugging structure which can solve the problem that the distance between the debugging screw and a resonance rod can be adjusted simply by adjusting the upper and lower displacement between the existing screw and a cover plate, so that the debugging screw and the cover plate cannot be fixed.
