1. A cavity filter, comprising:
a housing, comprising a body and an adjusting end cover, wherein the body and the adjusting end cover form a resonant cavity, and the adjusting end cover has a deformable region;
a resonator installed in the resonant cavity, opposite to the deformable region and spaced a predetermined distance from the deformable region; and
a driving assembly, comprising a driving body, wherein the driving body is connected to a side of the deformable region away from the resonant cavity and operatively drives the deformable region to move toward and away from the resonator;
wherein the adjusting end cover further comprises a fixing region arranged around the deformable region, and the adjusting end cover is fastened on the body through the fixing region;
the driving assembly further comprises a support member, the support member is fixed to the adjusting end cover through the fixing region, the support member has a constraining part, and the constraining part is adapted to the driving body and has at least one constraint position in a movement stroke of the driving body.
