Radio frequency adjustment structure reducing influence of metal debris

A radio frequency adjustment structure, comprising:

• a box base;
• a cover plate covering the box base to define a functional cavity between the cover plate and the box base, the cover plate comprising a top surface facing away from the functional cavity and a bottom surface facing the functional cavity for defining a vertical direction, the cover plate defining a through hole communicating the top surface with the bottom surface along the vertical direction;
• an adjustable screw rod being positioned to the cover plate, penetrating through the through hole, and partially extending into the functional cavity;
• and
• a debris collector comprising a first component and a second component, the first component being disposed at a position corresponding to the through hole of the cover plate and extending beyond the bottom surface toward the functional cavity, the first component surrounding the adjustable screw rod, and the second component being disposed just below the first component in the functional cavity.
