TECHNICAL FIELD

[0002] Filters play a very important role in the processing of electronic signals, can make the specific frequency components in the signal pass through, and greatly attenuate other frequency components. Filters are widely used in communication fields such as radio frequency and microwave, among which metal filters are widely used. With the gradual widespread use of 5G technology, each 5G base station will include about 64 filters. This urgently requires reducing the production cost of metal filters. In order to supplement the structural features, the current traditional metal filter needs to punch holes on the cover plate first, and then install the adjusting screw and nut, and the depth of the adjusting screw is used for tuning, and after tuning at all frequencies, the nut is used for locking. This method has relatively complicated process steps. It is produced by skilled workers through manual work, but the traditional manual work process requires very high proficiency, and individual ability has a great influence on the production efficiency and production quality of the product, which leads to the increase of the wages of the operating personnel and the increase of the competition cost. In order to fundamentally solve this problem, the screw-free metal filter without adjusting screw is currently developed. In the prior art, the screw-free metal filter needs to be tuned, and high-speed impact on the cover plate at different positions is needed during tuning. However, the current impact device has low automation degree, too many manual auxiliary process steps, and therefore the debugging efficiency is low. SUMMARY

[0005] Under the pressure action of the compression spring, the bearing wheel and the eccentric wheel are always in contact.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the utility model can completely replace manual debugging, so that the automatic debugging of the free-adjusting screw metal filter can be stable and efficient, and the utility model is more stable and efficient than manual debugging.
