Bird cage feeder (food cup) that is both stable and easy to remove

This is a bird cage feeder (or cup) that can be stably fixed with screws and is easy to remove directly for cleaning without completely disassembling the screws.

To temporarily remove an installed feeder, you can slightly loosen the nut, lift the cup upwards, and separate the cup's screw slot from the screw head.

To reinstall, simply align the screw head with the slotted groove, and it will easily snap into place.

A slotted tenon is designed inside the feeder's screw slot to limit the screw head and prevent it from slipping when tightening the nut.

Screws to prepare:

The screws should be cross-slot M6*30 pan head screws, or you can choose slotted M6 screws. If you want the screw rod not to protrude too much after tightening, you can choose M6*25 or M6*20 specifications.
Use M6 wing nuts.
