Under-desktop garbage bag holder

This design can be installed under a desk or work table, using ordinary plastic bags to collect garbage. The width of the bracket can be adjusted and fixed through the knob and gear mechanism, and it can be suitable for plastic bags of various sizes. It can be rotated out when in use and can be turned back under the table after use.

It can be fixed under the table with double-sided tape or screws.
