Quick links are pretty much the very last thing I would use. They'd have to be horrendously oversized to even begin to meet the load requirements.
A shackle is an eight second job, and with a marlinspike on hand can be snugged up enough for an overnight hook.
I wouldn't trust anything else, even a carabiner. What's the hurry?
I once wrapped a plastic bag around my outboard engine prop in a narrow channel with rock rip-rap on all sides and wicked currents, and had, I repeat HAD, to deploy my anchor IMMEDIATELY. It was ready, clamped onto a bow pulpit holder, with chain and rode in our shallow Catalina 25 locker.
You don't have a locker.
So, if it was my boat, I'd carefully analyze where I sailed. If I was going to an area like where I had my experience, I'd get the gear OUT on deck, all hooked up and ready for immediate deployment. If, however, I was going to be out on ONLY on wider waters, as is often the case for us and for many of you, then, and only then, would I even begin to consider having any arrangement that required any additional steps before I could drop the hook.
Your boat, your choice, but: What's your entire boat worth to you?
An anchor is SAFETY gear. Please, don't skimp.
Good luck.
