Clock disassembly tool

[Workshopshed]

I'm working on a clock project that requires the disassembly of an old clock. There was a nut holding the clock to the body with a slot for a screwdriver. The problem was that there were the spindles for the clock hands in the middle, in the way.

There's probably a proper horological name for this tool but I don't know what it is.
