This is such an uncommon object that I’ll be giving a few more hints than usual. There’s a good chance that there’s something in your house that this thing played a role in making, especially if you have an expensive kitchen. While there are no motors in the device itself, it was designed to be used with a motor.
You can tell by all the adjustments that there is a precision element to this thing, and that’s precisely why it was invented: it lets people do something that couldn’t do very well without something like this.
Only very observant people are likely to have noticed this little guy’s handiwork, but there’s a particular profession that has a lot of respect it.
The two “spikes” in the “back” come out.
It’s a pocket hole jig. The two spikes at the back are actually drill bits. One drills a hole, and the other inserts a screw. You can see it being used here. The kind of joints it makes can be found here. While this is a fairly esoteric device, unless you buy stuff only from Ikea, you probably have some of these joints somewhere in your home.
