[MDL ED] Need help with custom lever

[The chaser]

Hi everyone!
So, my CS needed a custom lever. And I made it. But every custom thing always gives problems. The problems are the following ones:

-The lever base moves with the handle.
-It doesn't move up to down, it moves left to right. (An axis problem, but where's the F***ING axis option?)

I checked the joint, the bodies, but there's something that escapes from my knowledge. I'm sure that is something wrong in the joint (hinge).

Here is the lever (I know, it's very basic, but it's a lever.)





As always, it will be very silly, because I always find complicated things but I fail at simple.

Have a nice day!
