The problem with my Sencor shb 5608bk-eue3

This is the problematic part of the set

The upper part, which is connected to the handle with the motor, looks like this

On the photo above it's missing this small plastic part, which broke down (because I was trying to blend something too hard)

At first I just tried to piece it back together using glue "Moment", but after trying to use the food processor again, the glue just didn't hold up. Any ideas how I can fix it?
