Therefore, means must be provided on the second housing shell and on the drive unit, which ensure that the drive unit engages precisely when fitting the housing shell in the intended anchoring points. These provisions complicate and increase the cost of the hand mixer design. It is also difficult to verify after installation of the drive unit as part of the production control, if the drive unit actually sits correctly.
