Fixing device for a fastening device for fixing a storage body to a storage surface of a storage device

A fixing device for a fastening device for fixing a storage body to a storage surface of a storage device, comprising:

• at least one base that can be fixed directly or indirectly to the storage surface of the storage device,
• at least one housing that surrounds the base or is fixed to the base,
• at least one clamping element that is arranged outside the housing on a side of the housing facing away from the base and can be moved relative to the housing, and
• at least one actuating unit, which comprises at least one actuating element, on which the clamping element is fixed in a rotationally fixed and stationary manner relative to the actuating element, and which comprises at least one actuator, by means of which the actuating element and the clamping element fixed to it can be moved from a release position by rotation about a rotational axis extending transversely to the storage surface into a pre-clamping position in which the actuating element and the clamping element are rotated relative to the release position about the rotational axis and are fixed against further rotation about the rotational axis, and by means of which the actuating element and clamping element can be moved from the pre-clamping position by translational movement parallel to the rotational axis in the direction of the housing into a clamping position in which the distance between the clamping element and the storage surface is reduced relative to the pre-clamping position.
