Sample container carrier, laboratory sample distribution system and laboratory automation system

A sample container carrier for holding a laboratory sample container and for transporting the held laboratory sample container in a laboratory sample distribution system, the sample container carrier comprising:

• a first holding element;
• a second holding element, wherein the first holding element and the second holding element are translationally displaceable towards and/or away from each other for holding the laboratory sample container, wherein the first holding element and the second holding element are translationally displaced along a parallel plane perpendicular to a central axis;
• a coupler, wherein the coupler is connected to the first holding element and to the second holding element such that the coupler couples translational displacements of the first holding element and the second holding element with each other;
• and
• at least one slanted surface coupling, wherein the coupler is connected to the first holding element and/or to the second holding element by the at least one slanted surface coupling, wherein the at least one slanted surface coupling comprises a protrusion and a protrusion guidance translationally moveable to each other, wherein the protrusion guidance comprises at least one slanted surface, and wherein the protrusion is configured to cooperate together with the slanted surface for the translational movement.
