1. A material analysis device for analysing a material sample,
having;
a sample chamber, and
a sample holder, which is supported by at least one pillar and protrudes into the sample chamber, and
a loading shaft having one end to which force is applied by an exciter and an other end which bears a probe shaft, wherein the probe shaft transmits the force to the sample in a defined manner and thereby loads the sample,
wherein the loading shaft forms a bushing at the other end facing the sample chamber, the bushing accommodating an insertion section of the probe shaft when in a ready-to-operate state,
wherein the bushing has at least one lateral window, through which a key, is insertable into a groove in the insertion section, by means of which the
probe shaft is fixed without play to the loading shaft.
