1. A sampling device of acquiring a graphite sample from a reactor graphite block, comprising:
a support placed on the reactor graphite block;
a lifter configured to be insertable into the reactor graphite block in a first direction; and
a sampling actuator arranged at an end of the lifter and configured to acquire a graphite sample from the reactor graphite block,
wherein the sampling actuator is configured to insert into the reactor graphite block in a second direction, and the first direction is substantially perpendicular to the second direction,
wherein a caster is installed at a bottom of the support to move the support on the reactor graphite block, so that the lifter is aligned with a sampling position of the reactor graphite block.
