1. An exoskeleton for supporting an arm of a user, comprising:
a torso attachment device for releasably connecting the exoskeleton to a torso of the user;
a bracket which is connectable to the torso attachment device;
a lifting rod which is connectable to the torso attachment device via the bracket and which is reversibly movable in a first direction and a second direction relative to the bracket;
a cantilever for supporting the arm of the user which is releasably connectable to the arm of the user;
a ratchet mechanism, wherein the ratchet mechanism connects a first end of the lifting rod to a first end of the cantilever; and
a blocking device, wherein the ratchet mechanism is adjustable by the blocking device from a release position into a blocking position, wherein in the release position the cantilever is pivotable relative to the lifting rod about an axis of rotation in a first direction of rotation and in a second direction of rotation, wherein in the blocking position of the cantilever is blocked from being pivotable relative to the lifting rod is blocked in the second direction of rotation but not in the first direction of rotation, and wherein, when pivoting the cantilever in the first direction of rotation, the lifting rod is moved in an upward direction, and, when pivoting the cantilever in the second direction of rotation, the lifting rod is moved in a downward direction.
