1. A colon linearizing device installed in an endoscope to linearize a colon by performing translation and expansion motions in the colon, the colon linearizing device comprising:
a ring-shaped proximal member installed to surround an outer circumferential surface of an insertion tube of an endoscope;
a fixed end secured to the insertion tube;
a ring-shaped distal member positioned between the proximal member and the fixed end and movably installed along a longitudinal direction of the insertion tube;
an elastic member connected between the fixed end and the distal member;
a translation drive device to translate the distal member, wherein the translation drive device includes a base and a driving block; and
an expansion drive device to expand the distal member or the proximal member by supplying air pressure to the distal member or the proximal member, wherein the expansion drive device includes an air tube,
wherein, the translation drive device translates the distal member to approach the proximal member by providing power to the distal member, and
when the translation drive device does not provide power to the distal member, the distal member is translated in a direction toward the fixed end by the elastic restoring force of the elastic member.
