• a supporting part;
• a sleeve grip part mounted on the supporting part to hold and support the tube;
• a fiber chucking part movably mounted on the supporting part, supporting the fiber of the tube assembly, and moving toward and away from the sleeve grip part in a direction parallel to an axis of the tube and by specified distances;
• and
• a lift unit mounted on the supporting part to control the fiber chucking part to move in the direction with respect to the sleeve grip part to allow the tube assembly to be disposed within the tube,
• wherein the lift unit comprises:
• a lifting block movably mounted on the supporting part to be coupled to the fiber chucking part;
