A deformable variable helical cylinder of the present invention is fundamentally based on a helix in a space. A helix starts at a point in a space and rotates around a central axis to draw a trajectory, and has a similar shape to a common spring. The factors defining a helix are the radius, pitch, and height of the helix. A variable helix is a helix of which the radius and period are modified, and in the present invention, the variable helix is characterized by a form in which the radius at the lower end thereof decreases toward the top. A deformable variable helix (mVHC) is a variable helix that is deformed once further, and the biggest feature thereof is that the exit section of the variable helix is deformed to be almost parallel to the central axis of rotation.
