A module for adjusting the launch of a includes: a cam plate slidingly moving longitudinally having a first and second catching parts a cap lever rotatably coupled to a rotating shaft formed in parallel with the cam plate movement direction, and having a first protrusion moving while being inserted in the first catching part and a cap arm for catching a protective cap and a collet lever rotatably coupled to the rotating shaft having a second protrusion moving while being inserted in the second catching part and a body arm for catching a lancet body. When the cam plate moves backward to a first point, the collet lever moves backward with respect to the cap lever separating the protective cap from the lancet body. When the cam plate moves backward to a second point, the cap lever and the collet lever rotate so that the lancet body moves forward.
