1. A delivery device, comprising:
a main body; a holder for housing and holding a container, wherein said holder is configured to axially fix the container within said main body; a spring biased plunger; a cylindrical part comprising an inner surface that is directly operatively in contact with said plunger; a spring biased needle shield unit slidably arranged along an inner surface of said main body, said needle shield unit slidably engaged along at least a portion of said cylindrical part; wherein when said needle shield unit is activated during an injection step; said interaction between said spring biased needle shield unit and said cylindrical part causes said cylindrical part to rotate from a first position to a second position, thereby allowing said plunger to move under a force of a tensioned injection spring.
