Input: the blue rod to which the red pin is fixed, performing linear reciprocating motion.
Output: green tube performing the following movement: Translate – Rotate - Rotate backward - Translate backward
The yellow nut has a blue pin that moves in the L-shaped slot of the stationary green tube.
The red pin makes the yellow nut rotate and translate.
For this design the yellow nut can rotate under 360 degrees.
