Push to rotate 180 degrees back and forth

Press and release the yellow button to rotate the violet blade 180 degrees.
A special feature is that the blade rotates clockwise and counter-clockwise in turn (not in the same rotary direction).
The red pin is forced toward the inner barrel cam by a spring (in pink).
The blade rotates during the upward movement of the yellow button under the red spring action. Such fast movement helps the blue pin pass through the X-shaped groove of the cam.
It should be noted that the depth of the cam groove is different. In the last scene of the video: brown corresponds to the deepest place, yellow: the shallowest place. The depth change ensures that the green pin moves in right direction.
