Can you please suggest what kind (type) of hinge / pins I should use to make the mechanism in the attached file. I was considering to use the pins shown in the second image. But I am not sure if it will work.

1$\begingroup$ it would depend on many things such as materals , load , how many cycles do you need it to last, etc, etc. $\endgroup$– agentpCommented Nov 3, 2017 at 17:20

$\begingroup$ correct. I will keep that in mind. But what kind of pin / hinge is shown in the red circle (in the above image)? What is it called? $\endgroup$– Rutvij KotechaCommented Nov 3, 2017 at 18:31

What is shown in the picture is what people usually refer to as a pin connection. There are multiple ways you can design a pin connection as suggested in the comments above and there is no one right design for it. Disregarding practical considerations, such as materials, load cycles and etc, and in pure design engineering terms, you will need to find the shear strength of the items you have selected for your pin, and make sure it is reasonably stronger than what you have calculated for the shear load on the pin based on the configuration you have. The shear load on the pin can be determined from the normal force at the pin connection, and ut can be something less if you have double shear or triple shear mechanisms in your pin connection in question.
