Kinematics for Clamps

[Speedy]

Can anyone help in defining kinematics for the Clamps, the problem is that I am unable ti define the real kinematics to the clamp and as a result the clamp fouling with the gun during the gun movement I cannot check it properly. The basic of kinematics I cannot apply in this case as I cannot replicate the true motion of the Clamp parts... Maybe I can upload the picture the next time so that it gets clear and some one can help over it.............  I had tried this many times but failed to do so  Please come back who ever knows it.........

we need the picture and the *.co or *.rf of the clamp
