The joints constraint

VC has plug-ins that have no joint constraints. Some expressions are difficult to write. Can you share them?

I hope somebody share it,too

What do you actualy want to see?

Can you give an example of a plug-in with no joint constraint?

Hi
I made a case and took a long time to calculate this formula. Is there any similar constraint to directly achieve this linkage effect?

Link_1:主动关节
Link_2:Link_1带比例的从动关节
-VALUE
Link_3:Link_1带比例的从动关节
Rz(-asind(sind(J1)*19.5/140))
Link_4:Link_1带比例的从动关节
Ty(cosd(J1)19.5+sqrt(140140pow(sind(J1)*19.5,2))-159.5)

Thank you!
