Inversions of the mechanism: A mechanism is one in which is fixed one of the links of a kinematic chain. Different mechanisms can be obtained by fixing different links of the same kinematic chain. These are called as mechanism reversal. By changing the fixed link, the number of mechanisms that can be obtained is equal to the number of links. Except for the original mechanism, all other mechanisms will be known as inversion of the original mechanism. The inversion of a mechanism does not change the movement of its bonds with each other.
A four-bar link, also called a four-bar link, is the simplest moving closed chain link. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so that the links move in parallel planes, and the assembly is called a four-bar plane link.
If the joint has four hinged joints with inclined axes to intersect at a single point, then the links move over concentric spheres and the assembly is called the four-spherical spherical link. The Bennett link is a four-bar space link with hinged joints that have their axes tilted in a particular way that causes the system to move.
It can be understood in the following video:
