Link 1 slides along axis x-x in fixed guide p and is connected by sliding pair A to link 3. Link 2 is connected by sliding pair B to link 3 and slides along axis y-y in fixed guide q. When link 1 has straight translational motion along axis x-x, link 2 has straight translational motion along axis y-y. Axes x-x and y-y intersect in space.
