1. A universal joint used to transmit a torque generated by an output/driving shaft on a system where connected and/or a rotary motion in a rotary axis to the output/driving shaft on a different axis and allowing an independent lock of a rotation axis, comprising an inner part, a central ring, and an outer ring having at least one screw hole thereon to be used to connect the output/driving shaft on upper surfaces, an alignment diameter used to connect the output/driving shaft to the universal joint, an alignment hole to provide an alignment of a centre of the inner part on an X axis or a Y axis, comprising
a locking hole to provide a locking of the inner part on the X axis and a third pin and a fourth pin located facing each other in a manner the locking hole is between the third pin and the fourth pin in order to provide a rotation of the inner part on the X axis on an outer surface of the inner part,
a central-lower part and a central-upper part of the central ring wherein the inner part is located between the central-lower part and the central-upper part, and mounted symmetrically to each other,
pin holes located on the central-lower part and on the central-upper part and facing each other, formed on an inner surface of the central-lower part and an inner surface of the central-upper part, and facing each other when the central-lower part and the central-upper part are mounted, wherein the pin holes comprises:
at least one first pin hole providing a rotation of the central ring only on the Y-axis,
at least one second pin hole located opposite the at least one first pin hole,
a fourth pin hole and a third pin hole located inside the third pin and the fourth pin respectively and providing a rotation of a spherical inner part on the X axis,
a first pin connected into the at least one first pin hole and providing the rotation of the central ring only on the Y axis,
an outer-lower part and an outer-upper part of the outer ring, wherein the central ring is placed between the outer-lower part and the outer-upper part and the outer-lower part and the outer-upper part are mounted symmetrically to each other,
the outer-lower part and the outer-upper part comprise, formed on an inner surface of the outer-lower part and an inner surface of the outer-upper part facing each other, facing each other when the outer-lower part and the outer-upper part are mounted,
at least one fifth pin hole,
at least one seventh pin hole placed opposite the at least one fifth pin hole and providing the rotation of the central ring only on the Y axis upon a placement into the first pin,
a sixth pin hole located in a centre of the at least one fifth pin hole and a centre of the at least one seventh pin hole
a first short cap pin placed into the at least one second pin hole upon extending from the at least one fifth pin hole and thus providing the rotation of the central ring on the Y axis,
a second short cap pin placed into the fourth pin hole upon extending from the sixth pin hole and thus providing a locking of the central ring on the Y axis,
after passing the first short cap pin from the at least one second pin hole and the at least one fifth pin hole, a long cap pin passed through the at least one fifth pin hole and placed into the at least one second pin hole and the locking hole and thus providing a locking of the spherical inner part on the X axis.
