- a counterpart with internal thread or mating thread is provided for the shaft with the external thread.
- a rope is already threaded through the Ka ⁇ nal, wound around the external thread of the shaft and can still be tightened by the counterpart.
- the tendon is released.
- the threads of the shaft and the counterpart can engage each other. By engaging the threads into each other, a force acts on the tendon. The tendon is clamped and held. Otherwise, by Auseinan ⁇ derrage or sliding apart of the threads from each other, the holding force is reduced. The tendon is relieved or loosened.
- the at least one external thread is arranged on an end region of the shaft.
- the external thread is attached, in particular facing the head end of the ⁇ accordingly. This area has proven to be particularly advantageous in terms of stability and reliability of attachment.
- the shaft has two external threads, which are arranged at opposite end regions of the shaft. Accordingly, a second external thread is provided in addition to the first external thread.
- the first external thread serves to fix the tendon.
- the second external thread serves to attach the tendon to any unit, such as joint unit or on ⁇ drive unit. This allows advertising beneficial ⁇ way legally used flexibly in any system the fixing unit to.
- the two external threads differ in their diameters from each other. Accordingly, the diameter of the first external thread is greater than the diameter of the second external thread.
- other diameters can be chosen flexibly. For example, the larger diameter can be used as a stop.
- the fastening unit is at least partially produced by a 3D print. Accordingly ⁇ speaking part of the mounting unit or the ge ⁇ entire mounting unit is built layer by layer by means of 3D printing on ⁇ .
- the 3D printing allows in particular a fast production.
