摘要

The arm has a left sided curved and spring mounted pressure plate (712) and a right sided curved and spring mounted pressure plate (713) that are mounted between a securing nut (711) and a main support arm. Another two plates are mounted between another nut and the support arm, where clamping effect is created by reactional forces after securing the plates. A nut is moved forward to a spring, so that the spring is under tension.
