Zusammenfassung:	The utility model provides a novel rotation bending mechanism. The novel rotation bending mechanism is mainly composed of connecting bodies, connecting blocks, connecting pins, fixing pins and the like. Each connecting body is connected with the corresponding connecting block together through the corresponding connecting pin to form a single connecting piece similar to a cross shaft coupler, each connecting piece can be rotated by 1 degree to 2 degrees, and the multiple connecting pieces can achieve large-angle bending. After being applied to a flexible short section, the novel rotation bending mechanism plays a very important role in the serious-corrosion or great-bending oil well use process of instruments and particularly plays a very important role in the horizontal well logging process.
