Endoscope curving mechanism and endoscope bending device

The invention discloses an endoscope curving mechanism and an endoscope bending device. According to the endoscope curving mechanism disclosed by the invention, a first adapter rotates to drive a rotating wheel to rotate in a first mounting housing, and a first adjusting rope or a second adjusting rope is rolled by the rotating wheel, so that rope length differences between the first adjusting rope and the second adjusting rope are formed, and the operation of buckling is performed on an inserting part; the curving structure and the first adapter are located in the first mounting housing, andthe first mounting housing is detachably connected with a second mounting housing, so that the curving part and the control part in the endoscope bending device are completely separated to form two independent structures; and therefore, after the endoscope bending device is used, the curving part can be independently replaced only through separating the first mounting housing from the second mounting housing, a part of st
