Abstract: A self-locking angle adjustment mechanism for an endoscope includes: an endoscope angle adjustment steel wire (5), a rotation handle (2), an endoscope handle (3) and a self-locking rotation device, wherein: an outer conical surface is provided at an external surface of the rotation shaft (7), a conical cylinder is sleeved onto the outer conical surface; a spring (14), which is capable of driving the rotation shaft to move towards a direction of the conical cylinder or driving the conical cylinder to move towards a direction of the rotation shaft, and forcing the inner conical surface to closely fit with the outer conical surface for self-locking, is located along an axial direction of the rotation shaft or conical cylinder. Through the present invention, the flexible sheath is locked stepless at any position, meeting free positioning requirement of endoscope during surgeries, reducing labor strength during surgeries, avoiding patient injuries caused by misoperations.
