HANDLE BENDING CONTROL AND LOCKING MECHANISM, ENDOSCOPE HANDLE AND ENDOSCOPE SYSTEM

A handle bending control and locking mechanism, an endoscope handle, and an endoscope system. The handle bending control and locking mechanism comprises a fixed shaft (40), a knob assembly (30), a limiting assembly, and an elastic member; the fixed shaft (40) is configured to be mounted on a handle body (10); the knob assembly (30) is movably sleeved on the fixed shaft (40) and is connected to a bending control assembly, such that when the knob assembly (30) rotates, the bending control assembly is driven to move, and the distal end of an insertion tube (20) bends by means of the movement of the bending control assembly; the elastic member is arranged in contact with the knob assembly (30); the limiting assembly is sleeved on the fixed shaft (40), and at least part of the limiting assembly can move along the axial direction of the fixed shaft (40) to press on the knob assembly (30) and the elastic member, causing the elastic member to lock the rotation of the knob assembly (30).
