When the endoscope is used, the bending angle needs to be locked at any time so as to enable the probe to fixedly observe a target object from an optimal angle. In the prior art, an endoscope is generally provided with a bent angle locking mechanism and an unlocking mechanism in a bent angle operating system. The bent angle is locked through the bent angle locking mechanism, and is operated after being unlocked. In this way, although the use requirements can be met, in practical use, when one hand holds the endoscope and manipulates the corner to find the target object, the other hand is required to operate the corner locking mechanism to fix the observation. The problem is that not only does one more operation be required to manipulate the corner lock mechanism, but the probe may shake during this time to affect the view, but the other hand is occupied, thereby affecting the other necessary operation. Therefore, the bending angle can stop along with bending without deliberately unlocking and locking according to the operation requirement and the humanization of the operation.
In the solution, one is to arrange a bending damping device in the bending control system, so that the bending can stop along with bending, but the defect is that when the bending is controlled, fingers are required to overcome bending force and bending damping force, so that the bending control force is increased, and the fingers are easy to fatigue after long-time use.
