1results about How to "Adjustable friction" patented technology

This invention discloses an endoscope. The endoscope includes an endoscope body, a handwheel structure, and a damping structure. The endoscope body includes a housing and a curved portion located at the front end of the housing; the handwheel structure is rotatably mounted on the housing and connected to the curved portion; the damping structure is located inside the housing and has a damping surface that forms a frictional engagement with the handwheel structure; the handwheel structure can rotate relative to the housing under external force to adjust the bending angle of the curved portion; when the external force on the handwheel structure is removed, the frictional engagement between the damping surface and the handwheel structure restricts the rotation of the handwheel structure relative to the housing; the damping structure can move relative to the housing under external force to adjust the frictional force formed between the damping surface and the outer peripheral surface of the handwheel structure. This invention makes the handwheel structure less prone to jamming and smoother during use, and also prevents it from rotating arbitrarily, thus better ensuring operational stability and improving the user experience.
