Locking Device for Endoscope, Endoscope, and Locking Device

An endoscope, comprising a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc driving assembly;

• wherein
• the first rotating wheel is coupled to a first end of the first rotating shaft;
• a first traction disk is provided around the first rotating shaft at a position close to a second end of the first rotating shaft;
• wherein the first rotating shaft is controlled by the first rotating wheel to rotate, and in turn drives the first traction disk to rotate;
• and
• the brake disc is arranged on at least one side of an outer circumferential surface of the first rotating shaft or an outer circumferential surface of the first traction disk;
• a tightness of engagement between the brake disc and the outer circumferential surface of the first rotating shaft or the outer circumferential surface of the first traction disk may be adjusted by the brake disc driving assembly, such that a rotational damping on the first rotating shaft may fall within a first preset damping range;
• wherein a first traction wire may be adjusted via the rotation of the first traction disk, thereby adjusting a viewing angle of the endoscope in a first dimension;
• with such an adjustment and the damping provided by the brake disc, the lens of the endoscope can be driven to rotate into a required viewing angle in the first dimension and stay there as needed.

A locking device, comprising a first rotating wheel, a first rotating shaft, a brake disc, and a brake disc driving assembly;

• wherein
• the first rotating wheel is coupled to a first end of the first rotating shaft;
• a first functional disc is provided around the first rotating shaft at a position close to a second end of the first rotating shaft;
• wherein the first rotating shaft is controlled by the first rotating wheel to rotate, and in turn drives the first functional disc to rotate;
• and
• the brake disc is arranged on at least one side of an outer circumferential surface of the first rotating shaft or an outer circumferential surface of the first functional disc;
• a tightness of engagement between the brake disc and the outer circumferential surface of the first rotating shaft or the outer circumferential surface of the first functional disc may be adjusted by the brake disc driving assembly, such that a rotational damping on the first rotating shaft may fall within a first preset damping range.
