Claims

[Scope of utility model registration request]

A main body having an opening for receiving the insertion portion of the endoscope at the proximal end and a groove for accommodating a protrusion provided on the endoscope; A rotary ring having a groove provided with a protruding slope, and a biasing means for biasing the rotary ring in one direction with respect to the main body, one end of which is fixed to the main body and the other end of which is fixed to the main body by a locking member. and a plate spring locked to a rotating ring, the rotating ring is rotated against the urging force of the urging means by the plate spring to enable the projection to be inserted, and the projection is inserted to a predetermined position. When it is done,
The urging means rotates the rotary ring to form a connection mechanism for fixing the endoscope, and when the rotary ring rotates, the inner circumferential surface of the leaf spring and the outer circumference of the main body A connecting device for an endoscope, characterized in that the leaf spring is formed in a shape such that it does not come into contact with a surface.
