ABSTRACT:
A mounting device for accessories of endoscope oculars comprises a mount body having a central through hole and a hollow cylindrical rim secured to one end of the body. Within the rim there is provided a cavity in the form of a truncated cone for receiving an ocular of an endoscope. Plate cams are rockably supported in axially elongated slits formed in the rim. The plate cams are urged by springs stretched between them and the rim, and their inner faces can contact an ocular inserted in the cavity so loosely that the ocular may be rotated. About the rim a fixing cam ring and a release cam ring are provided rotatably with respect to the mount body. The inner periphery of the fixing cam ring provides such cam surfaces that the fixing cam ring causes the inner faces of the plate cams to push the rear face of the ocular thereby to connecting the ocular immovably to the mounting body when it is rotated in one circumferential direction. The inner periphery of the release cam ring provides such cam surfaces that the release cam ring moves the plate cams from the passage of the ocular when it is rotated in one circumferential direction. When both cam rings are selectively rotated, the ocular is connected immovably to the mounting body, can be rotated with respect to the body or can be disconnected from the body. Therefore, the ocular can be connected to, and disconnected from, the mounting body both easily and unfailingly.
