Abstract
PURPOSE:To draw an operating wire to a sufficient length by a small-scale lightweight apparatus, by providing the cam formed into an oval shape whose longitudinal direction is an operating wire draw-out direction and fixed to an operating part and moving a connection piece along the cam when a drive piece is revolved. CONSTITUTION:The operating wire 22 mounted to the tip of a curved part 2 at one end thereof is drawn by revolving an operating lever 6 to bend the curved part 2. The connection arm 25a on a pull side revolves along a cam 23 and the contact point thereof with the cam 23 gradually moves toward the long diameter part of the cam 23 and the connection arm 25a is moved while outwardly opened by the cam 23. Therefore, a wire stopping pin 27 moves from a point A to a point C and the operating wire 22 is largely drawn. As mentioned above, the stroke of the operating wire 22 can be largely increased by a small apparatus and, by changing the shape of the cam 23, the increase degree of the stroke can be appropriately set.
