It includes a compression spring 6v for separating the roller m and the sliding body 6t, and a tooth plate 6W provided integrally with the sliding body 6t and facing the gear 6q. The tip side 5C of the first connecting member 5a is attached to the sliding body 6t, and the second connecting member 5d
The proximal side 5f of each is connected to the endless winding medium 6p. In this way, even if the large-diameter pipe 2a and the small-diameter pipe 2b are expanded and contracted, the endless wrapping medium 6p only rotates, and the connecting means 5 can also be expanded and contracted. The large-diameter pipe 2a and the small-diameter pipe 2b are connected by the clamp means 2C, and the operating lever 3 is operated to pull the first connecting member 5a (and the sliding body 6t also moves backward (to the right in FIG. 6)). The tooth plate 6 is pulled against the tension of the compression spring 6VIF.
W meshes with the gear 6q and restricts rotation of the gear 6q (see Fig. 9). Therefore, the operation of the operating lever 3 is transmitted to the second connecting member 5d via the connecting means 5, and the opening/closing tool 4 is opened and closed.
