る。2. Description of the Related Art Clamps for telescopic rods are mainly used for telescopic rods that include an expandable inner tube and an outer tube, such as an elastic clothes rack, and the inner tube is usually attached to the end of the outer tube. It is designed to be clamped and positioned by the clamps provided.
Further, as shown in FIG. 6, the structure of the conventional telescopic rod clamp mainly has an annular clamp body (61), and a through hole (a nut (62) is embedded therein at one side thereof ( 611) is provided, and in the through hole (611),
A bolt (63) having a rotating member (631) at one end is screwed so as to extend outward. When the clamp is used, for example, on a telescopic rod for hanging clothes, the inner pipe (5
The annular clamp body (61) is fixed to the end of the outer tube (51) in which 2) is inserted, and the inner tube (52) is extended to a desired length, and then the rotating member (631). The inner tube (52) is fastened and positioned by rotating the inner tube (52) by appropriately rotating the outer tube (52) with the end of the bolt (63).

あった。However, the fastening force to the inner pipe in the above-mentioned conventional clamp is due to the clamping force between the bolt screwed on the clamp body and the annular clamp body, and the load applied to the inner pipe. The larger the value, the stronger the clamping force to the inner tube, so the surface of the inner tube is likely to be damaged, and in the case of an inner tube with a thin wall, the inner tube is further deformed and smoothed inside the outer tube. There was a problem that it could not be expanded or contracted.
