Claims

[Scope of utility model registration request]

In a device consisting of an outer diameter pipe, an inner diameter pipe inscribed therein and movable in the axial direction, and a connecting ring portion that restrains movement of the inner diameter pipe, the connecting pipe portion is:
A wedge ring fixed to one end of the outer diameter pipe, a presser body movable in the axial direction adjacent to the wedge ring, and the wedge ring has a wedge-shaped slope portion that opens on the side of the presser body that faces the presser body. A stopper body that circumscribes the inner diameter pipe and moves in the axial direction is installed between the slope part and the presser body, and one end of the connecting pipe part is connected to the outer diameter pipe,
The other end is covered with a connecting tube that circumscribes the inner diameter tube, and this connecting tube is axially biased against the outer diameter tube in opposite directions by a spring body A and a spring body B, and the spring body A
comes into contact with the presser body and urges the stopper body toward the sloped part, and the connecting pipe has a stepped part that comes into contact with the presser body, so that when the connecting pipe is moved toward the opening side of the sloped part, the presser body is pressed against the slope part. A telescopic extension tube for a vacuum cleaner, characterized in that the body also moves as one.
