Claims

[Scope of utility model registration request]

A first feeding rod is formed with a main pipe member having a fitting portion at its tip, and has an outer diameter that freely slides into the fitting portion of the main pipe material, and has a fitting portion at its tip. and fixing a first elastic interference annular frame made of a thin steel plate material or an equivalent elastic plate material with a split elastic bulging piece larger than the inner diameter of the main pipe material at the rear end of the first feeding rod. Then, the first feeding rod is pushed into the main pipe material so that the tip of the first feeding rod is slidably fitted into the fitting part of the main pipe material, and the fitting part of the first feeding rod is fitted into the fitting part of the main pipe material. facing outward from the outside,
The first elastic interference annular frame is fitted inside the rear end of the main pipe material, and the first elastic interference annular frame is slidably fitted into the fitting part of the first feeding rod so that the tip thereof faces outside of the fitting part. Insert the second feeding rod into the first feeding rod,
A second elastic interference annular frame having the same configuration as the first elastic interference annular frame fixed to the rear end of the second feeding rod, and having split elastic bulging pieces having a diameter larger than the inner diameter of the first feeding rod. A general-purpose telescopic rod that is fitted into the first feeding rod.
