Claims

[Claims for Utility Model Registration] (a) The center part is formed so that the inner pipe passes through it, and the lower half part is fitted and fixed to the upper end of the outer pipe, and A fixing metal body with a stopper storage chamber formed in its half, and (b) an operating lever integrally formed by bending downward on one side of the stopper plate with a fitting hole for loosely fitting into the inner pipe. The stopper plate is housed in the stopper housing chamber by aligning the fitting hole with the penetration part of the inner pipe, and the operating lever is projected outside the stopper housing chamber, and the stopper plate is fixed in the stopper housing chamber. In addition to being attached and supported so that it can swing freely in position,
The stopper body is arranged so that the stopper plate is constantly pressed downward by a spring, and (c) the lower end of the operating lever of the stopper body has a threaded rod screwed in the direction of the outer peripheral wall of the fixture body. The control lever is provided with a safety stopper screw attached to the body of the fixture, and by rotating the screw to bring the tip of the threaded rod into contact with the outer wall surface of the fixture body, the movement of the operating lever toward the fixture body is restricted. A fixing device for a telescopic pipe, characterized in that it is configured to do so.
