Claims

[Claims for Utility Model Registration] ■ A telescoping rod 4 is constructed by screwing a screw shaft 3 into a cylinder 2 having a fitting 1 for connecting to the shaft at the top so as to be relatively rotatable, and the screw shaft 3 The slider 5 has a slider 5 connected to the end thereof so as to be able to move integrally in the axial direction, and a base plate 6 at one end. A tubular body 7 is externally fitted onto the rider 5 so as to be relatively movable in the axial direction, and serrated engagement portions are formed on the periphery of the slider 5 at appropriate intervals along the sliding direction. The structure of the telescopic support rod for construction and construction is configured to be extendable and fixed in multiple stages through stoppers 9 and - attached to the pipe body 7 side so as to be elastically engaged, and the slider 5 is connected to the pipe. A part of the peripheral wall of this pipe slider 5 is crushed over the entire length in the axial direction to form a protrusion 5A, and the above-mentioned serrated engagement part 8 is formed on the top 5B of the protrusion 5A. A structure of an extensible support rod for architecture and construction, characterized by having a notch formed therein. (2) The construction according to item (2) of the utility model registration claim, wherein the top portion 5B of the protrusion 5A is formed from two edges 5b, 5b created by cutting off the bent connecting portion 5C by crushing. Structure of telescopic support rod for construction.
