To provide a golf stretchable rod capable of adjusting expansion and shrinkage and preventing relative rotation occurring between pipes.SOLUTION: The gantry extension rod comprises an outer tube 10 assembled in order from the outside to the inside, a middle tube 20 and an inner tube 30, a first cutting portion 40 is joined between the outer tube 10 and the inner tube 20, A second cut portion 50 is joined between the middle tube 20 and the inner tube 30. By assembling the first cutting portion 40 and the second cutting portion 50, the outer tube 10, the middle tube 20 and the inner tube 30 are limited so as not to cause relative rotation under normal conditions, and the outer tube 10, the middle tube 20 After completion of adjustment of expansion and contraction of the inner tube 30, the middle tube 20 and the inner tube 30 are tightly localized by operating the first cut portion 40 and the second cut portion 50.(FIG.【課題】伸縮調整ができて、各管間で起きる相対回転を防止できる園芸用伸縮竿を提供する。【解決手段】園芸用伸縮竿は、外側から内側へ順番に組み立てる外管10、中管20と内管30を含み、外管10と中管20の間に第一切断部分40が接合され、中管20と内管30の間に第二切断部分50が接合される。該第一切断部分40と第二切断部分50の組み立てによって外管10、中管20と内管30が常態下において相対的な回転が生じないように制限され、外管10、中管20と内管30の伸縮調整が完成された後、第一切断部分40と第二切断部分50の操作によって、中管20と内管30が緊束定位される。【選択図】図2
