PURPOSE: An extension controlling device of a multi-stage stick for climbing is provided to obtain excellent assembling properties due to quick and accurate assembly, and to prevent the abrasion to the outer circumferential surface of a lifting cap. CONSTITUTION: An extension controlling device of a multi-stage stick for climbing includes a half-pressing body(101), connecting members(102), a lifting cap(111), and a supporting plate(123). A half-slope and a first slot are formed at the upper side inside the half-pressing body. The half-slope is perpendicular to the first slot. A half-threaded part is formed at the lower side inside the half-pressing body. The connecting members connect the both lower sides of a pair of half-pressing bodies so that the half-pressing bodies can surround the threaded rod of an inner connecting pipe. The lifting cap has a connecting hole and a second slot. A connecting rod on the threaded rod is loosely coupled to the connecting hole, and the top side of the lifting cap is restrained by the latching protrusion of the connecting rod. The supporting plate for supporting the bottom side of the lifting cap is formed at the lower side of the connecting rod. |
