Provided is a telescopic device that includes a first shaft telescopically coupled to a second shaft. The first shaft defines a hole and an orifice. The second shaft defines a plurality of engaging portions. The second shaft inserts in the hole. The second shaft is movable with respect to the first shaft to a position in which one of the plurality of engaging portions is aligned with the orifice.A positioning device is coupled to the first and the second shafts. The positioning device includes a control being movable and a fastener being movable actuated by the control. The fastener is movable with respect to the control. The fastener inserts and is movable in the orifice. The first shaft is adapted to be unmovably positioned with respect to the second shaft at various positions by the positioning device.
本发明提供一种伸缩工具,包括第一杆件、第二杆件以及定位装置。第一杆件具有贯孔与连通贯孔的第一定位孔。第二杆件可移动地穿设于贯孔并具有复数第二定位孔,任一第二定位孔能够对齐第一定位孔。定位装置包括切控导件与定位件。切控导件能够相对第一杆件移动并可移动地连接于定位件。定位件可移动地穿设于第一定位孔并随切控导件相对第一杆件移动而可脱离地卡接于复数第二定位孔中任一第二定位孔,以使第二杆件能够选择性地相对第一杆件移动。
