A stageless adjusting/locating device for various kinds of sticks enables both right-handed user and left-handed users to conveniently stagelessly adjust the length of a stick. The stick is composed of multiple telescopic fitting tubes including mother fitting tubes and daughter fitting tubes nested
A stageless adjusting/locating device for various kinds of sticks enables both right-handed user and left-handed users to conveniently stagelessly adjust the length of a stick. The stick is composed of multiple telescopic fitting tubes including mother fitting tubes and daughter fitting tubes nested in the mother fitting tubes. The adjusting/locating device is disposed at each of the mother and daughter fitting tubes. The adjusting/locating device includes a screw member formed by a threaded rod having outer threads and a locking member composed of two semicylindrical bodies mating with the threaded rod. A fastening ring is fixedly fitted around the locking member. The inner circumferential faces of the two semicylindrical bodies are formed with inner threads. An upper and a lower end of the inner threads are formed with thick sections converging from thin sections. The inner wall faces of the thick sections are formed with semielliptic arch faces. By rotating the daughter fitting tube in either a clockwise or a counterclockwise direction, the screw member is simultaneously rotated to expand the locking member so as to tightly abut against the inner circumferential face of the mother fitting tube and thus easily and reliably achieve an adjustment.
