Title:
PIPE-FIXING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/026760
Kind Code:
A2
Abstract:
The present invention relates to a pipe-fixing device, which firmly fixes an outer pipe fitted onto an inner pipe so as to achieve a desired length when the outer pipe is fitted onto the inner pipe and a fitting length is adjusted so as to form a long rod, for example for mountain-climbing sticks or a mop. The pipe-fixing device of the present invention has a collet for fixing a pipe, wherein the collet tightly contacts the outer surface of the pipe over an area that is wider than that of a conventional collet, thus more easily and firmly fixing the pipe at a desired point. A portion of the pipe-fixing device which is contacted by second collet pieces of a movable collet, and a portion of the pipe-fixing device which is contacted by first collet pieces of a fixed collet are slightly spaced apart from each other such that a twist of one of the aforementioned two portions occurring in one direction may be compensated for by the twist of the other in the opposite direction, and a firmly fixed state of the pipe may be maintained even when a twist occurs or an impact is applied in a lateral direction and not in a vertical direction.
