Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a telescopic pipe device being easy to be held fixed and released in a desired telescopic position. SOLUTION: When the length of a telescopic pipe is varied to a predetermined length, the lock means of a support mechanism fixes a cylinder spring member in position against a load applied to the telescopic pipe along one direction, e.g., a load applied to the cylinder spring member by the weight of an end tool, an object attached to the end tool, and the telescopic pipe, so that the telescopic pipe can be fixed in position against the load applied to the telescopic pipe. Since the lock means can be released by a releasing means, the direction in which the load is applied to the cylinder spring member can be varied, whereby the telescopic pipe can be freely extended or contracted. |
