Claims

[Scope of utility model registration request]

An outer pipe 2, an inner pipe 3 slidably inserted into the outer pipe 2, and a circular spring fitting part 6 fixed to one end of the inner pipe 3 in the outer pipe 2 in a protruding manner. It is composed of a locking member 4 and a circular spring 11 that is fitted over a fitting part 6 of the locking member 4, and the central axis P2 of the fitting part 6 of the locking member 4 is the central axis P of the inner pipe 3.
An outer convex portion 8 is provided on one half of the outer periphery of the fitting portion 6 and gradually protrudes outward in the circumferential direction. An inward protrusion 13 is provided on the other half of the circumference and gradually protrudes inward in the circumferential direction, and when the outer via "2" and the inner pipe 3 are extended, the locking member 4 is attached to the inner pipe 3.
However, the fitting portion 6 and the outer convex portion 8 rotate the occluded circular spring 11 so as to push it open from the inside, and the outer surface of the occluded circular spring 11 is brought into pressure contact with the inner surface of the outer pipe 2. A locking device for a telescopic pipe, in which an outer pipe 2 and an inner pipe 3 are connected to each other.
