[Action]

 The present invention provides an adjustable-length cane having the above-described configuration. At least a narrow groove is provided around the entire inner wall of the upper tube of the cane formed of two upper and lower tubes, and the same type of product is used. In comparison, the force of the stopper (locking force) of 75% to 85% (compared to our company) can be improved.

[0006] The improvement of the locking and holding force is achieved by using a screw body having a conical surface and a screw shaft integrally protruded at the upper end of the lower pipe of the upper and lower two pipes constituting the cane pipe. In addition to being fitted and movably inserted up and down, a cylindrical braking locking member having expansion elasticity in all circumferential directions is fitted and inserted into the screw shaft portion by vertically dividing grooves provided from above and below in the longitudinal direction. The braking member has a conical surface and is fitted with a child braking locking member provided with a vertically split groove from above, and is screwed to the screw shaft. This is done with the upper pipe installed. In other words, when the lower pipe is lifted upward, the screw body rises and the conical surface of the body expands the vertically dividing groove of the braking locking member, and the inner surface of the upper pipe, which has a narrow groove all around its inner circumference, The brake locking member is pressed and locked. Further, since the conical surface of the child brake engaging member also expands the vertical groove of the brake engaging member, the brake engaging member is pressed and locked on the inner surface narrow groove portion of the upper pipe on almost the entire peripheral surface.
