Description

  The present invention relates to a cane, and more particularly, to an anti-rotation telescopic cane having a novel structure.

  In order to adapt the cane used as an auxiliary tool during walking to various heights of the user, those skilled in the art have developed a telescopic cane that can be adjusted in length. A conventional telescopic cane usually adjusts the length of the cane by the following method or a method similar to that method. That is, the outer wall of the second support column is provided with a positioning pin that protrudes in the radial direction and has elasticity, and a plurality of positioning holes along the radial direction are provided at predetermined positions on the inner wall of the first support column corresponding to the positioning pin. Provide. The 2nd support | pillar is inserted in the 1st support | pillar, and the several positioning hole is arrange | positioned at the inner wall of the 1st support | pillar along the straight line at intervals. Therefore, the length of the cane is adjusted by coupling the positioning pins to different positioning holes. For example, the length of the cane is adjusted by the above-described method even in the Chinese utility model in which the inventor has previously filed the application number 200820234848.0 and the name of the device is “foldable cane that can be adjusted in length”. To do. However, since the cane support column is almost cylindrical, when the length of the cane is adjusted by the method described above, relative rotation is likely to occur between the first support column and the second support column. When adjusting the length of the cane, if there is a relative rotation between the first strut and the second strut, the positioning pin of the second strut cannot be easily coupled to the positioning hole of the first strut. . In addition, since there are many elderly people who cannot move freely, it becomes more difficult to connect the positioning pins to the positioning holes, which affects the convenience of the cane.

  The inventor has invented the present invention that can solve the above-mentioned problems based on years of experience in manufacturing, developing and designing related products.
