A rotary telescopic crutch comprises a shoulder and hand connecting rod (1), a manual rotating lock rod (2), a hand holding rod (3), a telescopic rod slide rail (4), a manual adjusting lock (5), a telescopic rod (6) and a shoulder support rod (7). One end of the shoulder and hand connecting rod (1) is connected with the shoulder support rod (7), and the other end thereof is rotatablely connected with the hand holding rod (3) through the manual rotating lock rod (2). One end of the telescopic rod slide rail (4) is connected with the hand holding rod (3), and the other end thereof is connected with the manual adjusting lock (5). The telescopic rod (6) is provided in the telescopic rod slide rail (4) and slidingly connected with the telescopic rod slide rail (4). A locating lock hole (8) is provided on the telescopic rod (6), and the manual adjusting lock (5) is matched with the locating lock hole (8) so as to fix the telescopic rod (6) in the telescopic rod slide rail (4). The shoulder and hand connecting rod (1) of the rotary telescopic crutch can be rotatablely folded with the manual rotating lock rod (2) as an axis, and the telescopic rod (6) can also achieve the effect of contraction through the telescopic rod slide rail (4), so that the whole length of the crutch can be further shortened, and the crutch is convenient to carry.La présente invention concerne une béquille télescopique rotative comprenant une tige reliant la main à lépaule (1), une tige de verrouillage rotatif manuel (2), une tige de tenue en main (3), un rail coulissant (4) de tige télescopique, un mécanisme de verrouillage (5) du réglage manuel, une tige télescopique (6) et une tige de support de lépaule (7).
