A cane is used as a walking aid, and FIG. 1A shows a conventional cane 1 having a pipe body 2 with a grip 3 attached to the upper side for grasping by a user. The grip 3 is assembled to the pipe body 2 through a clamp joint 4, the clamp joint 4 being a substantially C-shaped ferrule having an opening 5 with side pieces 6 on either side of the opening 5, respectively. Each side piece 6 is provided with a through hole (not shown), the clamp fitting 4 fits the pipe body 2, and a bolt 7 extends through the through hole of the two side pieces 6. Further, the two side pieces 6 are tightened with nuts 8, and the two side pieces 6 hold and position the pipe body 2. As shown in FIG. The conventional grip 3 cannot be stably positioned because the method of assembling the clamp joint 4 to the pipe body 2 with the bolt 7 and the nut 8 is not stable. Having to drill the through holes on the coupling 4 makes the manufacture and processing of the clamp coupling 4 difficult.

FIG. 1B shows another conventional cane 1', which also comprises a pipe body 2 and a grip 3, said pipe body 2 being fitted with an inner pipe 21 and an outer pipe 22 to extend and retract in length. It can be adjusted freely. The grip 3 has a fitting member 9 fitted to the pipe body 2 and fixed with a rivet 91 . The grip 3 of such a cane 1' is fixed with a rivet 91, and the position of the grip 3 cannot be adjusted, and the rivet 91 is inserted into the pipe body 2. It restricted and affected the elastic state of the
