The bottom rear end of the vertical bar 4 is provided with a first hinge shaft 44, which passes through the first hinge part 36.

[0031] With reference to Figures 1 to 4 When the walker is in use, the fixing part 41 of the vertical bar 4 is located in the accommodating groove 32, and the pin 5 passes through the pair of first pin holes 35 and the second pin hole 42. At this time, the vertical bar 4 is fixed relative to the bottom bar 3. When the pin 5 is pulled out of the first pin holes 35 and the second pin hole 42, the bottom rear end of the vertical bar 4 can rotate around the first hinge shaft 44, thereby completing the folding of the vertical bar 4 and the bottom bar 3. When the walker needs to be used again, the vertical bar 4 is rotated forward. When the vertical bar 4 is rotated forward to the right position, the fixing part 41 is located in the accommodating groove 32, and then the pin 5 passes through the first pin holes 35 and the second pin hole 42.
