These embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0024] Example 1: See Figures 1 to 5 This is the structural view of the utility model. Figure 1A shows a partial enlarged view, a side view, a structural view of the unfolded state, and a structural view of the handrail 4. A multifunctional walker includes a main body 1. Two symmetrically distributed end ear plates 9 are arranged at the end of the main body 1. A back panel 2 is rotatably arranged on the inner side of the end ear plate 9 through a third connecting bolt 15. The back panel 2 is arranged parallel to the main body 1 in the stored state, and the end face of the back panel 2 contacts the end face of the main body 1. A first sleeve is arranged on the outer side of the third connecting bolt 15 and on the inner side of the end ear plate 9. The first sleeve can enable the back panel 2 to better rotate relative to the end ear plate 9. Third limiting bolts 16 are threadedly connected at the third connecting bolts 15 opened on the side walls of both sides of the back panel 2. A third limiting hole is opened on the end ear plate 9 to be plugged into and cooperate with the end of the third limiting bolt 16. When the back panel 2 is in the unfolded state, the third limiting bolt 16 passes through the third limiting hole, and together with the third connecting bolt 15, limits the angle and movement of the back panel 2 to keep it in an upright state.

[0025] A through hole is provided on the inner side of the back plate 2, and a connecting rod 19 is rotatably provided on the inner side of the through hole. Both ends of the connecting rod 19 are threadedly connected to the handrail 4. Two symmetrically distributed threaded holes of the back plate 2 are provided on the end surface of the back plate 2. The inner sides of the threaded holes of the back plate 2 are threadedly connected to the back plate bolts 10. The threaded holes of the back plate 2 are connected to the through holes. A positioning hole 20 is provided on the circumferential surface of the connecting rod 19, which is opposite to the position of the back plate bolt 10. The handrail 4 is an L-shaped structure. The axial direction of the positioning hole 20 is parallel to the long side direction of the handrail 4. The positioning hole 20 is parallel to the back plate bolt 10 are plug-in fit.
