The device wraps the rope so that the other end of the rope moves up and down. The moving rope pulls or lowers the user through a safety belt attached to the user at the end of the rope to help the user stand and walk safely. Although the lifting device of the door frame type walker is simple, since the lifting rope is to bypass the upper beam and then connected to the two winch devices installed in the middle of the two columns, the lifting device and the walking aid are provided. The other parts of the device have to be a whole system. When the user needs to disassemble, especially the height and fatness of the user are different. It is necessary to adjust the height of the column of the door frame walker in time, especially when it is necessary to adjust the width. Moreover, the winch device also occupies a certain use width, which makes the walker wide, and it is inconvenient to use both hands at the same time.
