Adjustable cane with memory function

摘要

A cane includes a tube (11), an extension rod (12) telescopically mounted within one end of the tube (11), and a control mechanism (2) sandwiched between the tube (11) and the extension rod (12). The tube (11) defines a first aperture (111) and a second aperture (112). The extension rod (12) defines a plurality of holes (14). The control mechanism (2) is movable among a first position where the control mechanism (2) is positioned in a selected one of the holes (14) in the extension rod (12), and the tube(11), the extension rod (12) and the control mechanism (2) are prohibited from moving axially with respect to one another; a second position where the extension rod (12) and the control mechanism (2) together are allowed to move axially with respect to the tube (11); and a third position where the extension rod (12) is allowed to move axially with respect to the control mechanism (2) and the tube (11).
