Statically-indeterminate multifunctional walking stick with variable supporting point

Abstract

The invention discloses a statically-indeterminate multifunctional walking stick with a variable supporting point. The walking stick comprises a connecting table, a pair of holding handles are symmetrically arranged at the upper end of the connecting table, the holding handles are connected with the connecting table through a four-bar mechanism, a first main rod is fixedly connected to the lower end of the connecting table, a second main rod is sleeved with the first main rod, the second main rod is fixedly sleeved with a first fixing hinge base, a sliding rod is arranged in the second main rod in a sliding mode, the sliding rod is fixedly sleeved with a second fixing hinge base, and the first fixing hinge base is connected with the second fixing hinge base through each two supporting rodswhich are connected in a pivoted mode. According to the walking stick, by means of ingenious combination of hinges, rods and the sliding rod, the supporting point at the tail end of the walking stickcan switch between one degree of freedom and three degrees of freedom, so that an optimal anti-skid stabilizing performance is achieved on both the smooth road surface and the bumpy road surface; thefour-bar mechanism is ingeniously used, the two holding handles are manually adjusted so that the holding handles can be spread to form a horizontal plane, then switching between the holding handlesand the chair surface is achieved, and then a rest area can be provided for people at any time and at any places.
