US Patent 8479755 Ambulatory aid

An ambulatory aid is revealed. The ambulatory aid includes a hollow main rod and a hollow support pole connected with each other, and a cushion unit therebetween. The main rod, the hollow support and the cushion unit all have insertion holes, aligned with each other. By insertion pins inserted into the insertion holes, the main rod, the hollow support and the cushion unit are assembled with each other. The structure of the assembly of the main rod, the hollow support and the cushion unit is more firm and tighter. When the ambulatory aid is pressed by a larger pressure, the assembly will not come loose and move around and the unstable walking stick makes the users fall down due to a loss of support.
