Abstract
A tetraxial-link artificial limb joint includes a kneecap, front connection boards, a rear connection rod, a first axis, a second axis, a third axis, a fourth axis, and a shank connection seat. The point for force acting is below these four axes, thereby forming an inverse triangular therebetween. The inverse triangular is maintained to not bend the artificial limb joint until the user's forefoot land down again for each step.
