The invention discloses a wearable 
exoskeleton exercising and rehabilitating 
machine, which is designed according to the structure of a 
human skeleton, can exercise all parts of a 
human body and can perform rehabilitating traction on the 
human body. The wearable 
exoskeleton exercising and rehabilitating 
machine comprises two hand modules, two foot modules and a body module, wherein the two hand modules are in 
bilateral symmetry along the vertical 
central line of the body module; and the two foot modules are in 
bilateral symmetry along the vertical 
central line of the body module. In order to adapt to people with different heights, a hand extending component and a foot extending component are arranged and a screw rocker turnplate is arranged on the back to extend limbs. The whole wearable 
exoskeleton exercising and rehabilitating 
machine has 22 
degrees of freedom, namely 4 
degrees of freedom at the shoulders, 2 rotating 
degrees of freedom at the upper arm, 2 degrees of freedom at the elbows, 4 degrees of freedom at the hip, 2 rotating degrees of freedom at the upper legs, 2 degrees of freedom at the knees, 2 degrees of freedom at the ankles, 2 forward and backward degrees of freedom at the 
waist and 2 leftward and rightward degrees of freedom at the 
waist respectively. Through the 22 degrees of freedom, various motions of the limbs and the body can be realized, and through two different working 
modes, the exercising and rehabilitating functions can be realized.
