Positioning device for active/passive exercise training device for simulated weightless tail-suspended rat

The invention provides a tail-suspended rat positioning device, which comprises a tail suspending device, a rat fixing box, a trunk positioning device and an angle control device, wherein the rat fixing box is used for accommodating the head and the trunk part of a rat; the trunk positioning device is used for fixing the trunk of the rat; and the angle control device is used for controlling an angle between the rat fixing box and a base of the tail-suspended rat positioning device. The invention also provides an active/passive exercise training device for the tail-suspended rat, which comprises a rat hind limb exercise device, a track control device, an active exercise training device and a passive exercise training device, wherein the rat hind limb exercise device is used for performing active or passive exercise training on the hind limbs of the rat; the track control device is used for limiting the motion range of the hind limbs of the rat; the active exercise training device is used for performing active exercise training on the hind limbs of the rat; and the passive exercise training device is used for performing passive exercise training on the hind limbs of the rat. The devices can keep the tail suspending angle of the rat unchangeable, namely keep a simulated weightless state during exercise training, and can control the active/passive training for the rat to perform quantitative training.
