Preferably, the exoskeleton slide three-sided rail slide structure.

The utility model has the advantages that:

1. the utility model discloses utilize the removal flexibility of lead screw slider (screw lead screw + ectoskeleton slider) for on adjusting the problem of different heights, according to patient's height promptly, adjust the upper and lower position of ectoskeleton slider on the lead screw, and then adjusted the position of the relative frame of connecting piece.

2. The utility model discloses utilize optical axis A direction, cooperation screw thread lead screw has strengthened lift platform operating stability, and through the cooperation of lead screw with the slider structure, can carry out nimble adjustment according to human height.

3. The utility model discloses the technique adopts the design of symmetry formula, has fully considered its atress condition, and structural design is reasonable pleasing to the eye.

4. The utility model discloses in the use, the screw lead screw atress is great, adopts the bulky design of connecting block A than connecting block B, and the area of contact of connecting block A and frame is bigger, increases its stability.

5. The utility model discloses the ectoskeleton slider adopts trilateral guide rail slider design for the firm laminating of holistic lift platform is on straight support, reinforcing stability.

6. The utility model discloses the connecting piece is connected with the ectoskeleton, and when the human walking, the connecting piece can reciprocate along with the human body through compression spring, makes it synchronous with human focus, avoids human focus to reciprocate the problem of bringing, is favorable to the patient to be recovered.

7. The utility model discloses the technique adopts slider, spring, screw lead screw part design, and more traditional rope draws formula design safety that stabilizes.
