Embodiment 1
[0019] The present invention includes an opening training part 1 and an operating part used in conjunction with the opening training part 1; it is characterized in that: the shape of the opening training part 1 is a cone with a thick end and a thin end; the operating part is connected by an operating handle 3 and The connecting part 2 is rigidly fixed; the connection mode between the connecting part 2 and the opening training part 3 is to realize relative sliding connection in the axial direction.
[0020] The relative sliding connection is that the opening training part 1 is provided with an internal thread that matches the external thread of the connecting piece 2 . Adopting this linking method allows the patient to move the connecting piece 2 out of the opening training part 1 in the axial direction by rotating the operating handle 3 during use, which is convenient for the patient to hold the operating handle 3 for rehabilitation exercises. When not in use, the carrying vol...
Embodiment 2
[0023] Compared with the embodiment, the difference is: the relative sliding connection is an interference fit between the opening training part 1 and the connecting part 2 . Adopting this linking method can enable the patient to move the connecting piece 2 out of the opening training part 1 in the axial direction by pulling the operating handle 3 outward during use, so that the patient can easily hold the operating handle 3 for rehabilitation exercises. When not in use, the carrying volume of the training device can be reduced by pushing the operating handle 3 inward to move the connecting piece 2 axially from the opening training part 1 .
[0024] Since the connection part 2 and the opening training part 1 adopt an interference fit, a stronger air pressure will be generated in the inner space of the opening training part 1 during use, which makes it more difficult to pull out and push the connection part 2 . In order to solve this problem and better realize the effect of pul...
