The using method comprises the following steps: when the device is used, the rotary rod 13 is rocked through the operation of the round rod 11, the rotary rod 13 drives the driving bevel gear 14 to rotate, the driving bevel gear 14 drives the driven bevel gear 17 to rotate, the driven bevel gear 17 drives the threaded rod 18 to rotate, the threaded rod 18 is matched with the threaded hole 23 at the bottom of the square supporting block 19, the lifting of the square supporting block 19 drives the supporting plate 20 is realized by utilizing the principle of threaded transmission, the height of the supporting plate 20 is further adjusted, feet are placed in the second transverse plate 33, the feet are inserted into the fixing belt 34, then the rotating speed of the servo motor 43 is adjusted through the control switch, the lower limb training intensity is adjusted to be suitable for the user, then the ball-shaped handle 52 is held by two hands to reciprocate back and forth, the sliding block 50 moves in the limiting groove 49, and the upper limb of the user is trained actively in the process of reciprocating back and forth sliding the sliding block, so that the purpose of rehabilitation training is achieved.
The installation method comprises the following steps:
firstly, symmetrically and fixedly mounting four self-locking universal wheels 6 on four corners of the bottom of a bottom plate 1 through screws, and locking the four self-locking universal wheels 6;
step two, according to the figures 5-8, assembling the lifting support unit 2, and after assembling, fixedly mounting the square shell 7 on the upper part of the bottom plate 1;
step three, the lower limb passive exercise unit 4 is assembled according to the method shown in fig. 9-11;
fourth, according to the figure 12, the upper limb active exercise unit 3 is assembled;
and fifthly, after the lifting support unit 2, the lower limb passive exercise unit 4 and the upper limb active exercise unit 3 are assembled, wiring installation control switches are arranged, namely the installation is finished.
None of the inventions are related to the same or are capable of being practiced in the prior art.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
