[0043] Further, the engaging transmission assembly comprises engaging transmission frames symmetrically mounted on the inclined sections where the two transmission rails 411 are located, each engaging transmission frame comprises a through slot 420 opened on the inclined section, a sliding block 421 is arranged in the through slot 420, and a transmission shaft 422 is rotatably arranged with the sliding block 421, one end of the transmission shaft 422 is fixed with an output end of a driving motor 423 arranged on the inner side of the sliding block 421, and the other end of the transmission shaft 422 is outwardly fixed with a gear 4241; further comprising a rack 4242 fixed on the outer side of the inclined section where the transmission rail 411 is located, and the rack 4242 is in meshing with the gear 4241; the outer end of the transmission shaft 422 is further rotatably arranged with a push-pull rod 418, and one end of the push-pull rod 418 away from the transmission shaft 422 is rotatably arranged with the first connecting shaft 415.

When the knee joint CPM machine 428 needs to be assembled on the upper surface of the second plate, first, the connecting block 4281 on the side of the knee joint CPM machine 428 is aligned with the assembly block 426, and the first through hole 4282 is aligned with the first screw hole provided on the assembly block 426. Then, the first bolt 427 is inserted through the first through hole 4282 and is connected with the corresponding first screw hole, so that the assembly of the knee joint CPM machine 428 and the first hip plate 4142 is completed.

[0048] Further, the first hip plate 4142 is also provided with a circular hole 429, as shown. Figure 2 As shown, when the device is in a sleep state, the circular hole 429 is provided for the patient who is paralyzed in bed to facilitate the toilet.

[0049] Further, the side of the first hip plate 4142 away from the leg plate 4132 is also fixed with a second hip plate 430, and a plurality of air holes 431 are provided on the second hip plate 430; and a groove is provided at the bottom of the front end of the third plate, which is used for the inlaying of the second hip plate 430.

[0050] As shown, Figure 3 The second hip plate 430 of the application is arranged on the rear side of the first hip plate 4142 and can be inlaid in the auxiliary standing frame.
