[0024] In this embodiment, the limb passive motion device body 1 mainly plays a role in leg rehabilitation exercises for patients, while the foot motion mechanism 2 and the leg motion mechanism 3 mainly play a role in leg activities for patients, and the fixed structure 5 mainly plays a role in fixing and positioning the limb passive motion device body 1, and the fixed positioning of the fixed structure 5 is mainly achieved through the clamping and positioning of the fixed component 505, the anti-slip effect is achieved through the rubber positioning plate 506, and the height can be adjusted through the telescopic rod 502, and the extension plate 503 serves as a connection to the special-shaped plate 504, and the receiving plate 501 serves as a connection between the fixed structure 5 and the connecting structure 4.

[0025] Example 2

[0026] like Figure 1-4As shown, a foot movement mechanism 2 is arranged on the top of the limb passive motion device body 1, and a leg movement mechanism 3 is arranged on the outer surfaces of both sides of the limb passive motion device body 1. The connecting structure 4 includes a fixed plate 401, and threaded tubes 403 are fixed on both sides of the outer surface of the fixed plate 401. The interior of the threaded tube 403 is connected with a connecting threaded rod 405 through a thread, and the outer surface of the connecting threaded rod 405 is connected with a threaded hole 404 through a thread, and a connecting plate 402 is arranged on the outer surface of one side of the threaded hole 404.

[0028] Working principle:

[0029] like Figure 1-4 As shown, in actual use, the limb passive motion device body 1 mainly plays a role in the patient's leg exercise, and the patient's legs are driven to move through the limb passive motion device body 1. The foot exercise mechanism 2 and the leg exercise mechanism 3 located on the top and surface of the limb passive motion device body 1 mainly play a role in the patient's leg movement, giving the patient a certain rehabilitation exercise effect, and the connection structure 4 located on the surface of the limb passive motion device body 1 mainly plays a role in connecting the fixed structure 5 part. The fixed structure 5 can be connected to the limb passive motion device body 1 through the connection structure 4. At the same time, the fixed structure 5 can be partially disassembled through the connection structure 4, and the fixed structure 5 mainly plays a role in fixing the limb passive motion device body 1 part and preventing the limb passive motion device body 1 from moving, etc.;

[0030] It should be noted here that the connecting structure 4 is mainly connected to the connecting plate 402 through the fixing plate 401, so that the fixing structure 5 is connected to the limb passive motion device body 1, and the fixing plate 401 and the connecting plate 402 have a disassembly effect. The connection and disassembly of the two need to be achieved through the threaded tube 403, the threaded hole 404 and the connecting threaded rod 405. The disassembly is performed by manually or using a tool to rotate the connecting threaded rod 405 so that the connecting threaded rod 405 is rotated and is located inside the threaded hole 404 and the threaded tube 403 through a threaded connection, and the connecting threaded rod 405 is gradually disengaged from the inside of the threaded tube 403, and the disassembly is completed by continuously rotating it to disengage from the inside of the threaded hole 404, while the installation can be performed in reverse. When the fixing structure 5 part is needed, When fixing the limb passive motion device body 1, the fixing structure 5 is mainly connected through the connecting structure 4, and the length part is adjusted through the telescopic rod 502 in the fixing structure 5. After adjusting to a suitable position, it is clamped and fixed by the fixing component 505 of the special-shaped plate 504. The rubber positioning plate 506 located at the fixing component 505 mainly plays a certain anti-slip effect, and the extension plate 503 mainly plays a role in connecting with the special-shaped plate 504, and the receiving plate 501 mainly plays a role in receiving components such as the telescopic rod 502 and the extension plate 503. The fixing component 505 and the rubber positioning plate 506 play a positioning role, and the fixing component 505 is mainly composed of bolts, screw holes and plates, and the bolts and screw holes are linked to push the plate to move to achieve a clamping, positioning and fixing effect;

[0031] Secondly, it should be noted that the positioning and fixing of the fixing structure 5 is mainly achieved by clamping and positioning the bed leg parts or by using other fixed components for clamping and positioning.
