[0028] In this specific embodiment, a reinforcing rod 15 is fixedly connected between the vertical rod 7 and the horizontal rod 8, so that the structure of the horizontal rod 8 is more stable.

[0029] In this specific embodiment, a battery box 16 is provided on the front side of the base 1 , and the battery is disposed in the battery box 16 .

[0030] In this specific embodiment, a mounting bracket 17 is fixedly provided on the base 1 , and a flat plate 18 is provided on the upper end of the mounting bracket 17 . The flat plate 18 is electrically connected to the battery.

[0031] In this specific embodiment, the mounting bracket 17 is an adjustable telescopic rod.

[0032] In this specific embodiment, the guardrail includes symmetrically arranged adjustable support rods 19 and a side rail 12 fixedly connected to the upper end between the two adjustable support rods 19. The adjustable support rods 19 are adjustable telescopic rods.

[0033] In this specific embodiment, the limiting device includes a lower limb rear limiting plate 20, a lower limb front limiting plate 21 and a plurality of straps 22 with Velcro, which are fixed to the foot pedal 3.

[0035] Working principle:

[0036] Lower limb training process:

[0037] The patient sits on chair 24 or stands, and steps on foot pedals 3 with both feet secured by straps 22. This pedaling action rotates the crank and shaft, which, after being accelerated by a gear transmission, drives a generator to generate electricity, which is then stored in a battery. A stopper prevents the foot from shifting.

[0038] Upper limb training process:

[0039] The patient holds the pull rod 4 to stretch, and the wire rope 11 pulls the counterweight up. The user adjusts the training intensity by turning the threaded rod 13 via the adjustment wheel 14 to increase the friction between the counterweight and the threaded rod 13. The fixed pulley assembly reduces wear on the wire rope, and the reinforcing rod 15 ensures the load-bearing stability of the cross bar 8. When the threaded rod 13 is tightened to a certain level of friction between the counterweight and the threaded rod 13, the user can stand up and continue exercising by holding the pull rod 4 with their hands.

[0040] In this technical solution, the battery can power the tablet 18 for displaying training data or entertainment functions; the height of the tablet 18 is adjusted by the mounting bracket 17 to adapt to sitting or standing use.

[0041] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0042] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0043] In the description of the embodiments of the present invention, "a plurality of" means at least two.

[0044] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0045] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
