The right end of the central shaft 21 is sleeved with the second bevel gear 26, the right bottom end of the bottom frame 23 is rotatably provided with the first bevel gear 25, the first bevel gear 25 is meshingly connected with the second bevel gear 26, the central shaft of the first bevel gear 25 penetrates below the bottom frame 23 and is sleeved with the adjusting knob 24, the top end of the movable sleeve frame 20 is fixedly connected with a first tension spring 16, the other end of the first tension spring 16 penetrates into the inner part of the leg plate 5 and is connected with the top end of the straight rod 7, the inner part of the leg plate 5 and located at the right side of the straight rod 7 is provided with a limiting post 34, which limits the counterclockwise deflection angle of the straight rod 7.

[0030] In this embodiment, the surface of the straight rod 7 and located around the connecting shaft 30 is provided with a side groove 27, the inner part of the side groove 27 and located at the surface of the connecting shaft 30 is provided with a clamping groove 28, the inner wall of the side groove 27 is fixedly connected with a fixed stand column 29 and a traction block 33, the surface of the fixed stand column 29 is movably sleeved with a pressing plate 31, and the pressing plate 31 is clamped with the connecting shaft 30 through the clamping groove 28 (as Figure 4When the pressing plate 31 is firmly attached to the engaging groove 28, the engaging groove 28 is locked, and the straight rod 7 is difficult to rotate around the connecting shaft 30. The traction block 33 is connected with a second tension spring 32, the other end of the second tension spring 32 is fixedly connected with the pressing plate 31, the other end of the traction line 11 is connected with the pressing rod 10, the bottom end of the straight rod 7 is swingably connected with the swing frame 9, the other end of the swing frame 9 is connected with the pressing rod 10.

[0031] In the embodiment, the first shaft 12 and the second shaft 14 are fixedly connected with the inside left and right sides of the bottom shell 4 respectively, the surface of the first shaft 12 is rotatably sleeved with the swing block 35, the swing block 35 is in the shape of 'P' (as shown in Figure 7 The head of the swing block 35 is wound with the belt 15, and the tail of the swing block 35 is connected with the third tension spring 38. The inside surface of the side baffle 13 is connected with the third tension spring 38, the other end of the third tension spring 38 is connected with the connecting bolt 39, the threaded end of the connecting bolt 39 penetrates through the other side of the swing block 35 and is sleeved with the threaded knob 36, the surface of the swing block 35 is wound with the belt 15, and the other end of the belt 15 is fixedly connected with the arc rod 6 after penetrating through the side baffle 13 and the second shaft 14.

[0032] The working principle of the device is that after the postoperative rehabilitation patient sits above the device, only needs to put two feet on the two foot pedals 8 respectively. At this time, the long end of the swing block 35 is pulled by the third tension spring 38 (as shown in Figure 5 、 7 The belt 15 wound on the swing block 35 will pull the arc rod 6 to swing outward, at this time, the leg plate 5 attached to the knee will push the patient to expand the thigh, and the patient only needs to tighten the leg plate 5 to realize the rehabilitation training of the thigh. When the tension of the thigh needs to be adjusted, only needs to rotate the threaded knob 36 (as shown in Figure 7 The pulling force of the third tension spring 38 on the swing block 35 can be increased or decreased.

[0033] When the patient performs the calf lifting training, the top end of the straight rod 7 is pulled by the first tension spring 16 (as shown in Figure 5 The straight rod 7 will be in the initial state of lifting. After the patient's calf is placed above the foot pedal 8, only needs to repeatedly press the foot pedal 8 to realize the rehabilitation training of the calf. When the tension of the first tension spring 16 needs to be adjusted, only needs to rotate the adjusting knob 24 (as shown in Figure 3As shown, the rotation of the adjusting knob 24 will drive the rotation of the screw gear 22 through the first and second bevel gears 25 and 26, so that the movable sleeve frame 20 can move left and right on the arc lever 6, and the tension of the first tension spring 16 can be adjusted.

[0034] When the patient's foot is not above the foot pedal 8, the pedal 10 is not pressed, and the traction line 11 is not pulled (as shown in Figure 4 As shown, the pressing plate 31 will be clamped in the clamping groove 28 under the action of the second tension spring 32, so that the angle of the straight lever 7 is fixed, and the foot pedal 8 will not be raised high when not in use, so as to facilitate the subsequent use of the patient.

[0035] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by ordinary skilled in the art within the scope of the present application also belong to the protection scope of the present application.
