[0038] The specific implementation process is as follows:
[0039] When using this device, first adjust the height of the seat 2, then adjust the distance between the seat 2 and the lower limb training assembly, place both legs on the lower limb training assemblies on both sides, with the calves located on the lower support plate 15, the thighs located on the upper support plate 14, the popliteal fossa located on the mounting tube 17, and the soles of the feet placed on the sole support plate 34. Use the fixing belt 18 to fix the thighs, calves and soles of the feet, fasten the safety belt 3, and hold the annular pull ring 30 with both hands; start the first motor 9 and the second motor 20, the first motor 9 drives the rotating shaft 8 to rotate forward / reverse, the rotating shaft 8 drives the two active bevel gears 10 to rotate forward / reverse, the active bevel gear 10 drives the driven bevel gear 12 meshing with it to rotate forward / reverse, the driven bevel gear 12 drives the screw rod 11 to rotate forward / reverse, the screw rod 11 drives the wire seat 13 to slide left / right along its axis, and the wire seat 13 drives the lower support plate 15 to move left / right along the axis of the screw rod 11 , rotates upward / downward along the wire seat 13, and drives the upper support plate 14 to rotate upward / downward, thereby realizing reciprocating knee flexion training; when the lower support plate 15 moves to the left along the axis of the screw rod 11, the second tension spring 35 is stretched, and the second tension spring 35 applies a reaction force to the sole support plate 34, causing it to rotate downward. When the lower support plate 15 moves to the right along the axis of the screw rod 11, the tensioning force of the second tension spring 35 gradually decreases, and the sole support plate 34 gradually recovers under the action of the reset torsion spring; at the same time, the rotating shaft 8 drives the winding drum 26 to rotate forward / reverse. When the winding drum 26 rotates forward, it rewinds the tension rope 27, and the tension rope 27 moves upward and stretches the first tension spring 32 upward, thereby driving the user's arm to stretch upward; when the winding drum 26 reverses, it releases the tension rope 27, and the tension rope 27 moves downward under the action of the rebound force of the first tension spring 32, thereby driving the user's arm to contract downward.

In the process of moving left / right along the length direction of the mounting box 7, the lower support plate 15 also drives the upper support plate 14 to rotate up / down, so as to realize the folding or stretching of the upper support plate 14 and the lower support plate 15 with each other to realize reciprocating knee flexion training; the upper limb training component includes a reel 26, a tension rope 27, and a pulley 29. While the rotating shaft 8 drives the lower support plate 15 to move, it also drives the reel 26 to rotate forward and reverse, so that the reel 26 releases / retracts the tension rope 27, thereby driving the user's arm to stretch / contract, so as to exercise the patient's upper limb muscles and shoulder and back muscles and avoid muscle atrophy.
[0041] The transmission assembly includes an active bevel gear 10, a driven bevel gear 12, a screw rod 11, and a screw seat 13. The motor drives the rotating shaft 8 to rotate forward / reverse, driving the active bevel gear 10 to rotate forward / reverse, driving the screw seat 13 to slide left / right along the axis of the screw rod 11. The screw seat 13 drives the lower support plate 15 to move left / right along the axis of the screw rod 11, while rotating up / down with the screw seat 13 as the center, and drives the upper support plate 14 to rotate up / down along the connection point with the mounting seat, so as to realize the upper support plate 14 and the lower support plate 15 to fold or stretch each other, thereby performing reciprocating knee flexion training.

[0042] The massage component includes several groups of squeeze airbags 21 arranged in pairs. The squeeze airbags 21 are connected to the electric air pump 22 through the trachea. The two cams 25 alternately squeeze the inflation press switch 23 and the deflation press switch 24 to inflate and deflate the squeeze airbags 21, so as to achieve intermittent squeezing massage on both sides of the user's thighs and calves. The airbags have good flexibility to avoid secondary injury to the patient; and the cams 25 are connected to the screw rod 11, that is, the frequency of inflation and deflation of the squeeze airbags 21 is related to the rotation speed of the screw rod 11, and the massage intensity can adapt to the training intensity, further increasing the training effect. For example, the faster the screw rod 11 rotates, the higher the frequency and intensity of the reciprocating knee flexion training, and the faster the frequency of the squeezing massage of the squeeze airbags 21. The massage assembly also includes a plurality of massage rollers 19. The upper support plate 14 and the lower support plate 15 are provided with a plurality of square holes. The massage rollers 19 are rotatably connected to the square holes through the rotating shaft 8. The rotating shaft 8 is connected to the second motor 20. The second motor 20 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the massage rollers 19 to rotate to achieve muscle massage on the user's calf and back thigh, thereby activating the muscles.
[0043] The upper support plate 14 is connected to a mounting shaft 16 at its end away from the mounting box 7, and the lower support plate 15 is connected to a mounting tube 17 at its end near the upper support plate 14.

The mounting tube 17 is also provided with a soft support pad to reduce localized pressure on the user's popliteal fossa and increase comfort. The annular pull ring 30 facilitates user use and prevents slippage. The limit plate 31 cooperates with the annular pull ring 30 to prevent the pull rope 27 from disengaging from the pulley 29, increasing ease of use. The connecting rod 28 is a telescopic rod that can adjust the height of the pulley 29 to adjust the degree of arm extension and thus the intensity of the training. The bottom end of the seat 2 is connected to a telescopic cylinder 4, the free end of which is connected to the base 1 to facilitate adjustment of the seat 2's height. The telescopic cylinder 4 is slidably connected to the base 1 via a strip groove and a slider. The base 1 is provided with a fixing 6 to limit the sliding of the telescopic cylinder 4, which can adjust the distance between the seat 2 and the lower limb training assembly and the upper limb training assembly to meet different personalized needs. When the lower support plate 15 slides leftward along the axial direction of the screw rod 11, the second tension spring 35 extends and applies a tension to the sole support plate 34, so that the sole support plate 34 overcomes the return torsion spring and rotates toward the second tension spring 35 to exercise the user's ankle.
