[0036] When in use, first twist the knob 303 to rotate or reverse, so that the knob 303 drives the screw rod 302 to rotate or reverse, thereby driving the connecting plate 301, the sliding plate 2, the rotating plate 4 and the first arc-shaped storage seat 6 to move left or right, so as to adjust the distance between the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8, so that the distance between the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8 is adapted to the patient's arm length. After the adjustment is completed, the telescopic rod of the first electric push rod 14 is controlled to extend, so that the first electric push rod 14 The telescopic rod of the rod 14 squeezes the movable frame 13 to rotate until the movable frame 13 is in a vertical state, and then the second servo motor 903 drives the rotating rod 901 to rotate through the pulley assembly 904, so that the rotating rod 901 drives the arc-shaped limiting plate 902 to rotate and unfold, and then the patient's upper arm is placed on the first arc-shaped placement seat 6, and the patient's forearm is placed on the second arc-shaped placement seat 8, and the patient's palm is placed on the support plate 12, and then the second servo motor 903 drives the rotating rod 9 through the pulley assembly 904. 01 is reversed and reset, so that the rotating rod 901 drives the arc-shaped limiting plate 902 to reverse and reset, so that the arc-shaped limiting plate 902 limits the patient's limbs on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8, and then the first servo motor 502 drives the second gear 504 to intermittently rotate forward and reverse, thereby driving the first gear 503, the rotating plate 4 and the first arc-shaped storage seat 6 to intermittently rotate forward and reverse, so that the first arc-shaped storage seat 6 drives the patient's forearm to reciprocate, thereby completing the flexion and The patient's forearm is stretched forward to perform rehabilitation training. During this period, when the patient's forearm is compressed or stretched, it will apply pressure to drive the first arc-shaped storage seat 6 to slide on the rotating plate 4. The spring 7 is adaptively deformed to automatically adjust the position of the first arc-shaped storage seat 6, so that the position of the first arc-shaped storage seat 6 is more suitable for the patient's arm in motion, and it is prevented from being too tight and causing pain to the patient. When the patient's forearm releases the pressure on the first arc-shaped storage seat 6, the spring 7 will automatically reset and drive the first arc-shaped storage seat 6 to slide and reset on the rotating plate 4;After the patient's elbow joint has been flexed and extended for a period of time, the first servo motor 502 drives the second gear 504 to stop rotating, so that the patient's elbow joint stops flexing and extending, and the patient's palm stays on the support plate 12, and then the telescopic rod of the first electric push rod 14 is controlled to shorten, so that the telescopic rod of the first electric push rod 14 pulls the movable frame 13 to reverse and reset until the movable frame 13 is horizontal, and then the patient holds the movable frame 13, and then the reduction motor 11 drives the support plate 12 and the movable frame 13 to perform intermittent forward and reverse rotation, thereby driving the patient's hand to perform intermittent forward and reverse rotation, so as to more comprehensively exercise the muscle groups around the elbow joint, promote blood circulation, reduce muscle fatigue, and thus accelerate the rehabilitation process. After the patient's hand has been intermittently rotated forward and reverse for a period of time, the reduction motor 11 drives the support plate 12 and the movable frame 13 to stop rotating, so that the patient's hand stops intermittent forward and reverse rotation, and then the telescopic rod of the first electric push rod 14 is controlled to extend again. The telescopic rod of the rod 14 squeezes the movable frame 13 to rotate until the movable frame 13 is in a vertical state, and then repeats the above operation, so that the patient can choose to use or alternately use the two training methods of elbow flexion and extension and intermittent rotation of the hand, thereby increasing the flexibility and diversity of the training method to meet the personalized needs of different patients. In addition, through appropriate intermittent adjustment and diversified training modes, it is possible to prevent the patient's muscle fatigue or even damage, which is beneficial to the patient's long-term rehabilitation. When the patient completes all rehabilitation training, the second servo motor 903 is used to drive the rotating rod 901 to rotate through the pulley assembly 904, so that the rotating rod 901 drives the arc-shaped limiting plate 902 to rotate and unfold, and then the patient's hand is taken out from the first arc-shaped storage seat 6, the second arc-shaped storage seat 8 and the supporting plate 12, and then the second servo motor 903 is used to drive the rotating rod 901 through the pulley assembly 904 to reverse and reset, so that the rotating rod 901 drives the arc-shaped limiting plate 902 to reverse and reset. ;

[0037] See also Figure 9-11 As shown, it also includes a clamping mechanism, which includes an air pump 15, an air bag 16, an air pipe 17 and an air valve 18; the air pump 15 is installed on the support seat 1; the air bags 16 are installed on the first arc-shaped storage seat 6, the second arc-shaped storage seat 8 and the arc-shaped limiting plate 902; bumps 1601 are arranged at intervals on the air bags 16, and the bumps 1601 are used to massage the patient's limbs; the air pipe 17 is installed on the rear side of the front sliding plate 2, and the air outlet of the air pump 15 is connected with the air bag 16 through the air pipe 17; the air valve 18 is arranged on the air pipe 17, and the air valve 18 is used to discharge the gas in the air bag 16.

[0038] See also Fig. 9 and Fig.11As shown, it also includes an automatic control mechanism, which includes a pressure gauge 19 and a controller 20; the pressure gauge 19 and the controller 20 are installed on the front side of the front sliding plate 2, and the controller 20 is located on the lower right side of the pressure gauge 19. The pressure gauge 19 is connected to the air pipe 17, and the pressure gauge 19, the air valve 18 and the air pump 15 are all electrically connected to the controller 20, and the controller 20 is used to control the start and stop of the air pump 15.

[0039] By setting a close-fitting mechanism and an automatic control mechanism, when the patient's arm is placed on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8, the patient's arm will contact the airbag 16 and the protrusion 1601. After that, when the patient's limbs on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8 are limited by the arc-shaped limiting plate 902, the air pump 15 is started by the controller 20, so that the air pump 15 draws air into the airbag 16 through the trachea 17, so that the airbag 16 expands, and then the airbag 16 and the protrusion 1601 are close to the patient's arm, so as to adjust the position of the patient's arm to different sizes. The patient is fixed, and when the airbag 16 and the convex block 1601 are in close contact with the patient's arm, as the airbag 16 continues to inflate, the air pressure therein will gradually increase. When the barometer 19 detects that the air pressure in the airbag 16 and the trachea 17 is greater than the preset value, the barometer 19 will control the air pump 15 to be closed through the controller 20, so that the air pump 15 stops pumping gas into the airbag 16, thereby stopping the airbag 16 from expanding to prevent the excessive expansion of the airbag 16 from causing discomfort to the patient's arm; thereafter, when the patient's arm is being trained, the air valve 18 and the air pump 15 can be controlled by the controller 20 The air pump 15 is intermittently started and stopped. When the air valve 18 is opened, the gas in the airbag 16 is discharged through the air valve 18, causing the airbag 16 to shrink, so that the airbag 16 retracts the protrusion 1601 by shrinking, so that the protrusion 1601 slightly loosens the patient's limb. When the air valve 18 stops, the gas in the airbag 16 stops being discharged. When the air pump 15 is opened, the air pump 15 draws gas into the airbag 16 to expand the airbag 16, so that the airbag 16 squeezes the protrusion 1601 by expanding, so that the protrusion 1601 slightly presses the patient's limb (to a certain extent). Massage effect can be achieved), when the air pump 15 is turned off, the air pump 15 will stop pumping air, and this reciprocating process can make the airbag 16 intermittently expand and contract, so that the protrusion 1601 intermittently presses the patient's limbs, thereby massaging the patient's limbs and preventing the formation of venous thrombosis in the patient's limbs; when the patient completes all the rehabilitation training, the controller 20 controls the air valve 18 to open, so that the gas in the airbag 16 and the trachea 17 is discharged through the air valve 18, thereby causing the airbag 16 to shrink and reset, and finally the controller 20 controls the air valve 18 to close.

[0040] See also Figure 7As shown, it also includes an electromagnet 21; an electromagnet 21 is installed on the rear side of the arc-shaped limiting plate 902 on the left, and an electromagnet 21 is also installed on the rear side of the bottom of the arc-shaped limiting plate 902 on the right. After the electromagnet 21 is energized, it is used to adsorb the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8.

[0041] By setting the electromagnet 21, when the arc-shaped limiting plate 902 limits the patient's limbs on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8, the electromagnet 21 can be energized to make the electromagnet 21 adsorbed on the first arc-shaped storage seat 6 or the second arc-shaped storage seat 8, so as to enhance the stability of the arc-shaped limiting plate 902; when it is necessary to release the patient's limbs on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8 by the arc-shaped limiting plate 902, the electromagnet 21 is firstly de-energized to make the electromagnet 21 release the first arc-shaped storage seat 6 or the second arc-shaped storage seat 8, and then the arc-shaped limiting plate 902 can release the patient's limbs on the first arc-shaped storage seat 6 and the second arc-shaped storage seat 8.

[0042] See also Fig. 9 , Fig.10 and Fig.12 As shown, it also includes a lifting mechanism, which includes a connecting frame 22, a cloth winding shaft 23, a connecting belt 24, a torsion spring 25 and a pull rod 26; the support seat 1 is symmetrically provided with connecting frames 22, and the number of the connecting frames 22 is four; the cloth winding shaft 23 is rotatably installed in the connecting frame 22; a connecting belt 24 is wound around the cloth winding shaft 23, and one end of the connecting belt 24 is fixed to the cloth winding shaft 23; a torsion spring 25 is connected between the cloth winding shaft 23 and the left wall inside the connecting frame 22; the other end of the connecting belt 24 extends out of the connecting frame 22, and a pull rod 26 is connected between the other ends of the two connecting belts 24 on the front side, and a pull rod 26 is also connected between the other ends of the two connecting belts 24 on the rear side.

[0043] By setting up a lifting mechanism, when the user needs to carry the training auxiliary device for movement, the two pull rods 26 can be pulled upward and gradually approached to make the two pull rods 26 contact. During this period, the pull rods 26 will drive the connecting belt 24 to unfold when moving upward, so that the connecting belt 24 drives the cloth winding shaft 23 to rotate, and the torsion spring 25 is deformed. Then the user can lift the two pull rods 26 to drive the training auxiliary device to move. In this way, it is convenient for the user to carry the training auxiliary device for movement; when the training auxiliary device is placed in the specified position, the two pull rods 26 are released again. At this time, the torsion spring 25 returns to its original state, and the torsion spring 25 drives the cloth winding shaft 23 to reverse and reset, so that the cloth winding shaft 23 retracts the connecting belt 24, so that the connecting belt 24 drives the pull rod 26 to move downward and reset and gradually separate.

[0044] See also Fig.13As shown, it also includes a shoulder joint training mechanism, which includes a base 27, a second electric push rod 28 and a support block 29; the base 27 is rotatably arranged on the right side of the bottom of the support seat 1; the second electric push rod 28 is rotatably arranged on the left side of the top of the base 27, and the telescopic rod of the second electric push rod 28 is rotatably connected to the middle of the bottom of the support seat 1; a support block 29 is arranged on the left side of the top of the base 27, and the top of the support block 29 is in contact with the left side of the bottom of the support seat 1, and the support block 29 is used to support the support seat 1.

[0045] By setting up a shoulder joint training mechanism, when the patient's arm is being trained, the telescopic rod of the second electric push rod 28 can be controlled to intermittently extend and shorten. When the telescopic rod of the second electric push rod 28 is extended, the telescopic rod of the second electric push rod 28 will squeeze the support seat 1 to rotate, thereby driving the patient's arm to be lifted; when the telescopic rod of the second electric push rod 28 is shortened, the telescopic rod of the second electric push rod 28 will pull the support seat 1 to reverse and reset, thereby driving the patient's arm to be lowered. In this way, the patient's shoulder joint can be trained by reciprocatingly driving the patient's arm to be lifted and lowered.
