One end of the traction rope 42 is fixedly connected to the support shaft 62, and a first pressure sensor 63 is installed on the support shaft 62. The first pressure sensor 63 is provided so that when one end of the traction rope 42 is wound around the support shaft 62 until a certain force is reached, the pressure sensor detects that its signal value changes, so that the traction rope 42 pulls the patient's finger through the first connecting belt 57 or the second connecting belt 58 and pulls it back and forth; A synchronous gear 64 is fixedly mounted on one end of the support shaft 62 located outside the support shell 61; A movable rotating member 7 is installed inside the protective shell 41 , and the movable rotating member 7 is used to drive multiple traction members 6 in sequence.

[0023] The movable rotating member 7 includes a rotating screw 71 rotatably connected to one side of the inner part of the protective shell 41, and a rotating motor 72 for driving the rotating screw 71 is installed on the outer side of the protective shell 41; A moving block 73 is threadedly sleeved on the outer side of the rotating screw rod 71, and the moving block 73 is slidably connected to the inside of the protective shell 41.

[0025] Specific implementation process: When the patient's fingers are subjected to hand-grip training, the fixing bracelet 1 is first fixed relatively to the patient's wrist through the fixing mechanism 2, and is fixed on both sides of the patient's wrist, so as to achieve stable clamping of the patient's wrist; Then, the five fixing members 5 are respectively put on the five fingers of the patient, that is, the five first arc plates 51 and the second arc plates 52 are respectively put on the patient's fingers, and stably fixed by the Velcro mother tape 53 and the Velcro child tape 54. At this time, the patient's fingers can move autonomously, and the traction rope 42 does not affect the movement of the patient's fingers; When the patient is performing hand-gripping training with his fingers facing the palm, in this embodiment, the second arc plate 52 is installed close to the patient's palm, and the rotating motor 72 at the protective shell 41 on the palm side is operated, so that the rotating screw 71 is rotated. When the rotating screw 71 rotates, a driving force is provided to the moving block 73. The moving block 73 drives the driving motor 74 to move along the inside of the protective shell 41 under the limiting action of the inner side of the protective shell 41 until the driving gear 75 approaches a synchronous gear 64. Then, under the action of the detection member 76, the driving gear 75 is stably meshed with the corresponding synchronous gear 64. At this time, the driving motor 74 is operated to further drive the synchronous gear 64 to rotate, and when the synchronous gear 64 At the same time as the rotation, the support shaft 62 is rotated, so as to realize the effect of winding up the traction rope 42 at the support shaft 62, and when the traction rope 42 is wound up, at this time, the traction rope 42 located on the back of the second arc-shaped plate 52 pulls the first connecting belt 57, and when the first connecting belt 57 is pulled, the pressing rod 564 is further driven to move through the pressing plate 565, so that the support plate 561 moves along the patient's fingers, and the multiple contacts 562 at the support plate 561 press the patient's fingers, and then, through the first arc-shaped plate 51, the patient's fingers are further pulled along the palm, and the driving motor 74 reciprocates, so as to realize the effect of reciprocating traction of the patient's fingers along the palm for hand-grip training; When the training of one finger is completed, the motor 72 is rotated to operate, so as to train the next finger, and the training is repeated in sequence; After the fingers are trained to bend along the palm, the rotary motor 72 inside the protective shell 41 near the back of the hand is operated, thereby pulling the second arc plate 52 through the second connecting belt 58, thereby further realizing the bending training of the patient's fingers along the back of the hand. Embodiment 2

[0026] See also Figure 14 to Figure 15 , Embodiment 2 is a further supplementary description of the telescopic member 22 of Embodiment 1, specifically, the fixed bracelet 1 is provided with a fixing port 11 at the positions corresponding to the two telescopic members 22, and two fixing blocks 221 are slidably connected at the fixing port 11, a bidirectional threaded screw 222 is threadedly connected at the fixing port 11, and the two fixing blocks 221 are threadedly sleeved on the outside of the bidirectional threaded screw 222, and a handle 223 for driving the bidirectional threaded screw 222 is installed on the fixed bracelet 1; Two first hinge supports are installed on one side of the two fixed blocks 221, and the first hinge supports are rotatably connected to the connecting rods 224, and the ends of the two connecting rods 224 away from the fixed blocks 221 are hinged to the second hinge supports through the pins, and the second hinge supports are installed on the clamping plate 21; Therefore, when fixing the fixed bracelet 1 on the patient's wrist, the fixed bracelet 1 is first put on the wrist by the patient's hand, and then the two handles 223 are rotated respectively, so that the bidirectional threaded screw 222 is rotated, and when the bidirectional threaded screw 222 rotates, it provides driving forces in opposite directions of the two fixed blocks 221, and due to the limiting effect of the fixing port 11, the two fixed blocks 221 are further moved toward each other, and when the fixed blocks 221 move toward each other, they drive the clamping plate 21 to move through the connecting support rod 224 until the two clamping plates 21 move toward each other, thereby clamping the patient's wrist, and further preventing the fixed bracelet 1 from moving.
