[0033] See also Figure 1 , Figure 2 , Figure 5 , Figure 6 When in use, the motor 6 is started, and the output shaft of the motor 6 rotates to drive the rotating sleeve 7 to rotate. When the rotating sleeve 7 rotates, it can drive the traction rope 8 to wrap around the outside of the rotating sleeve 7, thereby driving the hand fixing plate 3 to rotate around the rotating point, so as to achieve the purpose of adjusting the angle of the hand fixing plate 3, and then drive the patient's palm to abduct.

[0034] Furthermore, a controller 9 is fixedly connected to the outside of the installation box 5 , and the controller 9 is signal-connected to the motor 6 .

[0035] See also Figure 1 The controller 9 can control the number of turns and the holding time of the rotating sleeve 7 driven by the motor 6, so that the patient's palm can be turned outward to a certain angle and kept in the abducted state for a period of time. The specific turning angle and time can be set according to the patient's condition, making the operation simpler and more adjustable.

[0036] Furthermore, a heightening plate 10 is fixedly connected to the bottom of the arm placement plate 4 , and the traction rope 8 is located inside the heightening plate 10 .

[0037] See also Figure 1 , Figure 2 The heightening plate 10 can raise the patient's arm to a certain height, so that the patient's arm is in a more comfortable state, and plays a role in protecting the traction rope 8 from being affected during movement.

When in use, multiple straps 11 are wrapped around the patient's arm one by one, and the other end of the strap 11 is passed through the corresponding loop 12, and the end of the strap 11 is connected to the loop 12 by Velcro 13, thereby fixing the patient's arm.

[0040] Furthermore, the connecting member includes a rotating shaft rotatably connected to the end of the hand rest plate 1, and a connecting plate 14 is fixedly connected to the end of the rotating shaft away from the hand rest plate 1. The connecting plate 14 is located at the end of the hand rest plate 1 away from the arm rest plate 4, and a through hole 15 is constructed at a position corresponding to the connecting plate 14 on the hand fixing plate 3, and the shape of the connecting plate 14 is adapted to the shape of the through hole 15.

[0041] See also Figure 7 , Figure 8 When in use, turn the hand placement plate 1 over so that the patient's palm faces upward, and the patient's hand is between the hand placement plate 1 and the hand fixing plate 3. Then, pass the connecting plate 14 on the hand placement plate 1 through the through hole 15, and then rotate the connecting plate 14 so that the connecting plate 14 and the through hole 15 are in a vertical state, thereby connecting the hand placement plate 1 and the hand fixing plate 3 together.

[0042] Furthermore, six finger fixing sleeves 2 are provided.

[0043] See also Figure 1 The two outer fingers of the finger fixing sleeve 2 correspond to the thumbs of the left and right hands respectively, so it is convenient to put the fingers of the left hand or the right hand into the finger fixing sleeve 2 one by one.

[0044] Furthermore, a protective pad 16 is fixedly connected to the inside of the hand placement board 1 at a position corresponding to the elbow.

[0045] See also Figure 1 The protective pad 16 is made of a relatively soft material. During the pulling process, the joint at the elbow will rotate, and the protective pad 16 plays a role in protecting the joint at the elbow.

[0046] Furthermore, a limiting block 17 is fixedly connected to one end of the arm placement plate 4 close to the hand fixing plate 3 , and the limiting block 17 is used to limit the rotation angle of the hand fixing plate 3 .

[0047] See also Figure 2 , Figure 3 The limiting block 17 is used to limit the rotation angle of the hand fixing plate 3 to prevent the hand fixing plate 3 from rotating too much and causing injury to the patient.

[0048] Working principle: When the hand exercise device is used, the arm placement board 4 and the height-increasing board 10 are first placed beside the bed, and then the patient is helped to place his hand on the hand placement board 1, and each finger of the left or right hand is inserted into the finger fixing sleeve 2 and fixed one by one, and the patient is helped to turn the hand placement board 1 over so that the palm of the patient faces upward, and the connecting plate 14 on the hand placement board 1 passes through the through hole 15, and then the connecting plate 14 is rotated so that the connecting plate 14 and the through hole 15 are in a vertical state, thereby connecting the hand placement board 1 and the hand fixing board 3 together, so that the hand is located between the hand placement board 1 and the hand fixing board 3, and the palm faces upward.

[0049] The patient's arm is then placed on the arm placement board 4, multiple straps 11 are wrapped around the patient's arm one by one, and the other end of the strap 11 is passed through the corresponding loop 12, and the end of the strap 11 is connected to the loop 12 through the Velcro 13 to fix the patient's arm on the arm placement board 4, and then the controller 9 is turned on to set the number of revolutions of the rotating sleeve 7 driven by the motor 6 and the duration of the motor 6 after rotation, and then the motor 6 is started, and the output shaft of the motor 6 rotates to drive the rotating sleeve 7 to rotate. When the rotating sleeve 7 rotates, it can drive the traction rope 8 to wrap around the outside of the rotating sleeve 7, thereby driving the hand fixing plate 3 to rotate around the rotation point, so as to achieve the purpose of adjusting the angle of the hand fixing plate 3, and then drive the patient's arm and palm to be in an abducted state for a period of time. After the training is completed, the motor 6 is reversed to drive the traction rope 8 to extend, so that the hand fixing plate 3 is restored to its initial state, and then the hand is removed from the hand placement board 1.
