[0056] In the embodiment, the relative rotation range of the big arm component 1 and the small arm component 4 is 0° to 180°, so that shrinkage placement can be achieved. Two fixed holes 122 used for hanging the mechanical arm are formed in the upper portion of the big arm back plate 12. The big arm shell 11 and the small arm shell 44 are both hollow shells. The inner supporting rod 22 can be locked unidirectionally through the ratchet wheel 252, a square hole 221 connected with the ratchet wheel 252 is formed in one end of the inner supporting rod 22, and a pressing shrinkage structure 222 is arranged at the other end of the inner supporting rod 22. The pressing shrinkage structure 222 consists of a steel ball 2221 and a pressing spring 2222. The outer supporting rod 23 is in a hollow pipe shape, six pairs of fixed through holes 232 which are evenly distributed are symmetrically formed in the side wall of the outer supporting rod 23, and an anti-skid sheath 231 is arranged at the tail end of the outer supporting rod 23. Grooves 211 and 212 for accommodating the inner supporting rod 22 and the outer supporting rod 23 and mounting the reversing component 25 are formed in the supporting base 21. The first big arm support 13, the second big arm support 14, the first small arm support 41, the second small arm support 42, the hand binding band 611 and the finger binding band 621 are all made of hook and loop fasteners. The adjusting knob 333 penetrates through the through holes 3361 in the wire plate 334 and the wire plate cover plate 335 to form mechanical limit. The six through holes 3361 in the wire plate 334 and the wire plate cover plate 335 form six gears. The surface of the elbow motor shell 31 is provided with character identifiers for displaying gears where the adjusting knob 333 is located. The number of the vibration components 62 corresponding to the finger joints is fourteen.

[0057] When the mechanical arm is used, the first big arm support 13 and the second big arm support 14 are fixed to a big arm of a human body, and the first small arm support 41 and the second small arm support 42 are fixed to a small arm of the human body. The sealing piece 24 is taken down. The button 255 is pressed down. The inner supporting rod 22 and the outer supporting rod 23 are screwed out of the groove 211 in the supporting base 21. The outer supporting rod 23 is pulled relative to the inner supporting rod 22, so that the steel ball 2221 extrudes the pressing spring 2222. When the steel ball 2221 reaches the position of the fixed through hole 232 in the outer supporting rod 23, the steel ball 2221 resets, the inner supporting rod 22 and the outer supporting rod 23 are fixed together through the pressing shrinkage structure 222, and the screw-out angle and the pulling distance are adjusted, so that the inner supporting rod 22 and the outer supporting rod 23 can support the big arm of the human body. The button 255 is loosened, the inner supporting rod 22 is locked, and the antiskid sheath 231 prevents the mechanical arm from sliding. The knob cap 331 is pulled, the adjusting knob 333 is pulled to be separated from the through hole 3361 in the wire plate 334, and the adjusting knob 333 is slid along the arc-shaped groove 121 in the big arm back plate 12. For example, when the adjusting knob 333 is adjusted to the third gear displayed on the surface of the elbow motor shell 31, the knob cap 331 is loosened. Under the action of the knob spring 332, the adjusting knob 333 is inserted into the through hole 3361, corresponding to the third gear, in the wire plate 334 again, and mechanical limit is formed. When the bulge 431 on the small arm back plate 43 makes contact with the adjustment knob 333, the downward movement of the small arm component 4 is limited. The adjusting knob 333 makes contact with the wire plate 334, and the resistance R of the elbow joint motor 32 is changed. The elbow joint motor 32 is controlled to rotate in the range of the third gear in a reciprocating mode through a preset control program. The upper limited block 337 limits the small arm component 4 to move upwards. In addition, soft limit can be performed through the control program. The hand component 6 is fixed to the second wrist supporting plate 56. The hand binding band 611 is fixed to the palm of the human body. The finger binding band 621 is fixed to the fingers of the human body respectively. The first wrist motor 51 rotates to drive the hand component 6, the second wrist motor 52 and the second wrist supporting plate 56 to rotate by multiple motions, so that inward rotation and outward rotation of the wrist are achieved. The second wrist motor 52 rotates to drive the hand component 6 to rotate, so that inversion and eversion of the wrist are realized. The vibration components 62 correspond to fourteen joints of fingers of the human body. Through vibration of the microvibration unit 622, the finger joints of the patient can be massaged, and the purpose of activating finger nerves and muscles is achieved.
