The spur plate 1002 meshes with the gear 1001, so that the gear 1001 rotates, and the gear 1001 drives the rotating shaft 1006 to rotate, thereby rotating the rear arm support 704, so that the patient's arm can be flipped for rehabilitation training.
[0027] In order to adapt to different patients' arms. Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7The telescopic component 11 includes a slide rail 1101 and a slide plate 1102 slidably connected to the slide rail 1101.

Example 2:
[0028] Based on the first embodiment, this embodiment discloses an arm rehabilitation training device for medical care. Figure 6 、 Figure 7 and Figure 8 It mainly includes a T-shaped plate 1004 fixedly connected to the rotating frame 703, and a T-shaped slot 1005 adapted to the T-shaped plate 1004 is opened on the straight tooth plate 1002; through the matching design of the T-shaped plate 1004 and the T-shaped slot 1005, the straight tooth plate 1002 can be limited during the movement process, so that it can better engage with the gear 1001. Example 3:
[0029] Based on the first embodiment, this embodiment discloses an arm rehabilitation training device for medical care. Figure 4 and Figure 5 The limiting assembly 12 mainly includes an L-shaped plate 1201, a plug-in shaft 1202, a retaining ring 1203 and a spring 1204. The L-shaped plate 1201 is fixedly connected to the slide rail 1101. The L-shaped plate 1201 is slidably connected to the plug-in shaft 1202 through a through hole. The plug-in shaft 1202 is fixedly connected to the retaining ring 1203. The plug-in shaft 1202 is sleeved with a spring 1204. The spring 1204 is located between the L-shaped plate 1201 and the retaining ring 1203. The slide 1102 is provided with a plurality of retaining rings. There are several plug-in holes evenly spaced apart. During actual use, pull the plug-in shaft 1202 until the plug-in shaft 1202 moves out of the plug-in hole. At this time, slide the slide plate 1102 as needed. When the slide plate 1102 slides to the appropriate position, release the plug-in shaft 1202. Under the elastic force of the spring 1204, the plug-in shaft 1202 is inserted into the plug-in hole, thereby limiting the slide plate 1102, effectively preventing the slide plate 1102 from sliding randomly after sliding to the appropriate position. Example 4:
[0030] The same points as the above embodiment will not be described in detail, but the differences are as follows: In this embodiment, referring to Figure 1 、 Figure 3 and Figure 9A controller 9 is mounted on one side of the upper end of the wheelchair frame 1. The controller 9 is electrically connected to a single-chip microcomputer 8 (the principle of the single-chip microcomputer 8 refers to the working principle of a microcomputer that integrates a central processing unit, memory, and multiple input and output interfaces on a single chip. Since it is an existing device, it will not be described in detail here). The single-chip microcomputer 8 is electrically connected to the first motor 302, the second motor 503, the third motor 702, and the electric push rod 1003. The single-chip microcomputer 8, as a microcontroller 9, has powerful data processing and control capabilities. The controller 9 controls the single-chip microcomputer 8. The single-chip microcomputer 8 can be programmed to precisely control the first motor 302, the second motor 503, the third motor 702, and the electric push rod 1003. In turn, it can control the movement speed of the wheelchair frame 1, the adjustment angle of the seat back 6, and the bending and turning movements of the arms, thereby achieving subtle adjustment and precise control. This high-precision control helps meet the personalized needs of different patients and improves user comfort and safety. Example 5:

[0032] The working principle of the arm rehabilitation training device for medical care and nursing of the present invention is as follows: when a patient's arm needs rehabilitation training, the patient sits on the seat 2 on the wheelchair frame 1 with his feet placed on the footrest 4. The controller 9 transmits a signal to the single-chip microcomputer 8. After analysis and processing by the single-chip microcomputer 8, the second motor 503 is controlled. The second motor 503 drives the worm 502 to rotate, the worm 502 drives the turbine 501 to rotate, the turbine 501 drives the rotating rod 504 to rotate, and the rotating rod 504 drives the chair back 6 to rotate, thereby adjusting the angle of the chair back 6. When the angle is adjusted to a comfortable state for the patient, the second motor 503 is turned off. At this time, the patient's arm is placed on the rear arm support 704 and the forearm support 705, and the hand holds the grip 707. At this time, the controller 9 transmits a signal to the single-chip computer 8. After analysis and processing by the single-chip computer 8, the third motor 702 is controlled. The third motor 702 can rotate the rotating frame 703, and then the patient's arm can be bent and turned. By controlling the electric push rod 1003, the electric push rod 1003 can drive the straight tooth plate 1002 to move up and down. Through the cooperation of the gear 1001, the rear arm support 704 can be flipped, and then the patient's arm can be flipped, so that the patient's arm can be bent and turned. When the patient needs to move, the controller 9 transmits a signal to the single-chip computer 8. After analysis and processing by the single-chip computer 8, the first motor 302 is controlled. The first motor 302 drives the rear drive wheel 301 to rotate. Through the cooperation of the front drive wheel 303 and the auxiliary wheel 304, the wheelchair frame 1 moves, and the patient can move as needed.
