In actual use, when external force is applied to the sliding slot 342, the adjusting ear 341 is pulled or pushed, and under the rotating cooperation of the deep groove ball bearing 33, the adjusting ear 341 drives the adjusting fork 34 to rotate and rotate around the center of the rotating shaft 32.

[0036] More preferably, referring to Figure 2 and Figure 4 , the driving assembly 2 comprises a guide rod motor 21 arranged on the upper end face of the mounting base 1. The guide rod motor 21 is connected to the adjusting arm fork 22 at the output end.

[0037] In the embodiment, the guide rod motor 21 is fixed to the upper end face of the mounting base 1 through the motor mounting seat. The adjusting arm fork 22 is connected to the output end of the guide rod motor 21, so that when the output end of the guide rod motor 21 is pushed out or retracted, the adjusting arm fork 22 moves radially with the output end of the guide rod motor 21.

[0038] Further preferably, referring to Figure 4 , the adjusting arm fork 22 is a U-shaped fork, and an adjusting shaft 23 is arranged between the two sides of the front end of the adjusting arm fork 22. The adjusting arm fork 22 slides in the two sliding grooves 312, and the adjusting shaft 23 slides in the slot of the two sliding grooves 312.

[0039] When the guide rod motor 21 is controlled by the motor controller and is pushed out or retracted, the connecting arm 22 and the output end of the guide rod motor 21 are adjusted, so that the connecting arm 22 can be reciprocatingly pushed out or retracted in the sliding groove 312, the adjusting shaft 23 can slide in the slot, and when the adjusting shaft 23 is installed, the adjusting shaft 23 passes through the sliding slot 342, so that when the connecting arm 22 is pushed out or retracted, the adjusting shaft 23 can drive the adjusting lug 341 to move, and under the rotating connection of the deep groove ball bearing 33, one end of the adjusting front fork 34 can be pulled by the adjusting lug 341 to rotate around the rotating shaft 32 by 90 degrees or less, thereby adjusting the support angle of the support seat 35.

[0040] Further, the power connection mode of the guide rod motor 21 is a prior art, and the control circuit can be realized by simple programming of those skilled in the art, which belongs to the common knowledge in the art, and only the use is described, without modification, so the control mode and circuit connection are not described in detail. The user can program the frequency of the reciprocating drive of the guide rod motor 21 to control the extension distance, complete the angle adjustment of the adjusting front fork 34, and when the output end of the guide rod motor 21 is not reciprocatingly driven, the support seat 35 can be used to adjust the angle of the arm support for the elderly.

[0041] Further, referring to Figure 1 , Figure 2 and Figure 3 , the oil buffer 4 is arranged on the upper end surface of the mounting base 1, and the top end of the oil buffer 4 abuts against the bottom surface of the support seat 35.

[0042] When the support seat 35 is adjusted and rotated to a horizontal state, the support seat 35 can be buffered and unloaded by the oil buffer 4, and the oil buffer 4 can make the support seat 35 more comfortable when supporting the arm of the elderly.

[0043] More specifically, referring to Figure 5 , the outer wrapping layer of the soft pad 38 is a cotton pad, and the inside of the cotton pad is filled with medical sponge.

[0044] In actual use, the medical staff places the soft pad 38 on the upper end surface of the support seat 35, and then uses the buckles 36 and the elastic bands 37 to elastically fix the soft pad 38. The binding of the soft pad 38 by the elastic bands 37 makes the support seat 35 not easy to fall. The medical sponge filled in the soft pad 38 has the characteristics of softness and elasticity, and can provide a comfortable cushioning experience. By wrapping the medical sponge in the cotton pad, the softness and comfort of the soft pad 38 can be further increased, the pressure and discomfort of the old people's arms can be reduced, the direct contact between the arms and the support can be effectively reduced, the support pressure and sliding friction of the old people can be reduced, the risk of skin damage of the old people can be reduced, and the cotton pad and the medical sponge are relatively easy to clean and maintain. The cotton pad can be washed regularly to keep it clean and sanitary, and the medical sponge can be replaced as needed to maintain the hygiene and performance of the soft pad 38.

[0045] Working principle

[0046] The arm support structure of the old-age rehabilitation nursing robot:

[0047] First step: when the old people use the nursing support structure, the soft pad 38 is placed on the upper end surface of the support seat 35, and then at least two groups of buckles 36 and elastic bands 37 are used to elastically fix the soft pad 38. The binding of the soft pad 38 by the elastic bands 37 makes the support seat 35 not easy to fall;

[0048] Second step: after the soft pad 38 is bound, the medical staff assists the old people to place the small arm on the upper end surface of the soft pad 38. The power switch of the guide rod motor 21 is turned on, so that the output end of the guide rod motor 21 drives the adjusting arm fork 22 to slide forward radially. Through the sliding of the adjusting arm fork 22 in the sliding groove 312 and the sliding of the adjusting shaft 23 in the sliding slot 342, the adjusting front fork 34 can be driven to rotate around the center of the rotating shaft 32 within 90 degrees through the pulling of the adjusting shaft 23. Through the fixing between the adjusting front fork 34 and the support seat 35, the user controls the reciprocating radial sliding out and retraction of the output end of the guide rod motor 21. Finally, when the old people's arms are placed on the soft pad 38, the support seat 35 can drive the old people's arms to reciprocatingly lift within 90 degrees around the center of the rotating shaft 32, thereby realizing the rehabilitation training of the old people's arm muscles. When the output end of the guide rod motor 21 is not reciprocally driven, the support seat 35 can also be used to support the old people's arms at an adjustable angle according to the needs of the old people.

[0049] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
