When the adjusting rod 25 rotates back and forth, the card block 31 will be stuck with the indirect gear 27 during the counterclockwise rotation, resulting in the pushing of the indirect gear 27. When the card block 31 rotates clockwise, since the tooth groove of the indirect gear 27 is inclined, it will fall off into the next tooth groove of the indirect gear 27 during the clockwise rotation, thereby pushing the indirect gear 27 to rotate little by little. The indirect gear 27 is connected to the rotating shaft 26. After the indirect gear 27 rotates, the movable gear 28 will be rotated through the rotating shaft 26, and the rotation of the movable gear 28 will move the lifting rod 29 up and down, thereby pushing the lifting armrest box 7 to rise to a suitable position to provide support for the patient's arm.

After the lifting armrest box 7 rises to a certain extent, since the lifting armrest box 7 is located at the outer end of the bed, the upper end of the lifting armrest box 7 can be moved inward by manual shifting, so as to facilitate the patient's arm support. When things need to be stored, the folding plate 32 can be opened and the two folding plates 32 can be folded relative to each other to form a storage table for storing things.
[0034] Working principle: When the home nursing bed 1 is used for a patient to lie on the bed, the patient needs to sit up or lie down. During the use of the home nursing bed 1, the lifting frame 8 needs to be lifted by the operation of the driving motor 4 through the lifting device, thereby driving the entire bedside lifting plate 2 to be lifted, and the backrest of the person is lifted by the bedside lifting plate 2, so that the whole body of the person sits up. After the patient sits up, the whole body of the person will rise. At this time, the arms on both sides need to be supported by the lifting armrest box 7. When the patient needs arm support, the adjusting rod 5 can be manually adjusted by the adjusting device in the linkage device to adjust the start of the lifting armrest device, so as to avoid using the lifting armrest device to lift the lifting armrest box 7, and provide the patient's hands for support; When the lifting device needs to be started, the driving motor 4 is started by remote control, so that the driving motor 4 drives the threaded rod 11 to rotate. When the threaded rod 11 rotates, the telescopic column 10 cannot rotate because the position of the telescopic column 10 is fixed and the telescopic column 10 and the connecting block 9 are movable. Therefore, when the telescopic column 10 is rotated by the threaded rod 11, the telescopic column 10 will gradually move parallel to one side. During the movement of the telescopic column 10, the moving block 9 also moves, thereby changing the angle of the connecting block 9. Since the connecting block 9 and the lifting frame 8 are in a fixed state, after the angle of the connecting block 9 changes, the lifting frame 8 also rotates, thereby raising the entire bedside lifting plate 2 to provide a sitting position for the patient. After the patient is sat up by the bedside lifting board 2, if the patient needs to support his arms, the adjusting rod 5 is swung to drive the second adjusting rod 13 to swing, so that the second adjusting rod 13 rotates. During the rotation of the second adjusting rod 13, the connecting rod 15 also moves. The movement of the connecting rod 15 will push the pressing rod 16 to swing. When the pressing rod 16 rotates, the pressing rod 16 will be set vertically. The pressing rod 16 in the vertical state will press the swing rod 19 to change the position of the swing rod 19, so that the tooth groove at the lower end of the swing rod 19 and the connecting rod 15 are aligned. When these preparations are in place, the start of the drive motor 4 will drive the threaded rod 11 to rotate. When the threaded rod 11 rotates, the bevel gear 22 at the outer end will be driven to rotate, thereby rotating the second bevel gear 23. The second bevel gear 23 rotates and drives the movable shaft 14 to rotate, thereby rotating the second adjusting rod 13. The rotation of the second adjusting rod 13 will push or pull the swing rod 19 to move left and right. After the swing rod 19 moves left and right, since the swing rod 19 is meshed with the connecting gear 33, the connecting gear 33 will be rotated left and right. When the lifting armrest box 7 needs to be lifted, the adjusting rod 25 will rotate repeatedly with the back-and-forth rotation of the sleeve rod 24. A clamping block 31 is installed on the adjusting rod 25, and the clamping block 31 is meshed with the indirect gear 27. When the adjusting rod 25 rotates back and forth, the clamping block 31 will be stuck with the indirect gear 27 during the counterclockwise rotation, resulting in the pushing of the indirect gear 27. When the clamping block 31 rotates clockwise, since the tooth groove of the indirect gear 27 is inclined, it will fall off to the next tooth groove of the indirect gear 27 during the clockwise rotation, thereby pushing the indirect gear 27 to rotate little by little, and the indirect gear 27 is connected to the rotating shaft 26. Then, after the indirect gear 27 rotates, the movable gear 28 will be rotated through the rotating shaft 26, and the rotation of the movable gear 28 will move the lifting rod 29 up and down, thereby pushing the lifting armrest box 7 to rise to a suitable position to provide support for the patient's arms. After the lifting armrest box 7 rises to a certain extent, since the lifting armrest box 7 is located at the outer end of the bed, the upper end of the lifting armrest box 7 can be moved inward by manual manipulation, thereby facilitating the patient's arm support. When things need to be stored, the folding plate 32 can be opened and the two folding plates 32 can be folded relative to each other to form a storage table for storing things.
