[0025] As shown in Figure 3 , adjusting assembly 2 includes screw rod 21, wedge-shaped push block 22 and motor 23, motor 23 is installed in base 1, control panel 13 is wiredly connected with motor 23, screw rod 21 is rotatably connected in base 1, wedge-shaped push block 22 is slidably connected in base 1, the front end of screw rod 21 is fixedly connected with the output shaft of motor 23, wedge-shaped push block 22 is threadedly connected with screw rod 21, wedge-shaped push block 22 is provided with a rearward inclined surface, the top inclined surface of wedge-shaped push block 22 is extruded with roller 9 at the bottom of support assembly 11, and the rotation shaft of support assembly 11 is located at the rear end.
[0026] As shown in Figure 2 and Figure 4 , locking assembly 3 includes sleeve 31, mounting plate 32, guide rod 33, lock rod 34, return spring 35 and handle 36, sleeve 31 is connected in base 1, return spring 35 is sleeved in sleeve 31, guide rod 33 is slidably connected in sleeve 31 and penetrates the internal space of sleeve 31, mounting plate 32 is connected on the part of guide rod 33 extending out of sleeve 31, lock rod 34 is connected on both sides of mounting plate 32, handle 36 is connected on mounting plate 32, through holes are arranged in base 1 and the bottom of support assembly 11, lock rod 34 is slidably connected through base 1 and support assembly 11, one end of return spring 35 is connected with guide rod 33, and the other end is connected with sleeve 31.
[0027] Medical staff place the nursing device stably on a flat surface, then place the patient's arm on the support component 11, and cushion the transition with the pad 12. The sensor inside the support component 11 is activated through the control panel 13 to adjust the temperature. Then, the support angle of the support component 11 is adjusted according to the surgical position through the adjustment component 2. The softness of the pad 12 can match the angle after the support component 11 is rotated. When the wedge-shaped push block 22 is pressed against the roller 9, it pushes the roller 9 to rotate. After use, the support component 11 is reset through the adjustment component 2 and locked through the locking component 3. Thus, when the device is picked up or moved, the support component 11 can be stably connected to the base 1.
[0028] When adjusting the angle of the support assembly 11, the control panel 13 starts the motor 23, which drives the lead screw 21 to rotate.

When the equipment needs to be used, the mounting plate 32 is pulled out by the handle 36. The mounting plate 32, along with the locking rod 34, disengages from the support assembly 11. At the same time, the guide rod 33 slides in the sleeve 31 and compresses the return spring 35. When the locking rod 34 continues to move outward and disengages from the through hole of the base 1, the handle 36 is rotated. During the rotation of the mounting plate 32 and the locking rod 34, they are pressed against the base 1, thereby maintaining the compressed state of the return spring 35 and not restricting the rotation of the support assembly 11. After the equipment is used, the support assembly 11 is attached to the base 1. At this time, the handle 36 is rotated to align the locking rod 34 with the through hole of the base 1. Then the return spring 35 rebounds, and the guide rod 33 drives the mounting plate 32 and the locking rod 34 to slide, inserting the locking rod 34 into the support assembly 11, thus completing the fixation of the support assembly 11.
