The width of the limiting groove 7 and the width of the limiting strip 8 are matched. The limiting strip 8 is located inside the limiting groove 7. When the connecting cylinder 3 rotates, it can drive the upper rotating ring 4 to rotate synchronously. When the rotating ring 4 rotates, the lifting rod 5 can be raised or lowered through the thread 6. The limiting strip 8 at the lower end of the lifting rod 5 cooperates with the limiting groove 7 to restrict the rotation of the lifting rod 5. When the lifting rod 5 rises or falls, it drives the mounting base 9 and the elbow support 10 to move up and down.

When the screw 16 rotates, it can drive the elbow support 10 to move through the connector 19. When the elbow support 10 moves, its position can be adjusted to suit the operator's use.

[0034] The base 1 is equipped with a first control button 14 and a second control button 22. The first control button 14 can control the first drive motor 13 to work, and the second control button 22 can control the second drive motor 20 to work.

[0035] This application can be used to support both arms during surgery through two integrated units, or it can be used independently, depending on the surgeon's needs.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In this invention, when the height of the elbow support 10 needs to be adjusted, the first drive motor 13 is started by stepping on the first control button 14. The first drive motor 13 drives the active gear 12 to rotate, which in turn drives the passive gear 11 to rotate. When the passive gear 11 rotates, the connecting cylinder 3 rotates. At this time, the connecting cylinder 3 drives the upper rotating ring 4 to rotate synchronously. When the rotating ring 4 rotates, the lifting rod 5 can be raised or lowered through the thread 6. The limiting strip 8 and the limiting groove 7 at the lower end of the lifting rod 5 cooperate to limit the rotation of the lifting rod 5. When the lifting rod 5 rises or falls, it drives the mounting base 9 and the elbow support 10 to move up and down. The second drive motor 20 is started by the second control button 22. The second drive motor 20 drives the screw 16 to rotate. When the screw 16 rotates, the elbow support 10 can be moved horizontally through the connecting piece 19. When the elbow support 10 moves, its position can be adjusted to suit the operator's needs.
