[0002] Shadowless lamps are used during surgery, but commonly used shadowless lamps are used to illuminate the surgical site. However, most shadowless lamps currently only serve the purpose of lighting, and the light of many shadowless lamps is blocked by the shadow of the robotic arm, causing the surgeon to constantly adjust the position of the shadowless lamp to solve this problem. Therefore, when using a surgical shadowless lamp, its rotating arm needs to be able to rotate at multiple angles to adapt to different surgical requirements.

[0003] The existing surgical shadowless lamp can be rotated and adjusted at multiple angles during use. However, when the rotating shaft is used for rotation adjustment, the tightness accuracy of the assembled rotating shaft cannot be adjusted, resulting in the rotation action not being able to run smoothly during the angle rotation of the rotating shaft, which has a certain impact on the efficiency and accuracy of the surgical shadowless lamp adjustment. Therefore, we need to propose a connection structure for the rotating shaft of the surgical shadowless lamp. Utility Model Content
