The utility model provides an operation microscope rotating device, which can adjust the front and back of a lens body through a second rotating assembly, in order to make the operation of a user more comfortable and flexible when a lens swings back and forth, the utility model places a rotation center A of a second rotating arm on a vertical line of a gravity center B of the lens, and the rotation center A is as close to the position point of the gravity center B as possible, so that a pendulum effect in a horizontal state can be obtained, namely, the lens is in a horizontal state in a natural state, the closer the distance H between the gravity center B of the lens and the rotation center A of the second rotating arm is, the smaller the gravity moment when the lens swings back and forth is, the smaller the force when the operator rotates back and forth to adjust the angle of the lens is, and the adjustment is easy and flexible.

6. According to the operation microscope rotating device provided by the utility model, the polytetrafluoroethylene damping block is adopted in the second rotating assembly, and due to the fact that polytetrafluoroethylene is made of a non-rigid material, when the pressure applied to the polytetrafluoroethylene damping block is increased, the friction force generated between the polytetrafluoroethylene damping block and the shaft boss is linearly increased, the phenomenon that the damping block and the shaft boss are locked due to the friction force generated between the conventional metal damping block and the shaft boss directly caused by the pressure is avoided, namely the friction force generated between the polytetrafluoroethylene damping block and the shaft boss can reach a balance point, the balance point can enable a user not to drop down suddenly after the second locking knob is loosened, the safety and the reliability are greatly improved, and the adjustment is more labor-saving and flexible. In the second rotating assembly, the polytetrafluoroethylene damping block has a first damping effect on the central rotating shaft; by rotating the second locking knob 212, the locking rod on the second locking knob tightens the third hoop, and the third hoop embraces the shaft boss to generate a braking friction force, which serves as a second damping action. The first damping function has a large adjusting range, and the endoscope body cannot drop suddenly when a doctor does not tighten the second locking knob, so that the safety and the reliability are good.
