The lifting mode of the lifting rod is in the form of rotation.

The definition of rotation is to rotate a figure around a fixed point in a plane in a certain direction. This graphic movement is called rotation. The essence of rotation is that there are corresponding points between the rotated figure and the original figure, with the same distance from the rotation center and the same rotation angle. The so-called rotation means that an object moves in a circle around a point or an axis. Rotation has a direction, usually divided into counterclockwise rotation and clockwise rotation on the plane. This is easy to understand. The direction of rotation is the same as the clockwise direction in a clock, which is called clockwise rotation, and vice versa.
