The motion axes of the stay rope and the moving soft brush are aligned.
The realization principle is as follows: the stretchable stainless steel cord is wound around a threaded hub to which a precision rotation sensor is attached. When the movement occurs, the pull rope can be stretched and contracted. An internal spring ensures constant tension in the pull cord. The threaded hub drives the precision rotation sensor to rotate. For example, when the pull rope on the front is contracted to drive the soft brush to move rightwards, and after the soft brush reaches the rightmost side, the pull rope on the back is reversely tensioned to pull the soft brush to move leftwards, so that the soft brush is reset.
