The pawl cooperates with the internal ratchet wheel. The main wheel disc is provided with a protruding extension shaft on one side. The pawl is inserted into the extension shaft of the main wheel disc through a spring. In the initial state, the pawl does not contact the internal ratchet wheel. When the main wheel disc rotates rapidly, the pawl stretches the spring under the action of centrifugal force and expands. When the pawl expands, it contacts the internal ratchet wheel, thereby driving the internal ratchet wheel to rotate synchronously. When the internal ratchet wheel rotates, it will displace. When the internal ratchet wheel reaches the end of the stroke, it will stop moving. The friction force acting on the internal ratchet wheel during movement can slow down the rotation speed of the main wheel disc. When the internal ratchet wheel stops moving, the main wheel disc will stop rotating.
