The retarding mechanism has a main shaft passed through out of the through hole, and a retarding shaft acting simultaneously with the main shaft. The driving mechanism has a wire wheel fastened on the main shaft. The restoring mechanism has a restoring wheel fastened on the wire wheel. The resistance mechanism has a metal element fastened on the retarding shaft, and a magnetic part is disposed between the metal element and the hollow-out hole, and an interval is formed between the magnetic part and the metal element.
