The rotating hand wheel is rotationally connected with the installing base through a rotating shaft. A box is arranged on the installing base. The box is internally provided with a scroll-shaped elastic metal belt. The end of the elastic metal belt extends out of the box and is fixedly connected with the rotating shaft. Due to the fact that the box is arranged on the installing base and internally provided with the scroll-shaped elastic metal plate, and the end of the elastic metal belt extends out of the box and is fixedly connected with the rotating shaft of the rotating hand wheel, when the rotating hand wheel is utilized for carrying out braking or relieving operation, the elastic metal belt can be pulled out of or contracted back into the box, and whether the rotating hand wheel is in a braking position or in a relieving position can be judged according to th
