The rotating piece 1 arranged in the supporting assembly is rotationally connected with the cavity through a bearing, and can realize smooth rotation under stress. The rotating piece 1 is connected with a volute spring, and the volute spring provides a recovery force for the rotating piece 1. When the rope is stretched, the rope drives the rotating piece 1 to rotate in one direction against the elastic force of the volute spring, and after the rope is released, the elastic force of the volute spring drives the rotating piece 1 to rotate in the opposite direction, so that the automatic recovery of the rope is realized. Through the cooperation of the elastic member and the rotating mechanism, the rope can maintain appropriate tension during use, which not only ensures the flexibility of the high-altitude operation tool, but also effectively prevents the tool from falling accidentally, and improves the safety and convenience of operation.
[0060] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope of the present application.
