Rotating body structure

A rotating body structure is characterized in that a mandrel is arranged in a rotating body, two ends of the mandrel are respectively provided with a bearing in a pivoted mode, the center of the mandrel vertically extends to form a rotating piece, the rotating piece rotates in a radial centrifugal mode with the mandrel as the axis, and the rotating piece can be further provided with at least one balancing weight. The length of the rotating piece combined with the balancing weight is smaller than the radius of the rotating body; by means of the structure, a user can operate the rotating body at any time and train the hands, the wrists or the feet, and when force is applied to the rotating body, the rotating piece or even combined with the balancing weight can rotate in the rotating body in a silent mode. 一种旋转体结构，于一旋转体内部设有一心轴，该心轴两端分别枢设有一轴承，并该心轴中心垂直延伸有一转动件，该转动件以该心轴为轴心呈径向离心式转动，且该转动件更可设置有至少一配重块，并使该转动件结合配重块的长度小于该旋转体的半径；借由上述结构，使用者可于任何时间操作该旋转体，并进行手部、手腕、或脚部的训练，且当施力于该旋转体时，该转动件、或甚至结合配重块会于该旋转体内部寂静无声地转动。
