Abstract: An automatic adjusting device for position of center of gravity of an object is disclosed. The device comprises a weighing element, an elastic element, a base seat, a hollow tube body, characterized in that one end of the weighing element is connected with the elastic element and the base seat such that the weighing element, the elastic element and the base seat are positioned within the hollow tube body, the C.G of the device is located at the handle region of the device and in application, the tube body is rapidly swung and the weighing element produces a centrifugal force a lot greater than the elastic element and the weighing element is instantaneously moved to the front end of the tube body and the C.G will move simultaneously, when the swinging force of the tube body is released, the pulling force of the elastic element will cause the weighing element to restore to its original position and the C.G. is simultaneously restored to its original position, thereby the C.G.

Abstract: An automatic adjusting device for adjusting the position of the center of gravity of an object comprises a weighting element, an elastic element, a base seat, and a hollow tube body. One end of the weighting element is connected to the elastic element and another end of the elastic element is connected to the base seat, such that the weighting element, the elastic element and the base seat are positioned within the hollow tube body. Initially, the C.G. of the device is located at the handle region of the device, and when the tube body is rapidly swung, the weighting element produces a centrifugal force that is greater than the force of the elastic element to move the weighting element to the front end of the tube body and move the C.G. simultaneously. When the swinging force of the tube body is released, the pulling force of the elastic element will cause the weighting element to be restored to its original position, and the C.G. will be simultaneously restored to its original position as well.
