Abstract
A music bell controlling device of a pearl box comprises a controlling device, a rotary shaft, and a gear set, etc. The gear set is installed between the bottom and base of the music bell. An elastomer is installed at the upper end of the longitudinal axis of the rotary shaft; a base end of the rotary shaft passes through the through hole to combine with the gear set. The upper end of the rotary axis is swingable. The longitudinal axis of the rotary shaft passes through the controlling device; and swinging of the rotary shaft will drive the controlling device to shift so that the controlling device confines the rotation of the music bell flywheel. As the upper cover of the pearl box is closed, the upper cover will drive the rotary axis to shift to a predetermined direction so that the swingable rod of the control device will shift. Thus, the swingable rod contact with the flywheel of music box, and thus, the music bell stops.
