ABSTRACT:
A structure of clock comprises a main body having a clock mechanism on upper portion, a battery and circuit chamber on medial portion, a pendulum chamber on lower portion and an oscilatory control device on the top thereof. The pendulum has a tubular member at the top having a pair of corresponding right triangular recesses formed at two ends respectively, which are made in registry with the right triangular support members on the oscilatory control device. Because the right triangular support members are sizely smaller than that of the right triangular recesses, it is characterized in that when the triangular recesses suspend from the triangular support members, the oscilatory span of the pendulum is restricted by the oscilatory device.
