Abstract:
    The invention relates to radio wave auto timing bell. It includes second hand drive assembly, hour, minute hands drive assembly, and control circuit. The second hand drive assembly includes second hand motor, second magnet wheel, second cross wheel, second hand gear wheel. The hour, minute hands drive assembly includes minute motor, minute magnet wheel, minute cross wheel, minute hand gear wheel, hour cross wheel, and hour hand gear wheel. The second, minute, hour cross wheels and their hand gear wheels are set. The magnet wheel of the motor is set location magnetize mark. The invention uses polarizing pin positioning assemblage to increase assemble speed and precision, magnet wheel positioning assemblage after magnetize to avoid minute, hour hands timing loosely caused by angular degree deviation between magnet N, S poles, stator polarity, and magnet gear wheel, the same motor system to reduce the cost, and many times contrast reading for the minute and second wheels hole site to enlarge reading range, increase pointer positioning accuracy.
