Three-hour clock

摘要

The present invention relates to a three-hour clock, giving two stages to the hour hand shaft, so that the fixed hour hand at the top, the lower part is provided so that the sliding hour hand can be fitted, and then the hourly fixed time difference adjustment shaft is inserted into the hour hand axis. At this time, a rubber ring is inserted between the hour hand shaft and the parallax adjustment shaft so that the parallax adjustment shaft can be easily rotated at an appropriate force.;A worm gear is installed at the bottom of the jet lag to allow the jet lag to rotate from the outside of the watch case. At this time, the hour hand fixed to the jet lag rotates in the counterclockwise direction, and the sliding hour hand is slid to the desired time by the projection part of the jet lag, and the jet lag moves clockwise to place it at the desired time. If you remove the worm gear at the bottom of the parallax shaft, the differential hour hand shaft does not slip by the rubber ring and rotates with the hour hand shaft at the same time so that the three hour hands move together while maintaining the time difference. It is easy to manufacture and maintains the function of existing analog clock. In addition, the above-described effect can be obtained by providing a plurality of stages on the hour hand shaft, and inserting a plurality of hour hands on each stage at a time difference interval.
