Single dynamic source controlled two groups of hands in clockwise/anticlockwise rotating structure

Abstract

A single dynamic source controlled two hands group in clockwise/anticlockwise rotating structure, which sets two groups of numbered face in reverse direction on face of wristwatch, each numbered face has hour, minute and second hand, wherein active shaft of one hands group is driven by active gear, and passive shaft of another hands group is driven by passive gear, diameter, number of teeth and clearance of tooth of passive gear are as same as active gear; one driving gear drives active gear to rotate, and this active gear meshes with two steering gears to drive another hands group to rotate in reverse direction, thus, one hands group rotates clockwise and another hands group rotates anticlockwise. So that, it is interesting to watch time on your wristwatch, moreover, owing to the anticlockwise arrangement of hands group and numbered face, user can directly confirm the left time as required and the wristwatch can display kinds of time according.

Claims

1. A single dynamic source controlled two groups of hands in clockwise/anticlockwise rotating structure, the features are as follows: Two groups of numbered face and arranged in reverse direction are set on face of wristwatch, each numbered face has hour, minute and second hand, wherein active shaft of one hands group is driven by active gear and passive shaft of another hands group is driven by passive gear, diameter, number of teeth and clearance of tooth of passive gear are as same as active gear; one driving gear drives active gear to rotate, and this active gear meshes with two steering gears to drive another hands group to rotate in reverse direction, thus, one hands group rotates clockwise and another hands group rotates anticlockwise. So that, it is interesting to watch time on your wristwatch, moreover, owing to the anticlockwise arrangement of hands group and numbered face, user can directly confirm the left time as required and the wristwatch can display kinds of time accordingly.

2. As claimed in claim 1, wherein said two groups of numbered face in reverse direction can be arranged in upper and below or left and right alignment.

3. As claimed in claim 1, wherein said two groups of numbered face in reserve direction can be arranged according to their sizes.

4. As claimed in claim 1, wherein said two groups of numbered face in reserve direction can be set as main and secondary face in practical application.
