Patent ID: 8904601

Claim:
A synchronous movement device applied to dual-shaft system, comprising: a first shaft having a fixed end and a pivoted end; a driver disposed at the pivoted end of the first shaft; a second shaft having a fixed end and a pivoted end; a reactor disposed at the pivoted end of the second shaft; and a link unit disposed on the first and second shafts and connected with the driver and the reactor, the driver being rotatable with the first shaft to push the link unit to move along the first and second shafts so as to make the reactor rotate in a direction reverse to a moving direction of the driver, whereby the first and second shafts are synchronously rotated; wherein the link unit includes a first main body and a second main body assembled on the first and second shafts respectively, the first and second main bodies being connected with each other; and each of the first and second main bodies has a main end and a subsidiary end, the main end of the first main body being in contact with the driver, while the subsidiary end of the first main body being in contact with a subsidiary driver disposed at the pivoted end of the first shaft and rotatable therewith, the main end of the second main body being in contact with the reactor, while the subsidiary end of the second main body being in contact with a subsidiary reactor disposed at the pivoted end of the second shaft and rotatable therewith.
