Patent attributes
A multi-axis rotary shaft link device has a simplified structure occupying less room and is easy to assemble. The multi-axis rotary shaft link device includes a transmission unit disposed on a first shaft, a reaction unit disposed on a second shaft and a link unit disposed between the transmission unit and the reaction unit for making the first and second shafts synchronously rotate. The second shaft and a third shaft are assembled with a driven module for rotating the third shaft and a transmission unit disposed on the third shaft. A link unit is disposed between the third shaft and a fourth shaft, whereby the fourth shaft and a reaction unit disposed on the fourth shaft can synchronously rotate with the third shaft. The multi-axis rotary shaft link device can freely rotate around multiple rotational centers, which can be smoothly opened and closed.
