1. A dual-shaft synchronous transmission device, comprising:
a first shaft having a fixed section and a pivoted section; a second shaft having a fixed section and a pivoted section; a driver having a shaft section and a shaft hole formed on the shaft section, the pivoted section of the first shaft being fitted in the shaft hole of the driver to mount the driver on the pivoted section of the first shaft, a crown gear structure being disposed on the shaft section of the driver; a reactor having a shaft section and a shaft hole formed on the shaft section, the pivoted section of the second shaft being fitted in the shaft hole of the reactor to mount the reactor on the pivoted section of the second shaft, the shaft section of the reactor being parallel to the shaft section of the driver, a crown gear structure being also disposed on the shaft section of the reactor; and a link unit including a shaft section normal to the shaft sections of the driver and the reactor, the link unit further including spur gear structures at two ends of the shaft section, the spur gear structures being engaged with the crown gear structures of the driver and the reactor, whereby via the link unit, the first shaft with the driver and the second shaft with the reactor can be synchronously rotated in reverse directions. |
