Gear two-way clutching mechanism

A gear two-way clutching mechanism affecting between power output and loading and comprising a power source, a loading, a clutching unit and a deceleration unit;

• wherein the power source is provided for power outputting and delivering rotation power to the loading through the clutching unit and the deceleration unit and disposed with a power output shaft;
• the loading having a loading end spindle connected to the clutching unit and the deceleration unit, and of being driven by rotation power outputted from the power source;
• the clutching unit being connected between the power output shaft of the power source and the loading end spindle of the loading and selectively connected to the deceleration unit and transmitting rotation power outputted by the power source to the loading by collaborating with the deceleration unit or disconnecting power of the power source from the loading and enabling the loading to freely rotate, the clutching unit having a first output gear and a buffer gear, the first output gear being coupled to the power output shaft of the power source and the buffer gear being coupled to a stationary shaft between the power output shaft and the loading end spindle, the first output gear having a teeth missing portion and a wheel teeth portion, the buffer gear having gear teeth and capable of being tangential with and corresponding to the teeth missing portion of the first output gear or meshing with the wheel teeth portion of the first output gear, the buffer gear, having a gear axle core and the gear teeth of the buffer gear having a non-rigid connection therewith, the buffer gear having a pierced cutting groove formed circumferentially therein, the pierced cutting groove being formed as a spiral cutting groove or a ring-shaped cutting groove or the pierced cutting groove being distributed to the circumference of the buffer gear by way of heteromorphy and formed as plural cutting grooves;
• the deceleration unit being connected between the power output shaft of the power source and the loading end spindle of the loading and connected to the clutching unit, the deceleration unit transmitting rotation power outputted by the power source to the loading through the clutching unit and disposed with at least two deceleration gears meshed to each other.
