Abstract
A transmission device includes a holder, a pivot shaft, and an elastic member. The holder defines a receiving hole. The pivot shaft is received in the receiving hole. The elastic member is received in the receiving hole, fixed to the holder, and tightly enfolds the pivot shaft. When torques applied to the holder or the pivot shaft are larger than a predetermined value, the elastic member is deformed such that the pivot shaft rotates relative to the holder.
