Abstract
A transmission device includes a first transmission mechanism comprising a first rotatable member and a first transmission member fixed to the first rotatable member for rotating together with the first rotatable member; and a second transmission mechanism comprising a second rotatable member and a second transmission member fixed to the second rotatable member for rotating together with the second rotatable member. The second transmission member received in the first transmission member, and the second transmission member being magnetically connected with the first transmission member. When a load applied to the first transmission mechanism is less than a predetermined value of the first transmission mechanism, the first transmission member rotates together with the second transmission member by a magnetic force generated therebetween, which in turn makes the first transmission mechanism rotates with the second transmission mechanism together.
