Abstract: A transmission mechanism for a doll is arranged on a top stage of the doll and comprises a motor fixed to the top stage, a pulley set linked to the motor, a gear set having a plurality of gears and linked to the pulley set, a link having one end eccentrically connected to one gear in the gear set, and a swing rod pivotally arranged on the top stage by a center part thereof. The link has another end connected to the swing rod and the swing rod has two limbs on two opposite ends thereof. The limbs have alternative swing motion due to a seesaw motion of the swing rod. Therefore, the arms of the doll can be swung lively by the limbs.

Abstract: A telescopic doll structure comprises a base, a top stage, and a telescopic rack.
