Description

  The present invention relates to a toy doll, and more particularly to a joint connection structure of a modeling doll that is conveniently attached and detached by freely connecting two connecting surfaces using a fitting column.

  General toy dolls are finished so that they can simulate actual human movements. As the demands on manufacturing technology and realism increase, pivoting or flexing structure designs are employed in the joints of the upper or lower limbs. Many of them employ pivots as pivot axes, and the body parts of toy dolls are equipped with multiple holes corresponding to each part of the body, such as the head, upper limbs, and lower limbs. Since it is assembled and only the head and limbs can turn 360 degrees each, it is not possible to express a rotational motion sensation like a human joint.
