Abstract: This invention relates to a dynamic toy device, which can extend and shrink vertically, turn horizontally, and can be used as a framework of a Christmas tree model. It includes a bottom basin, a drive part in the bottom basin, and a dynamic part on the drive part. The dynamic part includes an inner sleeve group in the center and an outer sleeve group outside the inner sleeve group. The outer sleeve group is composed of several outer sleeves coupling one another. A circle protruding inward is set on the inner side at the top of the outer sleeve. A circle protrudes outwardly and is positioned at the outer side at the bottom of the outer sleeve. On the side of the circle at the top of the outer sleeve, there is a protruding block, while on the outer side of the outer sleeve, there is positioned a rising groove of a curve shape. The block on the outside outer sleeve lies in the groove on the abutting inside outer sleeve.
