Abstract: A protruding tongue and sounding structure of a puppet includes a protruding tongue and sounding device mounted inside the puppet. The puppet is a soft and hollow bag-shaped configuration. The protruding tongue and sounding device includes a housing and a slide member which is movable in the housing by air flow. A whistle is provided in the slide member. The slide member includes a tongue at one end thereof. The tongue can extend out of the slide member and the puppet. When the puppet is pressed by the user's fingers, the air in the puppet flows out through the protruding tongue and sounding device. The air in the puppet pushes the slide member of the protruding tongue and sounding device to move outward and forces the whistle to sound. Furthermore, the tongue extends outward, like the puppet to protrude its tongue.

The first gear engages with the second gear. The second gear has at least one waved portion thereon. The position of the turning member is changed by movement of the waved portion to open and close the top lid with respect to the main body, providing visual and sound effects. The elastic piece is located beside the first gear or the second gear. The elastic piece can sound along with rotation of the gears. The pencil sharpener of the present invention has visual and sound effects to attract consumers.

Abstract: A rotating structure capable of revolution and rotation includes a base, a gear device mounted on the base, and an ornament coupled to a rotation shaft of the gear device. The present invention uses the gear device to turn the ornament. The gear device has another rotation shaft fixed to the base. When an external force is applied to turn the gear device, the gear device will generate power for the ornament to rotate itself and to move around, providing a dual effect of rotation and revolution. By the difference between the two rotational speeds, the present invention provides a novel vision effect.

Abstract: An internal rocking structure applied in eyeball of the puppet includes an outer casing made of a transparent material, an inner casing, and an elastic member; the inner casing being connected to the elastic member, which is connected to a bottom of the outer casing; a pattern of an eyeball being printed on where appropriately on the inner casing; upon shaking the rocking structure, the elastic member maintaining the inner casing in a rocking status for a given time to deliver amusing effects of a rocking eyeball and significantly increase bizarrely lovable effects when applied in a puppet or doll.

Abstract: A triggering structure provided in a housing includes a circuit body, a pillar, an elastic part, a light-emitting part, and a power supply unit. Part of the pillar in the housing is exposed. When being pushed with an external force to draw back to the inside of housing, the pillar may make the contact points disconnecting from each other in the circuit body, thereby the light-emitting part being made to light; contrarily, when the pillar normally extends out of the housing, the circuit where the disconnected contact points is not turned ON by the pillar is open, and thus the light-emitting part does not work. Depending on a service state, the triggering structure may automatically enable and disable a sound-light part and may be applied to various products.

Abstract: A deformable toy includes: a deformable surrounding wall defining an enclosed space therein and having a foldable portion and an invertable portion; and a decorative piece connected to the invertable portion. The invertable portion is concave relative to the foldable portion so as to cooperate with the foldable portion to define a first recess to receive the decorative piece therein when the foldable portion is disposed at a non-folded state and the invertable portion is disposed at a non-inverted state. The foldable portion defines a second recess, the invertable portion is convex relative to the foldable portion to protrude outwardly of the second recess from the foldable portion, and the decorative piece is disposed outwardly of the second recess when the foldable portion is disposed at a folded state and the invertable portion is disposed at an inverted state.
