Therefore, they should not be construed as limitations on this utility model.

[0026] like Figs. 1-3 As shown, a novel mechanism for the long-range telescopic extension of a toy head includes a toy lower shell 1, a driven rack 2, and a toy head 23. A motor base 11 is provided at the center of the inner bottom surface of the toy lower shell 1. A slide groove 14 and a motor 12 are provided on the motor base 11. The motor 12 is located on one side of the slide groove 14.

[0027] A support rod 15 is horizontally arranged at the front entrance of the lower shell 1 of the toy. The upper surface of the support rod 15 is flush with the inner bottom surface of the slide 14. The rear end of the driven rack 2 is located in the slide 14, and the front end of the driven rack 2 is located on the support rod 15. The drive shaft of the motor 12 is connected to the drive gear 13 through a coupling. The drive gear 13 meshes with the driven rack 2. In this way, the motor 12 drives the drive gear 13 to rotate, and the drive gear 13 drives the driven rack 2 to move.

[0028] The driven rack 2, away from the slide groove 14, is connected to an adapter 21 via a rotating shaft. The adapter 21, away from the driven rack 2, is provided with a plug 22, and the back of the toy head 23 is inserted into the plug 22.

[0029] The front end of the driven rack 2 is located in the middle of the support rod 15. Two limit blocks 16 are symmetrically arranged on the middle of the upper surface of the support rod 15. The driven rack 2 is located between the two limit blocks 16, so that the back-and-forth movement of the driven rack 2 is relatively stable.

[0030] The toy head 23 is hemispherical, and the plug 22 is arranged at the middle of the plane of the toy head 23, and the plug 22 is rotatable relative to the toy head 23.

[0031] The distance between the two limiting blocks 16, the width of the driven rack 2 and the width of the sliding groove 14 are consistent, so that the driven rack 2 can only move forward and backward and cannot sway left and right.

[0032] The rotation direction of the adapter 21 relative to the driven rack 2 is the up-down direction, and the rotation direction of the toy head 23 relative to the adapter 21 is the circumferential direction; in this way, the toy head 23 can move up and down, move forward and backward, and rotate by itself, and the playability and interest are better.

[0033] The end of the adapter 21 close to the driven rack 2 is provided with a notch, and the front end of the driven rack 2 is rotatably installed in the notch.

[0034] The middle of the plane of the toy head 23 is provided with a plug hole matched with the plug 22.

[0035] As described above: the rear end of the driven rack 2 is located in the sliding groove 14, the front end of the driven rack 2 is located between the two limiting blocks 16, and the support rod 15 supports the front end of the driven rack 2, so that the driven rack 2 is limited in the sliding groove 14 and between the two limiting blocks 16;

[0036] The tooth groove of the driven rack 2 faces upward and engages with the driving gear 13, and the driving gear 13 is connected to the driving shaft of the motor 12 through a shaft coupling; in this way, when the motor 12 rotates, the driving gear 13 can be driven to rotate, and when the driving gear 13 rotates, the driven rack 2 can be driven to rotate; when the driving gear 13 rotates for a number of turns, it can reversely rotate for the same number of turns, so that the driven rack 2 can be moved backward by a distance and then moved forward by a distance;

[0037] The toy head 23 can move backward by a distance and then move forward by a distance along with the driven rack 2, so that the slow reciprocating motion of the toy head 23 is realized;

[0038] The toy head 23 is rotatably connected with the adapter 21, the adapter 21 is rotatably connected with the front end of the driven rack 2, and the adapter 21 and the toy head 23 can rotate in the up-down direction, and the toy head 23 can rotate in the circumferential direction at the front end of the adapter 2; in this way, the toy head 23 can rotate in various directions, and the toy head 23 can also move forward and backward, which has good interest.

[0039] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
