Description

TECHNICAL FIELD

[0001] The utility model relates to a toy connecting element, especially to a spherical connecting element in a splicing toy, and belongs to the technical field of toys. BACKGROUND

[0002] In the splicing toy, the spherical element is a common element, because the contact surface between the spherical element and other elements is lower when splicing, so the spherical element generally has a mechanical connecting structure, such as a plug-in hole, and the extension of the model or the connection between other elements is realized by means of a rod or stick type element inserted into the plug-in hole, such as a combination toy connecting piece disclosed in CN210933793U, which is such an element. Because this kind of element needs to have a connecting structure, the plug-in hole is generally a blind hole, and if it is a through hole, it is easy to interfere when inserted from multiple directions, so the plug-in hole cannot be too shallow, and therefore it is difficult to make the element very small in size. Moreover, the mechanical connecting structure needs to be connected by means of a rod or stick type element, in order to ensure the stability after connection, some elements also involve a locking mechanism, which further increases the size and complexity of the element, and it is generally difficult to adjust the angle after connection with other elements.
