The housing 10 of the present application can also be used in other fields, and only a plurality of the housings 10 are linked together by a simple hinge, for example, the synchronizing assembly 40 is replaced by a simple hinge; similarly, a plurality of the covers 20 can be directly connected to one body by a simple hinge and can be applied to other fields. The folding hand-worn device can be an intelligent bracelet, and the intelligent bracelet further comprises an intelligent watch.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
