Thirdly, unlike the first and second embodiments, in which the T-shaped steel plate 32 is located at a different position from the link 31 of the link 31, the straight surface 321 of the T-shaped steel plate 32 is located below the lower surface of the upper end 311 of the link 31, and extends upwards along the straight surface 321 to form a vertical member 322, as shown in fig. 10, that is, the T-shaped steel plate 32 is inserted from below the upper end 311 of the link 31 to support the link 31 and provide a supporting function for the link 31.

In the present embodiment, the first and second forms of T-shaped steel plate 32 are riveted on the chain link 31, the flat surface 321 includes two first limiting holes 321a, and the connection between the T-shaped steel plate 32 and the chain link 31 is realized by rivets and the first limiting holes 321a and the corresponding second limiting holes on the upper end 311 surface of the chain link 31. The third form of T-shaped steel sheet 32 and the link 31 may be connected by riveting or welding.

The links 31 and the T-shaped steel plates 32 in this embodiment may be manufactured by punching, cutting, or the like.

Preferably, wearable equipment in this embodiment includes smart watch, intelligent bracelet etc. and it has flexible screen module wherein smart watch and intelligent bracelet, can carry out deformation in the scope of buckling that allows.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, article, or apparatus that comprises the element.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
