Referring to fig. 7, fig. 7 is an exploded view of another watch chain according to the present embodiment. After the watch chain is assembled, the watch chain of the embodiment further comprises a power steel sheet 601; after the watch chain is assembled, the power steel sheet 601 is arranged in a trapezoidal hole formed by the first connecting part and the third connecting part of the second chain link, the specific arrangement position of the power steel sheet 601 can be seen in fig. 9, and the power steel sheet provides assistance for bending and unfolding of the watch chain. When the watch chain can freely move among all chain links after the assembly is completed, when the watch chain is applied to wearable equipment, for example, some wearable equipment with a flexible screen are required to be bent uniformly, so that the watch chain is added with an elastic steel sheet to ensure that all chain links of the watch chain are bent according to the bending of the elastic steel sheet, the arc transition in the bending process of the watch chain is ensured to be uniform, and meanwhile, the added elastic steel sheet can provide assistance for the bending and straightening processes of the watch chain.

Referring to fig. 7, after the bracelet is assembled, the bracelet of the present embodiment further includes an isolation layer 602; the isolation layer 602 is provided on the upper end surface of the third connecting portion of the second link after the assembly of the bracelet is completed. In this embodiment, the isolation layer 602 is used to isolate and seal the space of the lower layer and the space of the upper layer of the watch chain, and when the flexible display screen is arranged at the upper end of the isolation space, the flexible display screen can be protected and supported, and the specific isolation layer can be made of steel sheets, silica gel and the like.

Referring to fig. 7, the watch chain further includes a silicone sheath 603; after the watch chain is assembled, the silica gel outer sleeve 603 wraps the outer sides of the first chain link and the second chain link, and the contact surface of the silica gel outer sleeve 603 and the first chain link and the contact surface of the second chain link are fixedly connected with the first chain link. Because first chain link and the second chain link on the watch chain that this embodiment provided can move mutually at the in-process of buckling and straightening, and because the shape of first chain link and second chain link is trapezoidal, the gap can appear in the inboard on the watch chain, can see the position of first chain link and second chain link at first connecting portion and second connecting portion in FIG. 7, consequently in order to prevent to get into impurity in the watch chain, need establish the silica gel overcoat at the skin of watch chain and provide the protection, set up this protection overcoat and keep apart the metal part of watch chain and skin when the user wears, increase and wear the comfort level, can also set the silica gel overcoat into the material of class skin matter, further reinforcing user's wearing comfort level. Meanwhile, in the watch chain implemented by the invention, the first chain link is positioned at the outer side of the second chain link, so that the contact surface of the silica gel outer sleeve and the watch chain is fixed with the first chain link, and the silica gel outer sleeve is prevented from falling off.

The embodiment provides a watch chain, which comprises a first chain link, a second chain link and a connecting piece, wherein the first chain link comprises a first connecting part and first supporting pieces respectively arranged at two ends of the first connecting part, the first supporting pieces are trapezoidal in shape with a long upper part and a short lower part, and the upper ends of the first supporting pieces are also provided with a first connecting hole and a second connecting hole; the second chain link comprises a second connecting part and second supporting sheets respectively arranged at two ends of the second connecting part, the second supporting sheets are in a trapezoid shape with a long upper part and a short lower part, and the upper end of each second supporting sheet is also provided with a first connecting hole and a second connecting hole; wherein the second link is slightly smaller than the first link, and the second link can be placed in the first link; when the combination, adopt the first connecting hole and the crisscross alignment of second connecting hole of first chain link and second chain link to rotate the mode of connecting through the connecting piece, the watch chain that the combination goes out is when buckling or straightening, and first connecting portion and second chain link portion draw close or keep away from each other, and the distance between first connecting hole and the second connecting hole does not change, thereby has avoided buckling or straightening the stretching and the extrusion that the flexible screen that the in-process set up the upper end caused.

Second embodiment:

the present embodiment provides a wearable device, and as shown in fig. 8, the wearable device provided by the present embodiment includes a bracelet and a device body provided in the first embodiment.

Referring to fig. 7 and 9, fig. 9 is a cross-sectional view of the bracelet provided in the present embodiment. In this embodiment, the device body further includes a flexible display screen 604; the flexible display 604 is placed over the spacer layer 602 of the bracelet and the neutral layer of the flexible display is aligned with the centre of the links of the bracelet. Wherein the neutral layer of the flexible display 604 is the interface of the flexible display 604 and the spacer layer 602.
