Referring to fig. 3 and 4, the link 10 includes a base 11, a spring 12, and a slider 13. The base 11 is substantially rectangular block-shaped, and the base 11 is opened with insertion holes 11a for engaging the adjacent links 10. The elastic sheet 12 is inserted into the base 11, and two opposite ends of the elastic sheet 12 extend out of the base 11 to be inserted into the insertion holes 11a of the adjacent chain links 10. The sliding block 13 is disposed on the base 11 and configured to slide relative to the base 11 so as to press the elastic sheet 12 and drive the elastic sheet 12 to retract into the base 11.

For convenience of description, the susceptor 11 may be considered to have a first direction and a second direction perpendicular to each other, as shown in fig. 3. The two ends of the chain link 10 in the second direction can be used for connecting adjacent chain links 10, the first direction of the chain link 10 is perpendicular to the second direction, and the two opposite ends of the elastic sheet 12 extend and retract in the first direction. Further, the insertion hole 11a is disposed at one end of the base 11 in the second direction, and the two ends of the elastic piece 12 for extending and contracting are disposed at the other end of the base 11 opposite to the second direction. Under normal use conditions, the opposite ends, i.e., the two free ends, of the elastic sheet 12 extend out of the links 10 and into the insertion holes 11a of the adjacent links 10, thereby achieving connection of the adjacent links 10 and preventing the adjacent links 10 from being easily detached. When the length of the watchband needs to be adjusted, the sliding block 13 can be pushed to move relative to the base 11 so as to extrude the elastic sheet 12 and drive the elastic sheet 12 to retract into the base 11, that is, the two opposite ends of the elastic sheet 12 are separated from the adjacent insertion holes 11a, so that the two adjacent chain links 10 can be detached, and then more than one chain links 10 can be detached to shorten the length of the watchband, or the chain links 10 can be added to prolong the length of the watchband, so as to adapt to the size of the wrist of a user.

When the chain link 10 is applied to a watchband of wearable equipment, because the chain link 10 includes the base 11, the shell fragment 12 and the slider 13, the jack 11a has been seted up to the base 11, the base 11 is stretched out at the relative both ends of the shell fragment 12 and the shell fragment 12 worn to locate by the shell fragment 12 to be used for wearing to establish in the jack 11a of adjacent chain link 10, the slider 13 is located the base 11 and is used for relative base 11 to slide, in order to extrude the shell fragment 12 and drive the shell fragment 12 to retract into the base 11. When the elastic sheet 12 is arranged in the insertion hole 11a of the adjacent chain link 10 in a penetrating manner, the connection of the adjacent chain links 10 can be realized; when the length of the watchband needs to be adjusted, the sliding block 13 can be driven to slide relative to the base 11, so that the sliding block 13 is used for extruding the elastic sheet 12 and driving the elastic sheet 12 to retract into the base 11, and therefore the adjacent links 10 can be detached. The structural arrangement of the chain links 10 can realize convenient disassembly of adjacent chain links 10 so as to conveniently adjust the length of the watchband.

Referring to fig. 3 and 4, in some embodiments, the resilient piece 12 is substantially U-shaped and has a bar shape, and the resilient piece 12 bypasses an end of the slider 13 near the insertion hole 11a from one end of the base 11 in the first direction and extends to the other end of the base 11 opposite to the first direction. Specifically, referring to fig. 3, the elastic sheet 12 may include a first free end 121, a first extending section 123, a deformation section 125, a second extending section 127 and a second free end 129, which are sequentially connected end to end, wherein the first free end 121 and the second free end 129 are oppositely disposed at one end of the base 11 far away from the insertion hole 11a and are used for extending and retracting in the first direction. The first extension 123 bends toward the side of the slider 13 relative to the deformation 125, and the first free end 121 bends toward the side of the insertion hole 11a relative to the first extension 123. The first free end 121 and the second free end 129 may be disposed axially symmetrically about a centerline of the deformation segment 125, and the first extension 123 and the second extension 127 may also be disposed axially symmetrically about a centerline of the deformation segment 125. During the process of extruding the deformation section 125 by the sliding block 13, the axial symmetry arrangement can make the stress on the first free end 121 and the second free end 129 relatively balanced, and can realize the substantially equal stroke of the synchronous movement of the first free end 121 and the second free end 129, so as to facilitate the disassembly and assembly of the chain link 10.

Further, the base 11 may include a base body 111 and a cover plate 113, the base body 111 has a socket 11a, the cover plate 113 covers the base body 111, and at least a portion of the sliding block 13 is slidably fitted between the cover plate 113 and the base body 111. The base 111 may be provided with a sliding slot 11b slidably engaged with the sliding block 13, the cover plate 113 covers the sliding slot 11b, and the elastic sheet 12 penetrates through the sliding slot 11b.
