Referring to fig. 3 and 4, fig. 3 and 4 respectively show a schematic structural view of the connecting link 21 and a schematic structural view of the connecting member 22 in the present embodiment.

The chain assembly 20 in this embodiment is comprised of connecting links 21 and connecting members 22. The connecting links 21 and the connecting pieces 22 are connected in a staggered manner, every two connecting links 21 are connected through the connecting pieces 22, and correspondingly, every two connecting pieces 22 are connected through the connecting links 21. The connection between the connecting link 21 and the connecting piece 22 is an articulated connection, in particular a rotary connection in the present embodiment. By rotational connection is meant that the connection between adjacent connecting links 21 and connecting pieces 22 is at least rotatable, which also allows a range of allowed translational movements between adjacent connecting links 21 and connecting pieces 22. The rotational connection is for the purpose of converting the chain assembly 20 from a flat state when not worn to a bent state when worn, or from a bent state when worn to a flat state when not worn.

The connecting portions 212 on the connecting links 21 are disposed on two opposite ends of the connecting links 21, wherein the two opposite ends are the ends in the width direction of the chain assembly 20. The connecting portions 212 provided at both ends ensure symmetry and stability of the connection of the chain assembly 20.

The width direction of the chain assembly refers to the vertical direction of the bendable direction of the chain assembly, and correspondingly, the bendable direction of the chain assembly can also be referred to as the length direction of the chain assembly, rather than the length and width of the chain assembly in the dimension. Generally, the dimension of the chain assembly in the length direction is always larger than that in the width direction, but the opposite is not excluded, and the embodiment is not limited thereto. Since the chain assembly in this embodiment can be adjusted according to the increase or decrease of the connecting links and the connecting members, the length and width of the chain assembly in terms of size are variable.

The connecting part 212 and the connecting part 22 form a rotating connection, the rotating connection can be a hinge connection, and the rotating connection between the connecting part 212 and the connecting part 22 can be realized through a hinge connection shaft by respectively arranging hinge connection holes on the connecting part and the connecting part; or, a connecting shaft is arranged on the connecting part 212 or the connecting part 22, and a connecting hole is arranged on the other connecting part, so that the connecting shaft and the connecting hole are matched to realize rotating connection, wherein the connecting shaft can be fixedly connected with the connecting part 212 or the connecting part 22, for example, through interference fit, or fixedly connected through gluing, welding, integral forming and the like. Here, the rotation connection between the connection portion 212 and the connection member 22 is used to realize the rotation therebetween, and may have no limit function or may be provided with a limit function to some extent, that is, the size of the hinge connection hole is set to be larger than that of the hinge connection shaft.

In order to realize the spacing effect of chain subassembly when wearing, can realize spacingly through limit structure. Wherein, limit structure specifically passes through: an extension part 221 is arranged at the position where the connecting part 22 is rotatably connected with the connecting part 212, the extension direction of the extension part 221 extends inwards along the width direction of the chain assembly, the top surfaces of the extension part 221 and the link body 211 of the connecting link 21 are respectively and correspondingly provided with a limiting column 41 and a limiting hole 42, the extension direction of the limiting column 41 is the height direction of the chain assembly, and the limiting column 41 is positioned in the limiting hole 42; in order to achieve the limiting effect, the size of the limiting column 41 is smaller than the size of the limiting hole 42, the limiting column 41 is located in the limiting hole 42, the limiting hole 42 can provide a moving space for the limiting column 41, and the moving space of the limiting column 41 realizes the limitation of the rotational connection between the connecting link 21 and the connecting member 22. The extension 221 is oriented to extend inward along the width of the chain assembly so that the retainer structure is hidden inside the chain assembly to maintain the integrity and aesthetic appearance of the chain assembly. Referring to fig. 5, fig. 5 is a top view of the connecting member provided in the present embodiment, when the position-limiting pillar 41 moves to a point a in the position-limiting hole 42, the movement of the position-limiting pillar 41 in the position-limiting hole 42 reaches a boundary, an angle between the connecting member 22 and the connecting link 21 under the boundary is a first angle, and the connecting member 22 and the connecting link 21 reach a flat state at the limit under the first angle, and do not exceed the state to cause a reverse folding; when the position-limiting column 41 moves to the point B in the position-limiting hole 42, the movement of the position-limiting column 41 in the position-limiting hole 42 reaches another boundary, the angle between the connecting member 22 and the connecting link 21 at the boundary is a second angle, and the connecting member 22 and the connecting link 21 reach a maximum bending state at the second angle without exceeding the state to cause excessive bending. Thus, the range from the first angle to the second angle, which is the predetermined angle range defined by the engagement between the position-limiting post 41 and the position-limiting hole 42, does not exceed the bending range between each adjacent connecting link 21 and connecting member 22 in the chain assembly 20. Generally speaking, the limit state of the chain assembly 20 at the first angle is a flat state, and the limit state of the chain assembly 20 at the second angle is a wearing state, and a reasonable angle can be set by referring to the shape and thickness of the wrist, or the angle range can be customized according to the wrist of different people, so that the wrist can fit different users.

The limiting columns 41 and the limiting holes 42 are arranged in one group, and the limiting effect can be further improved by arranging the limiting columns 41 and the limiting holes 42 on the two sides of the connecting link 21 and the connecting piece 22. Of course, when two sets of the position-limiting columns 41 and the position-limiting holes 42 are provided, the same set of the connecting parts 212 and the position-limiting columns 41 and the position-limiting holes 42 on the connecting parts 22 should be symmetrically provided.
