As shown in  FIGS. 1, 21, 22, 24 and 29 , the bracelet assemblys can be combined to form various types of bracelets. 
     The structure of the assembly is simple but integrates a number of important concepts and new elements, comprising: designing a new wrist-wear equipment based on the bracelet assembly, with random structure and appearance, high reliability and durability, easy to assemble and disassemble, easy to tidy and maintain, easy to produce and low cost, and strong follow-up of the design. The production of groove links can make full use of  3 D printing technology to achieve the best results, and can be matched with the current wrist-wear equipment to design new wrist-wear equipments, and can enhance the functions and capabilities of wrist-wear equipments currently on the market. 
     Based on the above points, the structure of the groove link and the opening and closing base must be as simple as possible to obtain the best balance and effect. The design of the groove link and the opening and closing base is corresponding to a multi-unit wrist-wear equipment that uses soft tubes or cables to connect each unit, so it can transmit one or more of currents, electric waves, liquids and gases, etc. between these units. In addition, the common base can be customized to fit a specific unit. With the common base or other matching assemblys or units, more changes can be created. 
     The grooved bracelet is an open structure, so the soft tube or cable in the accommodating groove is in a natural state. There are notches on both sides of the opening and closing base for the soft tube or cable to pass through, so the accommodating chamber of the opening and closing base is not limited to adjusting the length of the soft tube or cable, and it also has the function of mounting other components. Soft tubes or cables can be selectively configured, so multiple different devices can be mounted on the bracelet assembly at the same time. 
     The present invention is not limited to the specific embodiments described above, and various changes made by those skilled in the art based on the above concepts without creative labor fall within the protection scope of the present invention.
