Abstract: A connection lock (100) for connection with a watch bracelet. A body portion (110) of the connection lock includes a receiving cavity (111), at least two sliding connection portions (112) and a connection opening (113). The receiving cavity (111) is enclosed by peripheral borders of the body portion (110) to receive a spare length of flexible tube or cable (400), a side border for connection with a bracelet strap (220) provided with a receiving groove (221) being provided with a notch (114) capable of matching the receiving groove (221), so as to enable the flexible tube or the cable (400) in the receiving cavity (111) to pass into the receiving groove (221) from the notch (114). The at least two sliding connection portions (112) are respectively arranged at lower edges of two opposite side borders of the body portion (110). The connection opening (113) is arranged, adjacent to the notch (114), in a side border of the body portion (110) perpendicular to the sliding connection portions (112).

Abstract: The invention discloses a bracelet assembly corresponding to multi-attribute physical connections, which has a groove link, which has a link base and a groove base. There are a first through hole and a second through hole penetrating in a lateral direction and respectively arranged at the two ends of the link base in a lateral direction, and the first through hole and the second through hole are aligned in the lateral direction to form a first axis. And the link base is provided with a first cylindrical portion and a second cylindrical portion, the first cylindrical portion is provided with a first shaft hole penetrating in a lateral direction, and the second cylindrical portion is provided with a second shaft hole penetrating in a lateral direction.
