[0005] A resilient rotating assembly includes component I and component II, which are rotatably connected. The main body of component II is a hook, and a spring piece is provided on the hook. The front end of the spring piece engages with the hook tip of the hook to form a safety mechanism. The outer side of the spring piece is smooth. The engaging structure consists of a groove provided at the front end of the spring piece and a protrusion provided at the hook tip of the hook. The groove is a semi-open slot located on the outer side of the spring piece.

[0006] Further refining the above technical solution, a connector is provided on the main body of component I, the connector is located at the lower end of the main body of component I, a groove is provided on the hook, the groove is located at the upper end of the hook; the connector is disposed in the groove and screwed into the groove; the connector is a columnar body with an annular protrusion on its outer periphery, and the groove matches the connector.

[0007] Further refining the above technical solution, the groove has an opening on one side, the size of which is greater than or equal to that of the connector and serves as the connector's inlet / outlet; the hook is provided with an elastic clip A, the snapping part of which extends into the opening, and when the connector enters the groove, it is squeezed by the connector, bypasses the connector, and abuts against the connector, thus forming a stop and limit for the connector entering the groove.

[0008] Further refining the above technical solution, the hook is a plastic part with a hollowed-out side forming an elastic clip A, the snap-fit ​​part of the elastic clip A extending into the connector inlet / outlet.

[0009] To further refine the above technical solution, the snap-fit ​​portion of the elastic clip A is squeezed around the connector head and abuts against the connector head when the connector head enters the groove.

[0010] To further refine the above technical solution, when the snap-fit ​​portion of the elastic clip A is pressed by the connector head, its contact surface with the connector head is an inclined surface.

[0011] Further refining the above technical solution, the main body of component I is a rope buckle.

[0012] Further refining the above technical solution, the elastic rotating assembly also includes component III, the main body of component III being a sealing plug, which is disposed inside the connector inlet / outlet for sealing;

[0013] The sealing plug is provided with an elastic clip B, and the snap-fit ​​part of the elastic clip B hooks onto the hollow part on the side of the hook, thus forming a stop and limit position for the sealing plug.

[0014] Further refining the above technical solution, the sealing plug is provided with a stop bar, the bottom of the groove is left empty, and the end of the stop bar is inserted into the gap at the bottom of the groove and abuts against the side wall of the groove, thus constituting the limit of the sealing plug.

[0015] The advantages of this utility model are that it has a reasonable design and simple structure. When the components are attached to the hook, the spring is pressed inward to open the hook. The outer side of the spring is smooth, so it can be moved along the outer side of the spring and slid into the hook. The operation is simple and smooth. The semi-open groove design eliminates the need for a core-pulling structure when opening the mold, which reduces the cost. In addition, in special circumstances where it is impossible to unlock by pressing the spring, it can be unlocked by pressing from the side. Attached Figure Description
