step S1, when the hook component is in a working state, the hanging buckle (2) is in the first cavity (43), the fourth wedge (64) limits the hook component to rotate through the pretightening force of the first return spring (5) and the first limit (41), and the hook component limits axial movement through the base (4) and the first sliding pin (6);
step S2, when the hook assembly enters a storage state, the hanging buckle (2) is driven by the hook (1) to rotate, the convex edge pushes away the first sliding pin (6) through the inclined surface of the fourth wedge (64) and rotates to one side of the second limit (42), the hanging buckle (2) pushes away the first sliding pin (6) and the second sliding pin (7) through the first wedge (61) and the fifth wedge (71) and enters the second cavity (44), the first sliding pin (6) and the second sliding pin (7) reset under the action of the first return spring (5) and the second return spring (8) and limit the hanging buckle (2) to return to the first cavity (43), and the hook assembly is stored;
step S3, when the hook assembly returns to the working state, the convex edge rotates to push away the second wedge-shaped (62) inclined surface and rotates to the first blocking edge (65), the convex edge pushes away the first sliding pin (6) through the third wedge-shaped (63) inclined surface under the driving of the pull force of the hook (1) and enters the first cavity (43), the first sliding pin (6) is reset through the first reset spring (5) and limits the hanging buckle (2) to return to the second cavity (44), and the hook assembly works.
