Second distance.

In another embodiment, the present invention provides a hook structure including a main body, a hook and a flexible blocking piece. The main body includes a first abutting arc surface and a second abutting arc surface, the first abutting arc surface includes a starting point of the first arc surface, and the second abutting arc surface includes a second arc surface starting point the beginning. The hook is connected to the main body, wherein a hanging notch is formed between the hook and the main body. A flexible blocking piece is arranged on the main body, the flexible blocking piece is suitable for covering at least part of the hanging notch, wherein the flexible blocking piece comprises a blocking piece base, the blocking piece base The part is connected to the main body. When the flexible blocking piece is bent into the hanging notch, the flexible blocking piece abuts against the first abutting arc surface and occurs along the first abutting arc surface. Deformation, when the flexible blocking piece is bent out of the hanging notch, the flexible blocking piece abuts the second abutting arc surface and deforms along the second abutting arc surface, compared to At the beginning of the second arc surface, the beginning of the first arc surface is closer to the base of the blocking piece.

In one embodiment, in a free extension state, in a vertical direction, the height of the free end of the blocking piece is lower than or equal to the height of the hook end.

In one embodiment, the body member includes a body member through hole, a body member abutting portion, and a body member fitting portion, the body member abutting portion is located in the body member through hole, and the body member is fitted into the body member. The part is located in the through hole of the main body part, the flexible blocking piece passes through the through hole of the main body part, the flexible blocking piece further comprises a blocking piece inserting part, the base part of the blocking piece abuts against the main body part part, the blocking piece fitting part is fitted with the main body fitting fitting part.

In one embodiment, the main body further includes an abutting plane, the abutting plane is connected to the second abutting arc surface, one side of the abutting plane abuts the blocking plate base, and the first abutting arc surface One side abuts the base of the blocking piece, the first abutting arc surface, the second abutting arc surface and the abutting plane are located on the inner wall of the through hole of the main body, when the flexible blocking piece faces the hanging When bending occurs in the hanging notch, the flexible blocking piece abuts against the first abutting arc surface and deforms along the first abutting arc surface, and when the flexible blocking piece moves out of the hanging notch When bending, the flexible blocking piece abuts the The second abutting arc surface and the abutting plane, a part of the hook is deformed along the second abutting arc surface.

Applying the hook structure of the embodiment of the present invention, when the flexible blocking piece is bent into the hanging notch, the second segment is bent and deformed, and the main deformation stress is concentrated in the second flexible block. However, when the flexible baffle is bent out of the hanging notch, only the first segment is bent and deformed, and the main deformation stress is concentrated on the first bendable portion. Therefore, compared with the design of the conventional baffle plate that is repeatedly bent up and down at a single position, the flexible baffle plate of the embodiment of the present invention provides a deformation amount for the up and down bending at different positions (the first bendable portion provides the upward bending The second bendable portion provides the deformation amount of downward bending), so the lifespan of the flexible baffle can be extended indeed.
