The other end of the elastic hook passes through the first limiting hole from the rear side of the main body and abuts against the front side of the main body. A hook connection is formed between the two ends of the elastic hook, which can be rotatably inserted into or removed from the limiting slot.

2. The G-shaped fastener according to claim 1, wherein The elastic hook includes a first horizontal portion, a first vertical portion and a second vertical portion fixed at both ends of the first horizontal portion and arranged in parallel, a first inclined portion fixedly connected to the bottom end of the first vertical portion and extending obliquely, a second horizontal portion fixed to the bottom end of the first inclined portion and extending towards the second vertical portion and parallel to the first horizontal portion, a first locking portion fixed to the end of the second horizontal portion and extending away from the first horizontal portion, a second inclined portion fixedly connected to the bottom end of the second vertical portion and extending obliquely, a third horizontal portion fixed to the bottom end of the second inclined portion and extending towards the first vertical portion and parallel to the first horizontal portion, and a second locking portion fixed to the end of the third horizontal portion and extending away from the first horizontal portion; the first horizontal portion, the first vertical portion, and the second vertical portion together form the hook portion; The first inclined portion and the second inclined portion are inclined to the same side of the first horizontal portion. The second horizontal portion is located above the third horizontal portion. The second horizontal portion passes through the first limiting hole so that the first snap-fit ​​portion is limited and abutted against the front side of the main body portion. The third horizontal portion passes through the second limiting hole so that the second snap-fit ​​portion is limited and abutted against the rear side of the main body portion.

3. The G-shaped, inside opening fastener according to claim 2, wherein The angle between the first inclined portion and the first vertical portion is an obtuse angle, the angle between the second inclined portion and the second vertical portion is an obtuse angle, and the angle between the second inclined portion and the second vertical portion is greater than the angle between the first inclined portion and the first vertical portion.

4. The G-shaped, female fastener of claim 2, wherein The first snap-fit ​​portion is parallel to the first vertical portion, and the angle between the second snap-fit ​​portion and the second inclined portion is an obtuse angle.

5. The G-shaped, inside opening fastener according to claim 4, wherein The first limiting hole is a strip-shaped hole extending along the width direction of the main body. The first snap-fit ​​part is limited and abutted against the lower opening edge of the strip-shaped hole. A through hole penetrating the front and rear sides of the main body is provided below the first limiting hole. A stop block is provided in the through hole and is fixedly connected to the bottom wall of the through hole and the inner wall of the through hole facing away from the middle of the main body. The stop block divides the space inside the through hole to form a second limiting hole with an inverted L-shaped structure. The second snap-fit ​​part is limited and abutted against the rear side of the stop block.

6. The G-shaped fastener according to claim 5, wherein The front and rear sides of the main body are provided with fan-shaped grooves located below and communicating with the first limiting hole. The inner side of the fan-shaped grooves is in limiting contact with the first snap-fit ​​part. The thickness of the stop block is less than the thickness of the main body.

7. The G-shaped fastener according to claim 5, wherein The front side of the block is a guide slope, and the rear side of the block is a vertical plane perpendicular to the thickness direction of the block. The thickness of the block gradually decreases along the direction close to the middle of the main body.

8. The G-shaped fastener according to claim 1, wherein The inner side of the limiting slot adjacent to the main body is provided with a U-shaped through groove that communicates with the limiting slot. The U-shaped through groove passes through the front and rear sides of the cantilever.

9. The G-shaped fastener according to claim 1, wherein The upper surface of the main body is provided with a first inclined surface at the corresponding second mounting part. The height of the region adjacent to the middle of the main body on the first inclined surface is higher than the height of the region away from the middle of the main body on the first inclined surface. The cantilever is provided with a second inclined surface corresponding to the first inclined surface below the limiting slot. The shape of the first inclined surface is adapted to the shape of the second inclined surface.

10. The G-shaped fastener according to claim 1, wherein The main body has a U-shaped structure, and a first crossbar is fixed between the two vertical arms of the main body. The first crossbar and / or the crossbar of the main body form the connecting part; or a second crossbar and a third crossbar located above the second crossbar are fixed between the two vertical arms of the main body. The upper surface of the crossbar of the main body is a concave arc surface. The second crossbar is located on the front side of the concave arc surface, and the third crossbar is located above the concave arc surface. The second crossbar forms the connecting part.
