Referring to fig. 3, 4, 5, 6, 7, which are a front view of the female buckle, a schematic view before the male buckle is pushed into the female buckle, a schematic view after the male buckle is pushed into the female buckle, a cross-sectional view before the male buckle is pushed into the female buckle, and a cross-sectional view after the male buckle is pushed into the female buckle, the overall assembly process of the present invention is to push the hook 2113 at the suspended end of the elastic arm 2112 of the elastic body 211 to the guiding slope 1111 of the buckling part 111 at the two sides of the base 11 of the female buckle 1 by using the abutting part 21 of the male buckle 2 to push the opening of the inserting space 120 of the female buckle 1, and make the two elastic bodies 211 present an elastic deformation state toward the guiding rod 212, when the hook 2113 passes the guiding slope 1111 and enters the buckling groove 1112, the elastic body 211 returns to the original state to form a buckling position, at this time, the gap above the central guiding rod 212 of the abutting part 21 of the male buckle 2 slides into the positioning groove 214 formed between the guiding rod 212 and the stopper 213 along the two convex rails 1221, the bottom of the guiding rod 212 slides into the rail 1212 along the guiding groove 1211 of the bottom plate 121 of the female buckle 1 to be positioned, so that the integral assembly of the female buckle 1 and the male buckle 2 is completed.

However, after the assembly of the female buckle 1 and the male buckle 2 is completed, the whole pressing surface 2111 of the elastic body 211 of the male buckle 2 is located at the notch formed by the turning surface 112 of the base 11 of the female buckle 1, the side of the bottom plate 121 and the outer side of the top plate 122, which is slightly below the top plate 122, the top plate 122 is located above the pressing surface 2111 and the step surface 201 of the body 20, and the outer side of the female buckle 1 and the outer side of the pressing surface 2111 of the male buckle 2 form a substantially same plane, so that the female buckle 1 and the male buckle 2 are combined to present a flat and simple appearance and have the effect of not hooking clothes or other foreign matters easily.

Moreover, in the process of pushing the male buckle 2 into the female buckle 1, the upper and lower surfaces of the central guiding rod 212 of the abutting portion 21 can be guided and positioned along the gap between the two protruding rails 1221 of the top plate 122 of the female buckle 1 and the guiding groove 1211 and the rail 1212 of the bottom plate 121, so that the male buckle 2 can be easily pushed into the inserting space 120 of the female buckle 1 to be positioned and is not easy to shake for use.

When the abutting portion 21 of the male buckle 2 is going to be withdrawn from the inserting space 120 of the female buckle 1, the user can press the pressing surface 2111 on the outer side of the two sides of the elastic body 211 of the male buckle 2, at this time, the two elastic bodies 211 are elastically deformed toward the direction of the guiding rod 212, so that the two buckle hooks 2113 are separated from the buckling groove 1112, and the abutting portion 21 of the male buckle 2 can be pulled out from the inserting space 120 of the female buckle 1, so that the male buckle 2 can be separated from the female buckle 1.

Furthermore, a gap slightly larger than the distance of the hook 2113 separating from the fastening groove 1112 is formed between the inner side surface of the pressing surface 2111 of the elastic body 211 and the outer side surface of the base plate 121, and the pressing surface 2111 of the elastic body 211 can also form a limit structure design of elastic deformation during pressing operation, so as to achieve the purposes of beautiful appearance, firm fastening and difficult damage.

In addition, in the present invention, since the two pressing surfaces 2111 are bent inward at the center of the inner side and then extended forward with an elastic arm 2112 and the end of the elastic arm 2112 is bent outward to form a hook 2113 structure, when the user presses the outer pressing surface 2111 on both sides of the elastic body 211 of the male buckle 2, the force application position of the two pressing surfaces 2111 is the extending position of the elastic arm 2112, and the pressing surface 2111 of the elastic body 211 forms a limit structure design of elastic deformation during pressing operation, so as to achieve the purpose of hard damage.

The thickness of the guiding rod 212 of the butt-joint portion 21 of the male buckle 2 is larger than that of the elastic body 211 and the stopper 213, when the male buckle 2 is pushed into the insertion space 120 of the female buckle 1, the elastic body 211 can perform large elastic deformation, and the hook 2113 can perform smooth pushing movement, thereby forming the pushing characteristic with low insertion force.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
