Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 8, the preferred embodiment of the single-opening buckle of the present invention includes a male buckle 1 and a female buckle 2 which are inserted into each other.

The male buckle 1 is provided with an insertion portion 3 to be inserted into the female buckle 2 and locked and engaged therewith. A first groove 4, a second groove 5, and a third groove 6 are provided on the front surface of the insertion portion 3, respectively. One end of the first groove 4 is located at the lower end of the insertion portion 3, and the other end thereof is turned to the left side of the insertion portion 3. The second recess 5 is located on the right side of the insertion portion 3. The third grooves 6 are juxtaposed on the side of the second grooves 5 and parallel to the second grooves 5.

The female buckle 2 comprises a female buckle shell 7 and a pressing piece 8 movably clamped with the female buckle shell 7. The pressing portion 81, the connecting portion 82, and the elastic portion 83 are integrally connected to the pressing piece 8. The pressing portion 81 is located at the left end of the pressing member 8, the elastic portion 83 is located at the right end of the pressing member 8, and the connecting portion 82 is connected to the pressing portion 81 and the elastic portion 83, respectively. The pressing portion 81 is attached to the left side of the box housing 7, and the connecting portion 82 and the elastic portion 83 are attached to the inside of the box housing 7.
