[0036] The specific buckle operation and mechanism of the application are as follows:

[0037] Locking buckle: when the head nail 101 is inserted into the hollow horizontal pipe 202, first, the head cap 103 at the front end of the head nail 101 is in contact with the front end of the gold nail 204, and the gold nail 204 is retreated backward against the elastic force of the spring 205. In order to facilitate the head cap 103 to retreat the gold nail 204, the cap head of the head cap 103 can be provided in a spherical cap structure or a rounded corner. The head nail 101 continues to advance until it slides onto the clamping groove component 102 and is in contact with the annular protrusion 1021. After the clamping groove component 102 is pushed to slide a small section on the head nail 101, the clamping groove component 102 is limited and fixed by the shaft shoulder between the front section and the rear section of the nail body of the head nail 101. At this time, the front end of the gold nail 204 is clamped in the first annular groove on the first annular body 1022 to achieve locking buckle, and the first buckle assembly 100 and the second buckle assembly 200 are fixedly connected.

[0038] Buckle opening: when the locked first buckle assembly 100 and the second buckle assembly 200 are separated, two steps are needed to complete. First, continue to push the head nail 101 in the direction of locking buckle, so that the gold nail 204 slides through the annular protrusion 1021 and falls into the second annular groove on the second annular body 1023. Then, pull the head nail 101 in the opposite direction. The gold nail 204 will first abut against the annular protrusion 1021 and drive the clamping groove component 102 to slide towards the head cap 103, and the first annular body 1022 is inserted into the annular accommodating cavity of the head cap 103 to narrow the opening of the first annular groove, until the clamping groove component 102 no longer moves. At this time, continue to pull the head nail 101, and the gold nail 204 will be pushed open by the annular protrusion 1021, and the head nail 101 will be pulled out of the hollow horizontal pipe 202 at the moment when the gold nail 204 does not fall into the first annular groove, so as to achieve buckle opening and separate the first buckle assembly 100 and the second buckle assembly 200.

[0039] In order to achieve better nail pulling, the outer diameter of the first annular groove is smaller than the outer diameter of the second annular groove. Further, the head cap 103 is provided with a beveled hole edge at the end close to the clamping groove component 102, which cooperates with the slope surface of the annular protrusion 1021, so that part of the annular protrusion 1021 can be hidden in the head cap 103 when the clamping groove component 102 slides towards the head cap 103. Therefore, when the gold nail passes the annular protrusion 1021 during nail pulling, it will not fall into the first annular groove, but will fall onto the head cap 103.

[0040] Although the specific embodiments of the present application are described above, those skilled in the art should understand that these are only examples, and various changes or modifications can be made to the embodiments without departing from the principles and essence of the present application, and the protection scope of the present application is only limited by the appended claims.
