[0001] This utility model relates to the field of button technology, and in particular to a manually installed metal snap fastener. Background Technology
[0002] Fasteners are widely used in daily life, appearing on clothing, shoes, hats, bags, backpacks, and tote bags. Snap fasteners are a type of fastener consisting of four parts: a female snap fastener face, a female snap, a male snap, and a male snap fastener face. The female snap and female snap fastener face are riveted together and clamped onto the fabric on one side, while the male snap fastener face and male snap fastener face are riveted together and clamped onto the fabric on the other side. Currently, during use, buttons often break due to insufficient and unstable fastening force between the female snap and female snap fastener face, or between the male snap and male snap fastener face. Damaged buttons are difficult to replace, and existing snap fasteners cannot be manually replaced, reducing their convenience. Therefore, it is necessary to improve the structure to overcome these shortcomings. Summary of the Invention
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a manually installed metal snap fastener.
[0004] The objective of this utility model is achieved through the following technical solution: A manually installed metal snap fastener includes a first snap face, a female snap, a second snap face, and a male snap. The first snap face has a first protrusion at its center, and the first snap face and the female snap are detachably connected through the first protrusion.

[0005] Furthermore, the female buckle is provided with a first elastic component that cooperates with the first protrusion, and the male buckle is provided with a second elastic component that cooperates with the second protrusion.
[0006] Furthermore, the male buckle is surrounded by several U-shaped slots, the free ends of which extend outwards respectively. In use, the mounting ends of the U-shaped slots abut against both sides of the second protrusion.
[0007] Furthermore, the first elastic component and the second elastic component are each composed of two spring pieces. The two spring pieces contact each other to form a conical spring piece. When the first protrusion and the second protrusion are inserted into the first elastic component and the second elastic component, the spring pieces that make up the first elastic component and the second elastic component expand outward and respectively lock the first protrusion and the second protrusion.
[0008] Furthermore, the surfaces of the first protrusion and the second protrusion are provided with concave and convex grooves, which abut against the first elastic component and the second elastic component provided on the male buckle and the female buckle.
[0009] Furthermore, the female buckle also includes a female buckle cavity, and a plurality of O-rings are arranged around the bottom of the female buckle cavity. When fastened, the O-rings abut against the outside of the U-shaped groove, and the O-rings provide a squeezing and fastening force to the male buckle and the first protrusion and the second protrusion of the female buckle.
[0010] Furthermore, the first and second buckle surfaces each include a button surface and a buckle base, the buckle base being fitted into the bottom of the buckle surface, and the buckle base material being zinc alloy.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By using a separate and detachable connection of the first buckle surface, the female buckle, the second buckle surface and the male buckle, the components are connected by snaps or fastenings.

[0018] Preferably, the male buckle 4 is surrounded by a U-shaped groove 7, the free ends of which extend outwards respectively. In use, the mounting ends of the U-shaped groove 7 abut against both sides of the second protrusion 6.
[0019] In this embodiment, a first protrusion 5 is provided in the first opening surface 1, and a groove corresponding to the first protrusion 5 is provided in the female buckle 3. The first protrusion 5 is inserted into the first elastic component to make the first buckle surface 1 and the female buckle 3 snap together. Similarly, a second protrusion 6 is provided in the second buckle surface 2, and a groove corresponding to the second protrusion 6 is provided in the male buckle 4. The second protrusion 6 is inserted into the second elastic component to make the second buckle surface 2 and the male buckle 4 snap together. Damaged buttons can be manually replaced, improving the convenience of button use. At the same time, damaged parts can be replaced individually, improving the replacement efficiency.
[0020] Preferably, the first elastic component and the second elastic component are each composed of two spring sheets, and the two spring sheets contact each other to form a conical spring sheet 8. When the first protrusion 5 and the second protrusion 6 are inserted into the first elastic component and the second elastic component, the spring sheets that make up the first elastic component and the second elastic component expand outward and lock the first protrusion 5 and the second protrusion 6.
