[0057] The buckle works like this:

[0058] When assembly is required, the first snap plate 21 and the second snap plate 22 are both installed on the base 243, wherein one end of the first snap plate 21 is located in the accommodating cavity 2451, and the other end is located outside the base 243 after passing through the first opening cavity 2452, and one end of the second snap plate 22 is located in the accommodating cavity 2451, and the other end is located outside the base 243 after passing through the second opening cavity 2453, and then two elastic members 23 are installed, one end of one elastic member 23 abuts against a protrusion 246 in the accommodating cavity 2451, and the other end abuts against the first snap plate 21, one end of the other elastic member 23 abuts against another protrusion 246 in the accommodating cavity 2451, and the other end abuts against the second snap plate 22, then the disassembly plate 10 is installed on the two support blocks 27 through the support shaft 26, the cover plate 244 is installed, and finally the disassembly plate 10 is rotatably connected to the supporting plate 32 in the buckle belt 30 through the pin shaft 40, and the assembly of the finished product is completed.

[0059] When snapping is required, the two elastic members 23 are in an extended state. The disassembly plate 10 and the snapping device 20 are rotated together, the card slot 25 is aligned with the card head 311 and the snapping device 20 is pressed down with force. At this time, the disassembly plate 10 is attached to the supporting plate 32, and the reinforcing arm 321 in the supporting plate 32 is located in the storage groove 11 of the disassembly plate 10. Under the elastic action of the two elastic members 23, the first snap plate 21 and the second snap plate 22 can be respectively inserted into the two positioning grooves 3111, so that the card head 311 is inserted into the card slot 25. At this time, the two elastic members 23 are in a slightly compressed state.

[0060] When it is necessary to unfold, by pressing the first snap plate 21 and the second snap plate 22 , the two elastic members 23 are in a compressed state, the first snap plate 21 and the second snap plate 22 are both detached from the clamping head 311 , and the clamping head 311 is detached from the clamping slot 25 .

[0061] In summary, the present invention has a watch buckle installed on the watch strap, wherein the buckle seat 24 is used to connect with the first strap body of the watch strap, and the buckle frame 31 is used to connect with the second strap body of the watch strap. When buckling is required, the two elastic members 23 are in an extended state, and the disassembly plate 10 and the buckling device 20 are rotated together, the disassembly plate 10 is attached to the supporting plate 32, and the clamping head 311 can be clamped in the clamping slot 25. At this time, the two elastic members 23 are in a slightly compressed state. When it is necessary to unfold, by pressing the first snap plate 21 and the second snap plate 22, the two elastic members 23 are compressed, the first snap plate 21 and the second snap plate 22 are both separated from the clamping head 311, and the clamping head 311 can be taken out of the clamping slot 25. The operation process is simple, it is convenient to wear the watch on the arm, and there is no need to open a clamping hole on the watch strap, which will not damage the watch strap, and is suitable for large-scale promotion.

[0062] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
