[0002] A buckle is a connecting tool used on items such as clothing and bags, capable of being connected or disconnected. Prior art (Announcement No. CN101721017B, Announcement Date: October 3, 2012) discloses a buckle with a whistle attached. The whistle is detachably connected to the buckle body, making it convenient for practical use. However, traditional buckles are generally made of plastic and include a plug and a socket. The plug is snapped into the socket using elastic arms on either side. This method requires injection molding of a plastic with a certain degree of elasticity. Due to the low strength of the plastic, the buckle has a short service life and is prone to breaking when subjected to strong pulling forces.

[0003] To this end, the prior art (Announcement No.: CN220832138U, Announcement Date: 2024.04.26) discloses an easy-to-fasten buckle, which fixes the strap on a sliding part. The sliding part can slide on the sub-buckle to clamp the strap and thereby fix the strap, making it easier for the user to pull the buckle with the strap.

[0004] However, the buckle of this solution cannot rotate 360°. When used in certain scenarios, a rotating part needs to be installed by riveting, which causes the buckle to occupy a large space and has a certain impact on the strength of the entire buckle. Utility Model Content

[0032] like Figure 1-5 As shown, a 360° rotating fastener of the present invention includes a female buckle 1 and a male buckle 2; the female buckle 1 is formed with a through slot 3, which is arranged to pass through the female buckle 1 horizontally, and a fastener 4 is installed in the through slot 3 with clearance fit; an insertion hole 5 is formed in the middle of the upper side of the female buckle 1, and the bottom end of the insertion hole 5 is connected to the through slot 3;

[0033] The middle part of the lower side of the sub-button 2 is rotatably mounted with a positioning shaft 6, and a buckle groove 7 is formed on the outer side of the lower end of the positioning shaft 6. The positioning shaft 6 is inserted into the through groove 3 through the insertion hole 5. A buckle position 8 is provided in the middle part of the upper side of the buckle 4. The bottom end of the positioning shaft 6 is inserted into the buckle position 8, and a snap connection is formed between the buckle position 8 and the buckle groove 7 of the positioning shaft 6;

[0034] The principle is: the positioning shaft 6 on the lower side of the sub-buckle 2 is directly inserted into the plug-in hole 5 of the mother buckle 1, and the fastener 4 will fasten the fastening groove 7 at the bottom end of the positioning shaft 6 through the fastening position 8 to achieve a stable fitting connection. The various parts of the mother buckle 1 and the sub-buckle 2 are all made of metal, so they are not easy to damage and can withstand greater pulling force. At the same time, the positioning shaft 6 is rotatably installed on the bottom side of the sub-buckle 2. Compared with the existing square plug buckle, the utility model can achieve 360° rotation without being equipped with a suitable rotating part, occupies a small space, is more convenient to use, and can ensure its service life.

Compared with traditional plastic buckles, this solution has higher strength, and metal parts generally will not corrode or age, thereby increasing the service life of the buckle.

[0036] Furthermore: the outer end of the clamping block 42 is formed with a pressing portion 421, and the pressing portions 421 of the two clamping blocks 42 are respectively installed at the left and right ends of the through groove 3 with a clearance fit, and the middle part of the clamping block 42 is formed with a side-inserted sliding block 422, and the side-inserted sliding blocks 422 of the two clamping blocks 42 are spliced with each other and installed in the through groove 3 with a clearance fit, and the inner end of the clamping block 42 is formed with an inverted block 423, and the inverted blocks 423 of the two clamping blocks 42 form a buckling position 8; when the pressing portions 421 on both sides are pressed, the inverted blocks 423 of the two clamping blocks 42 will separate from each other, thereby achieving the effect of opening the buckling position 8, so that the buckling position 8 no longer jams the buckling groove 8 of the positioning shaft 6, thereby realizing the rapid disassembly of the sub-buckle 2.

[0037] Furthermore, there are two elastic members 41 , which are mounted one-to-one in contact with the inner wall of the pressing portion 421 and the outer wall of the inverted block 423 , thereby ensuring that the two pressing portions 421 are quickly reset after being pressed, facilitating practical use.

[0038] Furthermore: the side-inserted sliding blocks 422 of the two clamping blocks 42 are both formed with oblong holes 4221, the front side of the female buckle 1 is formed with a socket 9, the rear end of the socket 9 is inserted into the through slot 3, and an insert rod 10 is installed in the socket 9, and the insert rod 10 is inserted into the oblong holes 4221 of the two clamping blocks 42 with a clearance fit; the cooperation between the insert rod 10 and the oblong hole 4221 can realize the stable sliding of the clamping block 42 in the through slot 3, so that the buckling position 8 can stably buckle the positioning shaft 6.

[0039] Furthermore: the elastic member 41 is a spring.

[0040] Furthermore, a spring groove 11 is formed on the inner side of the pressing portion 421 , the outer end of the elastic member 41 abuts against the spring groove 11 , and the inner end of the elastic member 41 abuts against the outer side of the undercut block 423 , making the installation of the elastic member 41 more stable.

[0041] Furthermore: a groove 12 is formed on the inner side of the pressing portion 421, and the groove 12 is arranged below the spring groove 11. A protrusion 13 is formed on the bottom end of the outer side of the inverted block 423, and the protrusion 13 is installed in the groove 12 with a one-to-one clearance fit; so that the overall sliding of the clamping block 42 is smoother and more stable.

[0042] Furthermore, both the female buckle 1 and the male buckle 2 are formed with strap holes 14, which can facilitate the connection of straps for use.

[0043] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model.
