[0022] As Figures 1 to 9 shown, the present invention discloses an anti-switching buckle. The technical solution adopted is to include a mounting plate 3. The interior of the mounting plate 3 is respectively provided with an NFC tag chip 6 and an embedded clamping block 4. Above the mounting plate 3, a long buckling plate 2 for protecting the NFC tag chip 6 is installed. Above the mounting plate 3, a short buckling plate 1 for protecting the embedded clamping block 4 is also installed. One end of the side wall of the embedded clamping block 4 is respectively provided with a through slot 12 and a blind slot 11. A sleeve 10 is rotatably installed inside the through slot 12. The inner side wall of the sleeve 10 is provided with an internal thread 14. A one-way mechanism is arranged inside the through slot 12 and the one-way mechanism is installed in cooperation with the sleeve 10. A flexible rod 5 is arranged inside the blind slot 11. The flexible rod 5 is installed in an insertion fit with the sleeve 10. By inserting one end of the flexible rod 5 into the inside of the sleeve 10, the flexible rod 5 drives the sleeve 10 to rotate inside the through slot 12 through the cooperation with the internal thread 14. At the same time, the rotation of the sleeve 10 is restricted by the one-way mechanism, thereby preventing the sleeve 10 from reversing, and further preventing the flexible rod 5 from withdrawing from the sleeve 10.

[0023] As a preferred technical solution of the present utility model, the single-row mechanism includes a ratchet ring 13, a rotating hook plate 15, a traction rod 16, and a traction spring 17. The ratchet ring 13 is fixedly installed outside the sleeve 10. The rotating hook plate 15 is rotatably installed inside the through groove 12 and is cooperatively engaged with the ratchet ring 13. Traction rods 16 are symmetrically arranged on the side wall of the rotating hook plate 15. The traction rods 16 are fixedly connected to the top end of the inner side wall of the through groove 12 through the traction spring 17. By rotating the sleeve 10, the ratchet ring 13 fixedly installed outside the sleeve 10 rotates. Furthermore, the ratchet ring 13 drives the rotatably installed rotating hook plate 15 to move downward, and the rotating hook plate 15 is pulled back through the traction rod 16 and the traction spring 17, so that the rotating hook plate 15 engages with the next tooth groove of the ratchet ring 13, thereby preventing the sleeve 10 from reversing.

[0024] As a preferred technical solution of the present utility model, the short buckling plate 1 and the long buckling plate 2 are integrally formed.

[0025] As a preferred technical solution of the present utility model, inner clamping grooves 8 are respectively formed at the bottom ends of the inner side walls of the short buckling plate 1 and the long buckling plate 2.

Through the clamping connection between the inner clamping groove 8 and the outer clamping groove 7, the integrally formed short buckling plate 1 and long buckling plate 2 can be clamped and installed on the surface of the mounting plate 3.

[0026] As a preferred technical solution of the present utility model, an external thread 9 that is threadedly installed in cooperation with the internal thread 14 is arranged on the outer side wall of the flexible rod 5. The flexible rod 5 is inserted and screwed with the sleeve 10 through the threaded connection between the external thread 9 and the internal thread 14. By inserting the flexible rod 5 into the sleeve 10 until the external thread 9 contacts the internal thread 14, and then continuously pushing the flexible rod 5 into the sleeve 10, the sleeve 10 rotates inside the through groove 12 through the screwed connection between the internal thread 14 and the external thread 9, so that the flexible rod 5 continuously inserts into the sleeve 10 and extends outside the sleeve 10.

[0027] Working principle of the utility model: By inserting the flexible rod 5 into the interior of the sleeve 10 until the external thread 9 contacts the internal thread 14, and then continuously pushing the flexible rod 5 into the interior of the sleeve 10, the sleeve 10 rotates inside the through groove 12 through the screwing of the internal thread 14 and the external thread 9, so that the flexible rod 5 continuously inserts into the interior of the sleeve 10 and extends to the outside of the sleeve 10. At the same time, through the rotation of the sleeve 10, the ratchet ring 13 fixedly installed outside the sleeve 10 rotates. Furthermore, the ratchet ring 13 drives the rotation hook plate 15 engaged and installed thereon to move downward, and through the traction rod 16 and the traction spring 17, the rotation hook plate 15 is pulled back, so that the rotation hook plate 15 engages with the next tooth groove of the ratchet ring 13, thereby preventing the sleeve 10 from reversing, and further preventing the flexible rod 5 from withdrawing from the sleeve 10.
