A limit copper sleeve 21 is embedded in the end of the second straight cylinder 23.

[0023] It should be noted that the first straight cylinder 13 and the second arc cylinder 24, and the first arc cylinder 14 and the second straight cylinder 23 are mutually clamped, so that the first buckle body 100 and the second buckle body 200 form a snap buckle. Through the mutual cooperation of the rotary telescopic assembly 11 and the limit copper sleeve 21, the first arc cylinder 14 and the second straight cylinder 23 are rotatably and telescopically connected. A buckling opening is formed between the clamping post 22 and the rubber plug 12 to achieve the buckling or opening function.

[0024] For the purpose of reducing the volume of the present application, in some alternative embodiments, a rubber plug placement groove 131 is provided at the end of the first straight cylinder 13, and the rubber plug 12 is embedded at the rubber plug placement groove 131. Wherein, when the end face of the first straight cylinder 13 is in contact with the end face of the second arc cylinder 24, the clamping post 22 is embedded inside the rubber plug 12. When the end face of the first straight cylinder 13 is separated from the end face of the second arc cylinder 24, the clamping post 22 protrudes out of the outside of the rubber plug 12.

[0025] It should be noted that the rubber plug 12 is embedded in the rubber plug placement groove 131, which can reduce the overall volume of the first buckle body 100 and the second buckle body 200 and is convenient for carrying.

[0026] In order to make the buckling of the present application more stable, in some alternative embodiments, a convex ring 221 is provided on the clamping post 22, and a clamping groove 121 adapted to the convex ring 221 is provided on the rubber plug 12. Wherein, when the end face of the first straight cylinder 13 is in contact with the end face of the second arc cylinder 24, the convex ring 221 is embedded inside the clamping groove 121. When the end face of the first straight cylinder 13 is separated from the end face of the second arc cylinder 24, the convex ring 221 protrudes out of the outside of the clamping groove 121.

[0027] It should be noted that the provision of the convex ring 221 on the clamping post 22 and the provision of the clamping groove 121 on the rubber plug 12 make the buckling of the first straight cylinder 13 and the second arc cylinder 24 more stable.

[0028] In order to implement the function of rotational stretching adjustment of the present application, in some alternative embodiments, a rotational telescopic component activity groove 231 for the activity of the rotational telescopic component 11 is provided at the end of the second straight cylinder 23.

[0030] It should be noted that when it is necessary to open the fastening opening formed between the clamping post 22 and the rubber plug 12, the user stretches the first buckle body 100 and the second buckle body 200. Since the limit copper sleeve 21 is fastened in the rotational telescopic component activity groove 231, it abuts against the return spring 112, compressing the return spring 112. At the same time, the limit screw rod 111 is pulled outwards from the rotational telescopic component activity groove 231, and then the fastening opening is opened. By rotating the first buckle body 100 or the second buckle body 200, the area of the fastening opening is increased; when the object to be fastened enters the fastening area, rotate the first buckle body 100 or the second buckle body 200, and release the first buckle body 100 or the second buckle body 200. Since the return spring 112 rebounds due to the loss of tensile force, the limit screw rod 111 is reset, and then the fastening opening is closed.

[0031] In order to fix the limit screw rod 111, in some alternative embodiments, a limit screw rod placement groove 141 is provided at the end of the first arc column 14. Internal threads are provided on the inner wall of the limit screw rod placement groove 141. The screw rod end of the limit screw rod 111 is fixed to the internal threads of the limit screw rod placement groove 141 by external threads, so that the limit screw rod 111 is fastened to the end of the first arc column 14.
