[0036] Please refer to Figure 2 , Figure 5 and Figure 6, the rotating assembly 130 includes a knob 132 and a rotating column 133, the knob 132 and the rotating column 133 are respectively arranged on the outer side and the inner side of the first buckle shell 110, the knob 132 is fixedly connected with the rotating column 133, the gear part 131 is arranged on the rotating column 133, the side wall of the rotating column 133 is provided with a recessed part 134, the first buckle shell 110 is internally provided with an elastic limiting assembly 160 corresponding to the recessed part 134, and the elastic limiting assembly 160 is used for being clamped with the recessed part 134 when the recessed part 134 moves to the position of the elastic limiting assembly 160 to realize limiting. Specifically, the rotating assembly 130 is composed of the knob 132, the rotating column 133 and the gear part 131, the knob 132 is located on the outer side of the first buckle shell 110, the rotating column 133 is arranged on the inner side, and they are coupled through fixed connection. The gear part 131 is installed on the rotating column 133, so that when a user rotates the knob 132, the rotating action of the knob 132 can drive the gear part 131 to rotate through the rotating column 133, so as to drive the fork assembly 120 to slide. The side wall of the rotating column 133 is provided with the recessed part 134, and the recessed part 134 cooperates with the elastic limiting assembly 160 in the first buckle shell 110. When the rotating column 133 rotates, the recessed part 134 moves along the circumference of the rotating column 133, and when reaching a certain specific position, the elastic limiting assembly 160 is clamped and fixed with the recessed part 134, so as to limit the further rotation of the rotating column 133. The limiting function can effectively ensure that the buckle can be accurately locked or unlocked, and the existence of the elastic limiting assembly 160 not only plays a physical limiting role, but also can provide a certain feedback force through elasticity, so that the user can perceive clear rotation resistance or 'clamping points' in the operation process, enhancing the operation feeling and improving the user experience.

The shape and size of the second limiting groove 233 are matched with the second limiting piece 240 to ensure that the second limiting clamping piece 231 can smoothly slide during clamping and disassembly.

[0043] During installation, the second limiting clamping piece 231 always tries to pop out under the elastic force of the third spring piece 232. When the second handle shell 210 is pushed into the installation slot, the second limiting clamping piece 231 is compressed, and the elastic force is temporarily stored. When the second limiting clamping piece 231 completely enters the installation slot, the elastic force of the third spring piece 232 makes it pop back to the original position and firmly clamps into the installation slot to achieve locking. During disassembly, press the second limiting clamping piece 231 to overcome the elastic force of the third spring piece 232, and it will be elastically deformed and come out of the installation slot.
