The clamping and fixing of the positioning portion are achieved through the arrangement, and the left position and the right position of the buckle are fixed.
Preferably, the fixed shaft is sleeved with a cushion block, and the cushion block is limited between the buckle and the front part. The cushion block is arranged for reducing the contact area between the side face of the buckle and the side face of the front part, so that the rotation of the buckle is facilitated.
Preferably, the front part extends backwards to form an extension part positioned at the side of the front end of the rear part, and the buckle assembly is positioned on the extension part; or the rear part extends forwards to form an extension part which is positioned at the side of the rear end of the front part, and the positioning shaft is positioned on the extension part. Through setting up the extension to make buckle subassembly can be farther from the articulated shaft, so that the fixed effect of location between preceding part and the back part is better.
The invention has the advantage that the position of the buckle can be adjusted, so that the buckle can be clamped on the positioning shaft.
