Description

Technical Field

[0001] This utility model relates to the field of adjustment structure technology, and in particular to a swivel buckle and a combination of swivel buckles. Background Technology

[0002] like Figure 1 As shown, the adjustment buckle of the related technology includes an outer frame 1 and a crossbar 2 disposed inside the outer frame 1. A first adjustment band 3 is wrapped around the crossbar 2, and a second adjustment band 4 is fastened to the outer periphery of the crossbar 2. When the first adjustment band 3 and the second adjustment band 4 are adjusted relative to each other, the rotation of the second adjustment band 4 increases the resistance, causing the second adjustment band 4 to easily get stuck with the first adjustment band 1, making it impossible to adjust the length, and thus making the adjustment too cumbersome.

[0003] like Figure 2 As shown, the adjustment buckle of the related technology includes an outer frame 1 and two crossbars 2 disposed inside the outer frame 1. The first adjustment band 3 is wrapped around the first crossbar 2, and the second adjustment band 4 is fastened to the outer periphery of the second crossbar 2. When the first adjustment band 3 and the second adjustment band 4 are adjusted relative to each other, the rotation of the second adjustment band 4 increases the resistance, causing the second adjustment band 4 to easily get stuck with the first adjustment band 1, making it impossible to adjust the length. This makes the adjustment too cumbersome. Moreover, because the adjustment buckle needs to be set with two crossbars 2, its structure is relatively large, which is not conducive to the application of compact equipment. Utility Model Content
