Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

As shown in fig. 1-8, a clip assembly includes a clip strip 1, two ends of the clip strip 1 are aligned and bent into a ring shape with an opening, the outer sides of the left and right ends of the clip strip 1 are respectively provided with a first buckle sleeve 2 and a second buckle sleeve 3, the clip strip 1 is provided with a fastening strip 4 passing through the first buckle sleeve 2 and the second buckle sleeve 3, two ends of the fastening strip 4 are outwards bent and provided with a tail buckle 5, a size positioning block 6 is arranged between the tail buckle 5 and the second buckle sleeve 3, and the clip strip 1 is provided with a buckle strip 7 adapted to the size positioning block 6; in a free state, the hoop strip 1 expands outwards for a certain distance under the action of elasticity of the hoop strip 1, two ends of the fastening strip 4 bend outwards for 90 degrees to form a tail warp 5, the middle of the fastening strip is shaped along the outer surface of the hoop strip 1, and the fastening strip 1 is tensioned under the action of the size positioning block 6; the lower surface of the size positioning block 6 is shaped along the outer surface of the fastening strip 4 and used for tightly pulling the clamp strip 1 under the coaction with the fastening strip 4, and the clamp component can obtain a plurality of different nominal diameters by changing the size positioning blocks 6 with different length sizes; the buckle strip 7 on the hoop strip 1 can be internally buckled by a clamp tool.

In this embodiment, the second buckle sleeve 3 is provided with a rectangular notch 8 adapted to the size positioning block 6; a rectangular notch 8 is punched at the right part of the second buckle sleeve 3 and is used for positioning when the size positioning block 6 is installed, and the size positioning block 6 is fixed together with the buckle strip 7.
