The size of the bayonet 23 in the circumferential direction of the bayonet hole 21 is smaller than the diameter of the second tail end 12. In this embodiment, the size of the narrow end of the bayonet 23 in the circumferential direction of the card hole is smaller than the diameter of the second tail end 12, and the second tail end 12 is not easy to be separated from the narrow end of the bayonet 23, which is beneficial to limiting the second tail end 12 in the card hole 21.

The fixing hole 22 and the clamping hole 21 are both cylindrical, the cross section of the fixing hole 22 is circular, the cross section of the clamping hole 21 is O-shaped, the fixing hole 22 is located in the long axis direction of the clamping hole 21, and the end portion, far away from the fixing hole 22, of the clamping hole 21 in the long axis direction is communicated with the bayonet 23. The first tail end 11 is more attached to the inner wall of the fixing hole 22, and the connection between the first tail end and the fixing hole is more stable. Second end 12 is compressed and compressed as it passes through bayonet 23, and "O" -shaped clip aperture 21 is further adapted to receive compressed second end 12.

In other embodiments, the cross section of the card hole can be round, so that the preparation is convenient.

The first tail end 11 is in interference fit with the fixing hole 22; the second end 12 is interference fit with the snap hole 21. First tail end 11 is more stable with being connected of fixed orifices 22, and second tail end 12 is more stable with being connected of card hole 21, avoids buckle 2 unexpected slip on stay cord 1, promotes the use and feels.

In other embodiments, the second tail end and the clamping hole can be in transition fit, so that the second tail end and the clamping buckle can be conveniently disassembled and assembled.

Or, the first tail end 11 and the fixing hole 22 may be in transition fit, so that the buckle 2 can slide on the pull rope 1 conveniently, and different positions of the buckle 2 on the pull rope 1 can be set conveniently.

The side wall of the clip 2 provided with the bayonet 23 is planar parallel to the axial direction of the clip hole 21. The bayonet 23 is the plane with the face of lateral wall intercommunication to this plane is on a parallel with card hole 21 axial, is convenient for remove second tail end 12 to card hole 21 department from the outside, has increased the thickness that bayonet 23 kept away from 2 one ends of buckle, has improved structural strength.

In other embodiments, the side wall of the buckle provided with the bayonet can be arranged into a semi-cylindrical shape coinciding with the central axis of the clamping hole, and the clamping hole is arranged along the cambered surface of the side wall, so that the clamping hole is convenient to arrange.

The side wall of the clip 2 opposite to the side wall near the fixing hole 22 is semi-cylindrical, and the axial direction of the side wall is parallel to the axial direction of the fixing hole 22. When the second tail end 12 is inserted into the fastening hole 21, the finger needs to press the sidewall of the fastening hole 22, which is beneficial to improving the comfort of pressing. The fixing hole 22 can be arranged along the arc surface of the side wall, and the central axis of the fixing hole 22 coincides with the central axis of the side wall, so that the fixing hole 22 can be conveniently arranged on the buckle 2.
