The tether ring 2 is located between the two fasteners 1 and can movably pass through the bottom wall 12 of the fastener 1 to push the fastener 1. The tether ring 2 can be partially placed inside the fastener 1, and one end or both ends move toward the opening 11 of the fastener 1 to complete the tethering action at the opening 11 end of the fastener 1.

[0032] Among them, one end of the fastener 1 is an opening 11 and has a hollow inner cavity, the opening 11 end is connected with the hollow inner cavity, and the tethering action can be completed at the opening 11 end, and the tethering ring 2 movably passes through the bottom wall 12 of the fastener 1, and is partially placed inside the fastener 1 and partially placed outside the fastener 1. The tethering rings 2 inside and outside the fastener 1 can be adjusted according to actual usage. The tethering ring 2 placed inside the fastener 1 can be tied, specifically, the end of the rope 4 freely passes through the tethering ring 2, and then moves in the direction of the main body of the rope 4, that is, the end of the rope 4 is folded in half, and the tethering ring 2 can achieve the purpose of pulling the end of the rope 4.

[0033] It should be noted that the fastener 1 of the present invention is test tube-shaped, and its inner diameter is smaller than the sum of the outer diameters of the two ropes 4, so as to prevent the ends of the ropes 4 from sliding back and forth. For example, the inner diameter of the fastener 1 is 0.8 cm, and the outer diameter of the rope 4 is 0.5 cm.

[0034] In addition to achieving the purpose of fastening by the above method, elastic and stretchable materials can be evenly arranged on the inner wall of the fastener 1. The elastic and stretchable materials can undergo elastic deformation according to whether it contains one rope 4 or two ropes 4. When the ends of the ropes 4 are folded in half, there are two ropes 4 in the fastener 1, and the elastic and stretchable materials are squeezed, which can also prevent the two ropes 4 from sliding back and forth.

[0035] In order to be able to adjust the distance between the ends of the two ropes 4 and adjust the length of the wound rope 4 within a certain range, an elastic telescopic member 3 is also included. The elastic telescopic member 3 is located between the two fasteners 1, and both ends are fixedly connected to the two fasteners 1 at the same time. The fixed connection of the present invention can be welding or other fixed connection methods, all of which are within the protection scope of the present invention.

The fastener 1 slides back and forth to drive the elastic telescopic member 3 to expand and contract. Figure 2 and Figure 3 As shown, the two fasteners 1 are close to each other, the elastic telescopic member 3 is in a compressed state, and one end of the tether ring 2 extends to the opening 11 of the fastener 1, which is convenient for tying and untying the rope.

[0037] In this embodiment, the bottom wall 12 of the fastener 1 is provided with a through hole 13 for the tether ring 2 to pass through. The tether ring 2 is a closed U-shaped ring, including a rod portion 21 and an arc portion 22. The rod portion 21 and the arc portion 22 are alternately arranged.

At the same time, the rod and arc surfaces of the steel bars or steel wire ropes exposed at the open end of the fastener are smooth, thereby preventing the rope from being cut when it is frequently passed.

[0040] In order to prevent the rope 4 from being cut due to frequent movement when entering, the inner wall of the bottom wall 12 of the fastener 1 is set to a smooth concave surface, that is, the inner bottom surface of the fastener 1 is smooth, and the opening 11 end of the fastener 1 should also be a smooth surface to reduce the friction between the rope 4.

[0041] The elastic telescopic member 3 of this embodiment is preferably a compression spring. For example, the length of the compression spring before compression is 11 cm (1.5 times of the closed U-shaped ring), and the length after compression is 1.5 cm. The total number of turns of the compression spring is preferably ten turns, but is not limited to ten turns. In addition, it is not limited to compression springs, and can also be other types of elastic members.
