The wire clamp is used to clamp the Dyneema rope body, and the end of the wire clamp is connected to the ground anchor through a U-shaped ring. This method requires the use of a special wire clamp, which will damage the clamping part of the Dyneema rope, and the reliability of long-term use is not high; and a rope loop is tied in the middle of the Dyneema rope with a rope loop, the rope loop is directly connected to the ground anchor, and the excess Dyneema rope is turned 180 degrees and fixed to the original Dyneema rope through a U-shaped clamp. Due to the small contact area between the Dyneema rope and the U-shaped clamp, this method requires a large deformation of the Dyneema rope to ensure sufficient friction, which often causes damage to the Dyneema rope and affects its reliability for reuse.

[0039] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0040] like Figures 4 to 6 As shown, in an embodiment of the present invention, the locking structure 14 includes an external static pressure head 143 and an internal dynamic pressure head 144, the external static pressure head 143 is fixedly connected to one end of the winding structure 12, the external static pressure head 143 has a through groove 145 for accommodating the internal dynamic pressure head 144, the minimum diameter of the through groove 145 is equal to the diameter of the rope, the internal dynamic pressure head 144 is arranged in the through groove 145 of the external static pressure head 143, the internal dynamic pressure head 144 is provided with a through hole 142, the minimum diameter of the through hole 142 is equal to the diameter of the rope.

[0041] In this embodiment, the locking structure 14 includes an external static pressure head 143 and an internal dynamic pressure head 144. The external static pressure head 143 is fixedly connected to one end of the winding structure 12, thereby realizing the fixed connection between the locking structure 14 and the winding structure 12. The external static pressure head 143 has a through groove 145 for accommodating the internal dynamic pressure head 144. The through groove 145 penetrates the external static pressure head 143 along the length direction of the external static pressure head 143. The internal dynamic pressure head 144 is arranged in the through groove 145 of the external static pressure head 143. The minimum diameter of the through groove 145 is equal to the diameter of the rope, and the internal dynamic pressure head 144 is adapted to the accommodating groove of the external static pressure head 143, so that the external static pressure head 143 and the internal dynamic pressure head 144 squeeze each other to generate static friction, thereby constraining the movement of the rope end in the through hole 142 arranged in the internal dynamic pressure head 144, thereby further completing the locking operation of the rope.

The shape of the internal dynamic pressure head 144 is adapted to the external static pressure head 143, so that the static friction force generated by the mutual squeezing of the truncated cone-shaped internal dynamic pressure head 144 and the external static pressure head 143 can constrain the movement of the rope, thereby fixing the end of the rope.

[0047] Optionally, the internal dynamic pressure head 144 is disposed inside the external static pressure head 143 , and the top end of the internal dynamic pressure head 144 is at a preset distance from the top end of the external static pressure head 143 .
