After the screw rod 42 is penetrated into the first through hole and the second through hole, the rope body 43 firstly approaches the screw rod 42 from the outside of the conical sleeve 1, then the rope body 43 sequentially penetrates through the first through hole and the second through hole, the rope body 43 penetrating through the second through hole extends to one wire through hole 411 in the direction deviating from the screw rod 42, the rope body 43 penetrating through one wire through hole 411 winds to the other wire through hole 411 from the outer side of the rod-shaped nut 41 and penetrates through the other wire through hole 411, the rope body 43 penetrating through the other wire through hole 411 extends to the second through hole in the direction approaching the screw rod 42 and penetrates through the second through hole, the rope body 43 penetrating through the second through hole penetrates through the first through hole again, and the rope body 43 penetrating through the first through hole reaches the outside of the conical sleeve 1 and extends in the direction deviating from the screw rod 42. In this way, in the process of pulling the two ends of the rope body 43, since the rope body 43 passing through the two wire passing holes 411 enters the second through hole in the direction approaching to the screw rod 42, the rope body 43 will tighten the rod nut 41 in the direction of the screw rod 42, so as to avoid the rod nut 41 from being separated from the screw rod 42; since both ends of the rope body 43 are opened in a direction away from the screw rod 42, the rope body 43 is not easy to interfere with the movement of the screw rod 42 during the traction process.
In one embodiment, the two adjacent conical sleeves 1 are respectively provided with a cross mark, so that the two adjacent conical sleeves 1 can be spliced and aligned when being sheathed with each other.
