[0025] The outer layer 2, the wear-resistant layer one 3 and the wear-resistant layer two 5 are all knitted by polyamide fiber strands and aramid fiber strands, the polyamide fiber strands and the aramid fiber strands are twisted and then weaved to form a connection, the combination of the two has the advantages of both, the aramid fiber strands have the self-extinguishing property of aramid fibers, which is extremely difficult to burn in a fire, so that the outer layer 2, the wear-resistant layer one 3 and the wear-resistant layer two 5 are both high wear-resistant and have the function of fireproofing, can withstand repeated friction and have a long service life.

[0026] As shown in Figures 1-4 The connecting piece includes a plurality of fixed pieces 6 rotatably connected to the top of the wear-resistant layer one 3, the fixed pieces 6 are provided with four pieces and have an arc, the four fixed pieces 6 can form a cylindrical shape that is attached to the surface of the outer layer 2, the top of the wear-resistant layer one 3 is provided with a through hole, the bottom of the fixed piece 6 is inserted into the through hole, so that the fixed piece 6 and the wear-resistant layer one 3 can rotate relative to each other, the side away from the wear-resistant layer one 3 of the two adjacent fixed pieces 6 is respectively slidably connected with an arc-shaped block one 7 and an arc-shaped block two 8, the arc-shaped block one 7 is slidably connected in the arc-shaped block two 8, the two adjacent arc-shaped block one 7 is connected by a spring 9, the diameter of the figure surrounded by the plurality of arc-shaped block two 8 is equal to the diameter of the outer layer 2, a through slot is formed in the center of the arc-shaped block two 8, and the arc-shaped block one 7 slides in the through slot. When the spring 9 is not subjected to external force, the fixed piece 6 abuts against the outer layer 2.

[0027] When the wear-resistant layer one 3 needs to be moved, the top of the fixed piece 6 can be pulled to make the four fixed pieces 6 open, and the spring 9 is stretched, so that the fixed piece 6 can be removed from the wear-resistant layer one 3, and the wear-resistant layer one 3 can be freely slid to the appropriate position, then the fixed piece 6 is released, the spring 9 returns to its original state, and the fixed piece 6 clamps the outer piece again, so that the wear-resistant layer one 3 is fixed at the current position.

[0028] As shown in Figures 1-4 The outer surface of the outer layer 2 is slidably connected with a support piece 10, the support piece 10 is arranged at the top of the arc-shaped block two 8, and the support piece 10 is slidably connected between the arc-shaped block two 8 and the outer layer 2.

[0032] In the case of fire or other situations that need to escape from a high place, the safety rope body is usually used in cooperation with other rescue facilities. When the safety rope body is used, the locking buckle at the top end of the safety rope body can be buckled on the roof or a place in the room that can support the weight of people, or the safety rope body can be directly bound to these places. Then the bottom of the safety rope body is directly thrown from the window or the railing. At this time, the safety rope body and the window or the railing form a corner. At this time, the supporting sheet 10 can be moved to insert the supporting sheet 10 between the arc-shaped block two 8 and the outer layer 2, and the arc-shaped block two 8 is separated from the top of the fixed sheet 6 and the arc-shaped block two 8. The spring 9 in the arc-shaped block two 8 deforms, so that the wear-resistant layer one 3 can slide outside the outer layer 2. When sliding to the corner, the user can hold the wear-resistant layer one 3 with one hand and move the supporting sheet 10 with the other hand, so that the spring 9 in the arc-shaped block two 8 restores to its original state, and the arc-shaped block two 8 is tightly attached to the outer layer 2. At this time, the fixed sheet 6 can clamp the outer layer 2, so that the wear-resistant layer one 3 can stay at the corner, preventing the safety rope body from directly rubbing against the corner when the safety rope body is used.
