[0025] like Figure 1 and Figure 3 Cables 1 are arranged at equal angles on the outside of the middle bracket 2, and the cable 1 is fitted with the bracket 2. The bracket 2 is made of rubber material to avoid friction of the cable 1. The wrapping belt 4 is a grid structure woven with mica wires, which is resistant to high temperatures due to the characteristics of mica.
