[0022] When in use, the base 501 is fixed to the required external environment of the cable by the No. 2 bolt 502. Two or more structures are connected together in parallel by the fixing plate 504 as needed. The two support arms 1 are connected to the base 501 by the No. 1 bolt 2. An arc-shaped interface is formed at the front end of the two support arms 1. The tensioning device 4 is connected to the interface by the rivet 3. The required fixed cable passes through the fixing ring 402. The material of the fixing ring 402 is rubber, which can increase friction and better fix the cable.
