A wire groove 18 for the cable 17 to pass through is provided on one side of the installation pipe 1, so that the installation pipe 1 can be sleeved on the cable 17 during operation and removed from the cable 17 after the operation is completed. Both ends of the connecting plate 3 are connected to both sides of the wire groove 18, thereby preventing the installation pipe 1 from detaching from the cable 17 during the operation and improving safety. Exemplarily, there are two connecting plates 3, and the two connecting plates 3 are arranged at intervals along the axial direction of the installation pipe 1. The two pulleys 15 are arranged at intervals along the axial direction of the installation pipe 1 and are respectively rotatably installed in the inner cavity of the installation pipe 1. Exemplarily, the pulley 15 is installed on the pulley shaft 2 and can rotate around the pulley shaft 2, and both ends of the pulley shaft 2 are fixedly connected to the installation pipe 1. Exemplarily, the pulley 15 is installed on the pulley shaft 2 through bearings. After the installation pipe 1 is sleeved on the cable 17 during operation, the two pulleys 15 simultaneously support on the cable 17, which can not only bear the load from the pulley 15 through the cable 17, but also enable the pulley 15 to roll on the cable 17. Since the outer peripheral surface of the pulley 15 has a groove, when the pulley 15 supports on the cable 17, the cable 17 is located in the groove, which can prevent the pulley 15 from slipping off the cable 17 during the rolling process and improve safety. Exemplarily, the pulley 15 can be fabricated from ABS engineering plastics. The clamping mechanism is arranged in the installation pipe 1 and is used to clamp the cable 17, thereby firmly fixing the entire safety sleeve ring on the cable 17.
