[0021] It should be noted that the composite low-voltage cable 1 uses green environmentally friendly insulation layer and sheath. These materials not only have good electrical properties and physical and mechanical properties, but also ensure that the product does not contain halogen, thus solving the problem of "secondary pollution" that may be formed when the cable burns. At the same time, the green environmentally friendly insulation layer and sheath avoid the production of carcinogenic "dioxin" substances when traditional PVC wires burn;

[0022] A protective frame 5 is provided at one end of the composite low-voltage cable 1, a limiting ring 6 is provided on the inner side of the protective frame 5, a side plate 7 is provided at the end of the protective frame 5, a connecting rod 8 passes through the surface of the side plate 7, and the two ends of the connecting rod 8 are respectively connected to a connecting plate 9 and a clamping block 10, and a spring 11 is sleeved on the outer wall of the connecting rod 8.

[0024] When in use, the connecting rod 8 drives the clamping block 10 to contract by pulling the pull ring 12, so that the composite low-voltage cable 1 can slide along the inner side of the limit ring 6, and then the protective frame 5 is moved to the required cutting position of the composite low-voltage cable 1 for cutting, and the clamping block 10 can be reset under the action of the spring 11 by loosening the pull ring 12, and the symmetrically distributed clamping blocks 10 will clamp and fix the composite low-voltage cable 1. At this time, the protective frame 5 will protect the end of the composite low-voltage cable 1 to prevent the end from contacting and rubbing with the object or the ground;

[0025] It should be noted that when the two clamping blocks 10 are reset simultaneously under the action of the spring 11 , the length of the connecting rod 8 is sufficient for the two clamping blocks 10 to clamp the outer wall of the composite low-voltage cable 1 .

[0026] Working principle: First, by pulling the pull ring 12, the connecting rod 8 drives the clamping block 10 to contract, so that the two clamping blocks 10 are opened, and then the composite low-voltage cable 1 is passed through the inner sides of the two limit rings 6 respectively, so that the composite low-voltage cable 1 can slide along the inner sides of the limit rings 6, and then the protective frame 5 is moved to the required cutting position of the composite low-voltage cable 1 for cutting, and by loosening the pull ring 12, the clamping block 10 can be reset under the action of the spring 11, and the symmetrically distributed clamping blocks 10 will clamp and fix the composite low-voltage cable 1. At this time, the protective frame 5 will protect the end of the composite low-voltage cable 1 to prevent the end from contacting and rubbing with the object or the ground.
