[0036] The connecting band 1 in the embodiment is made of ABS plastic material, which is friendly to materials, changes the original scheme of using metal materials such as iron wire, and carries light through the use of high-strength ABS plastic, without affecting the rail line.

[0037] As Figure 2As shown, the outer periphery of the reflective sleeve 2 in the embodiment is provided with a reflective mark 21. By providing the reflective sleeve, the visual mark is set to be obvious. The reflective mark is provided on the outer periphery of the reflective sleeve, which improves the recognition in night, rainy and foggy weather, and facilitates the monitoring state. As a preferred, the reflective mark in the embodiment is arranged in a red and white color interval scheme. In addition, the axial ends of the reflective sleeve 2 are respectively fixed with a limiting sleeve 22. The limiting sleeve 22 realizes the axial positioning of the reflective sleeve 2 on the outer periphery of the connecting belt 1. The limiting sleeve 22 and the connecting belt 1 can be connected in an interference fit mode, or the limiting sleeve 22 can be connected to each other in a rope knot mode through magic tape.

[0038] As shown, Figures 3-5 The locking part 3 in the embodiment includes a locking sleeve 31 fixed to one side of the connecting belt 1. The locking sleeve 31 is internally provided with a locking hole 311 for the first end part 11 or the second end part 12 to extend into. The side of the first end part 11 or the second end part 12 away from the locking hole 311 is fixed with an end tooth 13. The locking sleeve 31 is movably provided with a locking tooth 34. The end tooth 13 and the locking tooth 34 are correspondingly matched. A tooth-shaped locking mode is adopted. After the connecting belt end is pulled to a suitable position during installation, the operation part is loosened to realize automatic locking. During disassembly, the operation part is pulled up to realize unlocking. The installation and removal are convenient.

[0039] As shown, Figures 4-5 The top of the locking sleeve 31 is fixed with a containing part 32. The containing part 32 is used to provide a lifting containing space for the internal locking tooth 34. The top of the containing part 32 is fixed with a fixed cylinder 33.
