[0028] In some embodiments, the connecting piece 2 comprises a connecting rod 21 and a plurality of locking rings 22. The connecting rod 21 is detachably connected with the fixed sleeve 1, facilitating the installation and dismounting of the connecting rod 21. The plurality of locking rings 22 are annularly arranged at the end of the connecting rod 21 away from the fixed sleeve 1, and the steel wire rope 3 passes through the plurality of locking rings 22 in sequence, which can reduce the gap between the steel wire rope 3 and the connecting piece 2, improve the stability of the connection between the steel wire rope 3 and the connecting piece 2, prevent the steel wire rope 3 from loosening or falling off during use, and the number of the locking rings 22 is at least three, but is not limited thereto, and the number of the locking rings 22 can be adjusted according to actual needs. The connecting rod 21 and the locking ring 22 can both be made of high-strength steel, and the surface is subjected to corrosion prevention treatment, so as to improve the service life and durability.

[0029] In some embodiments, the fixed sleeve 1 is screw-connected with the connecting rod 21, and the connecting rod 21 can be connected with and detached from the fixed sleeve 1 by rotating the connecting rod, which is simple and convenient to operate.

[0030] In some embodiments, the screwing direction of the connecting rod 21 is clockwise, and when the connecting rod 21 is subjected to a downward force, the connecting rod 21 has a tendency to screw into the fixed sleeve 1, thereby improving the connecting strength of the connecting rod 21 and the fixed sleeve 1 and improving the stability of the steel wire rope 3.

[0031] In some embodiments, the steel wire rope 3 includes a suspension zone 31 and a bending zone 32. The suspension zone 31 can be connected with a safety rope on a worker's body to bear the weight of the worker, thereby providing safety protection for masonry and painting edge and high-altitude operations. The bending zone 32 is arranged at both ends of the suspension zone 31, is parallel to the suspension zone 31, and is provided with a locking assembly 4 between the bending zone 32 and the suspension zone 31.
