By coordinating the winding reel, chute, rod, column, ring, groove, disc, first bolt, and through groove, the disc can be fixed after rotation by inserting the first bolt into multiple grooves at the winding reel. When the disc drives the through groove to rotate, the through groove will extend the rod outwards in the chute with the help of the column, thereby increasing the diameter of the winding reel. This allows for the accommodating of more rope, making it convenient to change the rope capacity according to different research and exploration tasks, and to carry out traction work at different depths. To a certain extent, it can meet the needs of various depths.
