[0044] Embodiment 4

[0045] like Figure 5 As shown, the utility model proposes a device for preventing loose strands of cable steel core aluminum stranded wire. Compared with the third embodiment, in this embodiment, the cutting component includes

[0051] The bottom of the bundling box 1 is connected to an L-shaped rod 24, which is symmetrically arranged on both sides of the cutting blade 21. A cleaning brush 25 is connected to the L-shaped rod 24. The support of the L-shaped rod 24 keeps the cleaning brush 25 on both sides of the cutting blade 21. When the cutting blade 21 moves, the bristles of the cleaning brush 25 contact it to clean its surface, thereby preventing metal debris generated by cutting from adhering to the cutting blade 21.

[0052] In summary, when the utility model is used, the cable is passed through the opening on the bundling box 1, and then the staff starts the motor 3 to make the motor 3 drive the coaxial bidirectional screw 4 to rotate. When the coaxial bidirectional screw 4 rotates, it will drive the sliding sleeve 5 to move synchronously along the axis of the coaxial bidirectional screw 4. The moving plates 6 between the sliding sleeves 5 can drive the clamping plates 2 to approach each other to clamp the cable; when facing cables of different diameters and sizes, pulling the pull ring can drive the moving sheet 11 and the moving rod 9 to move, and the moving sheet 11 stretches the first elastic member 1 2, the moving rod 9 is moved out of the positioning hole 10 provided on the clamping plate 2, and the clamping plate 2 can be disassembled at this time; after the clamping plate 2 is disassembled, the sliding block 13 is pushed to move, and the sliding block 13 moves in the sliding groove 14. The grooves on both sides of the sliding block 13 contact with the limiting balls 18, and the sliding block 13 compresses the length of the second elastic member 16 to make the limiting balls 18 shrink into the accommodating groove 17. After the limiting balls 18 shrink, they lose the restriction on the sliding block 13, and the sliding block 13 can be replaced. When this happens, the arc groove on the sliding block 13 fits the shape of the cable.

[0053] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
