Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 and Figure 2 , an embodiment provided by the utility model:

[0025] A power cable with a rat-proof function, comprising a base 6, a winch 2 is arranged on the upper part of the base 6, a cable 7 is arranged inside the winch 2, a motor 3 is arranged at the front part of the winch 2, an insulating core 14 is arranged inside the cable 7, a mica tape wrapping layer 9 is arranged outside the insulating core 14, an outer sheath layer 10 is arranged outside the mica tape wrapping layer 9, a rat-proof inner sheath layer 15 is arranged outside the outer sheath layer 10, a nylon sheath layer 11 is arranged outside the rat-proof inner sheath layer 15, a plurality of isolation protrusions 13 are arranged outside the outer sheath layer 10, and a cutting component is arranged on the left part of the winch 2;

[0026] The rat-proof inner sheath layer 15 inside the cable 7 is filled with rat and ant repellent, and the outer side surface of the outer sheath layer 10 is evenly surrounded by a plurality of isolation protrusions 13 for isolation. The rat-proof inner sheath layer 15, the outer sheath layer 10 and the nylon sheath layer 11 are all low-smoke halogen-free sheaths. Through the insulating core 14, the mica tape wrapping layer 9, the outer sheath layer 10, the rat-proof inner sheath layer 15 and the nylon sheath layer 11, the power cable 7 can have a stable rat and ant proof function. By starting the motor 2 3, the output end of the motor 2 3 drives the winch 2 to rotate, and the cable 7 is retracted and released by the winch 2, which saves time and effort for electricians when wiring the cable 7.

[0027] Reference Figure 3 and Figure 4 The cutting assembly includes a fixed frame 8, which is fixedly connected to the upper left side of the base 6, and a motor 1 is fixedly connected to the upper right side of the fixed frame 8, and a threaded rod 20 is fixedly connected to the output end of the motor 1, and a fixed rod 18 is arranged on the inner right side of the fixed frame 8, and a threaded block 21 is threadedly connected to the outer side of the threaded rod 20, and a slider 17 is slidably connected to the outer side of the fixed rod 18, and a mounting plate 12 is fixedly connected to the inner side of the threaded block 21 and the slider 17, and a cutting knife 19 is arranged at the lower part of the mounting plate 12, and a mounting block 16 is arranged at the upper part of the cutting knife 19, and a sliding rod 26 is slidably connected to the inner side of the mounting plate 12, and a sliding block 23 is fixedly connected to the inner side of the sliding block 23, and a triangular block 22 is fixedly connected to the inner side of the sliding block 23, and a spring 25 is arranged on the outer side of the sliding block 23, and a pull ring 24 is fixedly connected to the outer side of the sliding rod 26;

[0028] When the cable 7 needs to be cut, the cable 7 is placed inside the fixing frame 8, the position to be cut is aligned with the cutting through hole, and the motor 1 is started. The output end of the motor 1 drives the threaded rod 20 to rotate, and the threaded rod 20 drives the threaded block 21 to move. The threaded block 21 drives the mounting plate 12 and the cutting knife 19 to move downward, and at the same time drives the slider 17 to slide outside the fixing rod 18, so that the mounting plate 12 can be limited. The cutting knife 19 moving downward can cut the cable 7, thereby replacing manual cutting of the cable 7, which is more time-saving and labor-saving. When the cutting knife 19 needs to be replaced, the pull ring 24 is pulled, and the pull ring 24 drives the slide bar 26 to slide, and the slide bar 26 drives the sliding block 23 to slide inside the mounting plate 12, and the sliding block 23 moves the triangular block 22 to the outside. At this time, by placing the mounting block 16 into the mounting groove inside the mounting plate 12, loosening the pull ring 24, the triangular block 22 moves under the elastic force of the spring 25, and is inserted into the inside of the triangular block 22 for installation. When disassembly is required, only the pull ring 24 needs to be pulled to slide the triangular block 22 out of the mounting block 16, and the cutting knife 19 can be disassembled.

[0029] Reference Figure 1 and Figure 4 The triangular block 22 is slidably connected to the inside of the mounting block 16, the four corners of the bottom of the base 6 are rotatably connected to the universal wheels 5, the upper right side of the base 6 is provided with a push handle 4, and the cutting knife 19 is slidably connected to the inside of the fixing frame 8;

[0030] The cutting knife 19 can be installed by sliding the triangular block 22 inside the mounting block 16 , and the device can be moved to a specified position by setting a push handle 4 to push the universal wheel 5 , and the cutting knife 19 can be slid inside the fixing frame 8 to cut the cable 7 .

[0031] Working principle: When using this device, the cable 7 is composed of an insulating core 14, a mica tape wrapping layer 9, an outer sheath layer 10, a rodent-proof inner sheath layer 15 and a nylon sheath layer 11, which can make the power cable 7 have a stable rodent-proof function, thereby effectively preventing the influence of mice gnawing on the transmission performance of the power cable 7, which is beneficial to ensure the high-performance transmission of the cable 7 and extend the service life of the cable 7. The device is moved to the work site through four universal wheels 5 and a push handle 4, and the motor 2 3 is started, and the winch 2 is started. The cable 7 is retracted and released by the winch 2, which saves time and effort for electricians when wiring the cable 7. When the cable 7 needs to be cut, the cable 7 is placed inside the fixing frame 8, and the position to be cut is aligned with the cutting hole. The motor 1 is started, and the motor 1 drives the thread The rod 20 rotates, the threaded rod 20 drives the threaded block 21 to move, and the threaded block 21 drives the mounting plate 12 and the cutting knife 19 to move downward. At the same time, the slider 17 slides outside the fixed rod 18 to limit the mounting plate 12. The cutting knife 19 that moves downward cuts the cable 7. The cutting mechanism can replace manual cutting of the cable 7, which is more time-saving and labor-saving. When the cutting knife 19 needs to be replaced, the pull ring 24 is pulled, and the pull ring 24 drives the slide bar 26 to slide, and the slide bar 26 drives the sliding block 23 to slide inside the mounting plate 12. The sliding block 23 moves outward with the triangular block 22. By placing the mounting block 16 into the mounting groove of the mounting plate 12 and loosening the pull ring 24, the triangular block 22 is moved by the elastic force of the spring 25 and is inserted into the inside of the triangular block 22 for disassembly and installation.
