Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 3 A maintenance device for a power cable skin cutting device comprises a body 1, a rotating rod 2 is vertically rotatably mounted on the upper surface of the body 1, a bearing platform 3 is fixedly mounted on the top of the rotating rod 2, a plurality of mounting openings are circumferentially opened on the upper surface of the bearing platform 3, a first threaded rod 4 is horizontally rotatably mounted in the mounting opening, a slider 5 is threadedly sleeved on the first threaded rod 4, the rotating rod 2 is controlled to rotate by a driving assembly, the driving assembly comprises a driving motor 9 fixedly mounted on the lower surface of the body 1, and an output shaft of the driving motor 9 is fixedly connected to the rotating rod 2;

[0023] A second threaded rod 6 is rotatably mounted on the top of the slider 5, and an L-shaped stop plate 7 is threadedly sleeved on the second threaded rod 6. The stop plate 7 is limited in rotation by a limiting component. The limiting component includes a limiting rod 8 vertically fixedly mounted on the top of the slider 5, and the stop plate 7 is slidably sleeved on the limiting rod 8. A plurality of scales 16 are provided on the upper surface of the bearing platform 3;

[0024] First, determine the size of the blade to be repaired, then place the blade on the supporting platform 3, and then rotate multiple first threaded rods 4. At this time, the slider 5 threadedly sleeved on the first threaded rod 4 will move in the horizontal direction under the restriction of the installation port wall, and control the moving distance of the slider 5 according to the scale 16 until multiple sliders 5 are in contact with the blade. At this time, rotate the second threaded rod 6, and the abutment plate 7 threadedly sleeved on the second threaded rod 6 will move in the vertical direction under the restriction of the restriction rod 8 until the bottom ends of multiple abutment plates 7 are in contact with the upper surface of the blade. The positioning of the blade can be completed. Multiple sliders 5 can position the blade laterally to avoid the blade from moving laterally when the driving motor 9 is rotating with the supporting platform 3, and multiple abutment plates 7 can position the blade vertically to avoid the blade from moving vertically during the rotation of the supporting platform 3. The blade to be positioned can be quickly positioned according to its size, and the positionable blade is no longer of a certain size, thereby improving the practicability of the device.

[0025] An adjusting wheel 10 is fixedly sleeved on the first threaded rod 4, and the surface of the adjusting wheel 10 is provided with anti-slip grooves;

[0026] The first threaded rod 4 can be controlled to rotate by rotating the adjusting wheel 10 , and the anti-slip pattern can increase the friction between the user's palm and the contact surface of the adjusting wheel 10 .

[0027] The upper surface of the body 1 is fixedly installed with a plurality of support plates in a circumferential shape, one end of the support plate is fixedly installed with a mounting ring, a hollow rod 11 with one end designed to be closed is fixedly installed in the mounting ring, a piston rod 12 is inserted in the hollow rod 11 in a sliding seal, an air inlet pipe 13 is fixedly installed at the top of the hollow rod 11, an air outlet pipe 14 is fixedly installed on the surface of the hollow rod 11, and a one-way valve is arranged in both the air inlet pipe 13 and the air outlet pipe 14, the conduction direction of the one-way valve in the air inlet pipe 13 is from the outside to the inside of the hollow rod 11, and the conduction direction of the one-way valve in the air outlet pipe 14 is from the inside of the hollow rod 11 to the outside;

[0029] When the blade is positioned on the supporting platform 3 and the driving motor 9 drives the rotating rod 2, the supporting platform 3 and the blade to rotate, the slide plate 15 threadedly connected to the rotating rod 2 will drive the multiple piston rods 12 to reciprocate in the vertical direction. During the movement, the volume of the multiple hollow rods 11 will continuously change from large to small and then from small to large. When the volume inside the hollow rod 11 increases, the internal pressure decreases, and the gas in the outside will enter the hollow rod 11 from the air inlet pipe 13. When the volume inside the hollow rod 11 decreases, the internal pressure increases, and the gas in the hollow rod 11 will be ejected from the air outlet pipe 14 and act on the surface of the blade, which can remove dust attached to the surface of the blade and prevent dust from affecting the maintenance effect. No additional electric drive device is required, saving costs.

[0030] In the utility model, the size of the blade to be repaired is first determined, and then the blade is placed on the supporting platform 3, and then the plurality of first threaded rods 4 are rotated. At this time, the slider 5 threadedly sleeved on the first threaded rod 4 will move in the horizontal direction under the restriction of the wall of the mounting opening, and the moving distance of the slider 5 is controlled according to the scale 16 until the plurality of sliders 5 are in contact with the blade. At this time, the second threaded rod 6 is rotated again, and the abutment plate 7 threadedly sleeved on the second threaded rod 6 will move in the vertical direction under the restriction of the restriction component until the bottom ends of the plurality of abutment plates 7 are in contact with the upper surface of the blade. The positioning of the blade to be positioned can be completed, and the blade to be positioned can be quickly positioned according to the size of the blade, and the positionable blade is no longer of a certain size, thereby improving the practicality of the device.

[0031] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
