DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The principles and features of the present utility model are described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0027] As Figures 1 to 3As shown in the figure, in Embodiment 1 of the present utility model, when performing outdoor cable repair and replacement, first move the device to the upper part of the damaged cable section through the universal wheels. At the same time, hold the bracket 7 and steadily drive the cutting mechanism 15 downward. The positioning slide rail 5 can ensure that the moving trajectories of the bracket 7 and the cutting mechanism 15 are perpendicular. And a square groove 16 for providing a moving space for the bracket 7 is opened on the inner wall of the bottom plate 1. After the bracket 7 carries the cutting mechanism 15 through the square groove 16, the damaged buried cable can be cut from top to bottom. Since the moving trajectories of the bracket 7 and the cutting mechanism 15 are perpendicular, and the whole device has its own weight and is not easy to deviate, so the staff can easily complete the cutting operation of the damaged cable by one person, and ensure the flatness of the cable cut for the subsequent docking process of the new and old cables.

[0028] By installing the first upright column 2 on the top of the bottom plate 1, and installing the second upright column 9 on the top of the adjustable movable adjusting plate 8, and arc-shaped grooves are opened on the tops of the first upright column 2 and the second upright column 9 to adapt to the shape of the cable. After cutting the damaged cable, a new cable needs to be replaced. Therefore, it is necessary to determine the replacement length according to the length of the damaged cable section. For this reason, the first installation component 3 and the second installation component 10 are respectively installed on the tops of the first upright column 2 and the second upright column 9. First, place the new cable in the arc-shaped groove of the first upright column 2, and at the same time pull the cable to move into the arc-shaped groove of the second upright column 9. At this time, rotate the second adjusting screw 101 to drive the second cover plate 102 to move downward to fit and clamp one end of the cable, and adjust the extension distance of the movable adjusting plate 8 according to the length to be cut. After determining the cutting length, rotate the first adjusting screw 32 to drive the first cover plate 33 to also fit and clamp the cable. At this time, the cable is limited by the first upright column 2, the second upright column 9, the first cover plate 33 and the second cover plate 102 and will keep the cable in a straightened state. The staff can also complete the cutting process of the new cable by operating the bracket 7 to drive the cutting mechanism 15 to move downward. At this time, the cutting end faces of the new and old cables are flat and do not require additional cutting and trimming, which has a more convenient wiring feature to complete the replacement of the faulty line.

[0029] In Embodiment 2 of the present utility model, an adjustable cable cutting device, on the basis of Embodiment 1, rolling bearing seats are installed on the tops of the first cover plate 33 and the second cover plate 102, and the first adjusting screw 32 and the second adjusting screw 101 are respectively connected to the two rolling bearing seats to ensure that the first cover plate 33 and the second cover plate 102 will not rotate together when the first adjusting screw 32 and the second adjusting screw 101 rotate.

[0030] It should be noted that grooves are opened at the bottoms of the first cover plate 33 and the second cover plate 102 to increase the contact area with the cable, and the flexible cushion layer is made of rubber material and can deform with the shape of the groove, which can play a role in clamping the cable without causing extrusion damage to the cable core.

[0031] Embodiment 3 of the utility model is an adjustable cable cutting device. On the basis of Embodiment 1 or 2, the movable adjusting plate 8 can be retracted into the interior of the bottom plate 1, and when the second upright column 9 contacts the bottom plate 1, the limit retraction distance is reached. In addition, when the movable adjusting plate 8 is fully retracted, the connecting plate 91 is exactly above the socket 110. Therefore, when transporting the device, to prevent the movable adjusting plate 8 from sliding out, the movable adjusting plate 8 can be completely retracted into the interior of the bottom plate 1, and at the same time, the positioning insertion rod 111 is inserted downward through the connecting plate 91 and extends into the interior of the socket 110 to position the movable adjusting plate 8.

[0032] Embodiment 4 of the utility model is an adjustable cable cutting device. On the basis of any one of Embodiments 1 to 3, convex outer edges are provided on the opposite sides of the bottoms of the two positioning sliding rails 5 to prevent the friction sliders 6 from derailing, and a convenient-to-grip lifting handle is provided on the top of the bracket 7. The shape of the lifting handle is "L" shaped, which is convenient for the operator to hold and control the bracket 7 to drive the cutting assembly 15 to move up and down. The mounting frame 4 is assembled by screwing two plates together. The mounting frame 4 is "L" shaped and can be disassembled for disassembly, installation and maintenance of the positioning sliding rails 5 and connecting components.

[0033] In addition, the trolley frame 13 and the universal wheels at the bottom of the bottom plate 1 can be controlled horizontally or vertically, and can adapt to different operating environments for cable repair and replacement work.

[0034] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
