[0030] The side wall of the first connecting block 3 is provided with a clamping ring 13, and the clamping ring 13 is clamped with the rotating rod 9.

[0031] The clamping ring 13 is made of flexible material.

[0032] The clamping ring 2 has an extended semicircular arc at one end.

[0033] The plurality of clamping rings 2 correspond to each other, and the side wall of the extended one end is provided with a mounting hole.

[0034] The mounting holes on every two corresponding clamping rings 2 correspond to each other, and the corresponding mounting holes are used to fix the cable in the corresponding clamping ring 2 by bolts and nuts.

[0035] The clamping ring 2 is clamped on the outer wall of the butt joint cable, then the bolt or the like is passed through the mounting hole on the clamping ring 2, and the matched nut is screwed on the other side of the bolt, so that the clamping ring 2 is tightly clamped on the outer wall of the cable. The side wall of the upper fixing block 1 is provided with the first connecting block 3, the side wall of the lower fixing block 1 is provided with the second connecting block 4, the middle part of the first connecting block 3 is rotatably connected with the first adjusting device, the middle part of the second connecting block 4 is provided with the first mounting hole and is rotatably connected with the first adjusting device. When the device is used for a period of time, the butt joint cable expands or contracts under the action of external force, and a gap appears at the butt joint position. When re-butting is needed, the first adjusting device is rotated and rotated in the first mounting hole. The gap between the first connecting block 3 and the second connecting block 4 is adjusted, so that the cable with gap is re-butt joint. The first mounting hole is a first threaded hole 7, the first adjusting device is a first screw rod 8, and the first threaded hole 7 is threadedly connected. When the first screw rod 8 is not rotated, the gap between the first connecting block 3 and the second connecting block 4 will not change under the action of external force. The upper part of the first adjusting device is provided with the first through hole 5 and is connected with the connecting rod 6. One end of the connecting rod 6 is provided with a groove and is rotatably connected with the rotating rod 9. The worker holds the rotating rod 9 and rotates it to drive the rotating rod 9 and the connecting rod 6 to be in a horizontal state. At this time, the rotating rod 9 is rotated to drive the first screw rod 8 to rotate. The diameter of the rotating rod 9 is smaller than the diameter of the first through hole 5. When the rotating rod 9 is rotated to one side of the fixing block 1, the rotating rod 9 and the connecting rod 6 can be pushed to slide in the first through hole 5, so that one end of the rotating rod 9 slides to one end of the first through hole 5.

At this time, when the cable is subjected to the pulling force on both sides,When the pulling force is transmitted to the first connecting block 3, the second connecting block 4 and the like, the threaded connection of the second screw rod 10 and the nut 12 can assist the first screw rod 8 to fix the second connecting block 4, so that the distance between the first connecting block 3 and the second connecting block 4 is ensured not to change.

[0036] In summary, the electrical engineering cable protection device, when in use, the worker rotates the clamping ring 2, and then clamps the two ends of the interface of the cable that is butted together, and then passes the bolt and the like through the mounting hole on the clamping ring 2, and threads the matching nut on the other side of the bolt, so that the several clamping rings 2 are tightly clamped on the outer wall of the cable. When a certain gap appears in the butt joint part of the cable after a period of use, and the butt joint needs to be repaired, the rotating rod 9 clamped on the snap ring 13 is removed and rotated to be horizontal with the connecting rod 6. At this time, the rotating rod 9 can be rotated to drive the first screw rod 8 to rotate, and one end of the first screw rod 8 rotates in the first threaded hole 7 of the second connecting block 4. At this time, the second connecting block 4 and the first connecting block 3 are close to each other, and the fixed block 1 and the clamping ring 2 at one end of the second connecting block 4 and the first connecting block 3 drive the clamped cable to move and be close to each other, until the butt joint part of the cable is re-butted together and no gap is left. When the cable can be used normally, the rotation of the first screw rod 8 can be stopped. At this time, one end of the rotating rod 9 is clamped on the snap ring 13.
