[0015] The present invention has the following beneficial effects: According to the present invention, a buckle sleeve is arranged on the outer wall of the electric pole, and the buckle is fixed by bolts. Then, the cable is pulled so that the cable is inside the round shell, and the telescopic rod is started. The telescopic rod drives the connecting plate to move, and the connecting plate drives the rotating bar to move, and the rotating bar drives the rotating block to move, and the rotating block drives the first rotating plate to move, and the rotating block drives the second rotating plate to move. At this time, the sponge sleeve arranged at the clamping assembly will contact one side of the cable to prevent the square shell at the clamping assembly from moving. Due to the setting of the square shell, during the movement of the second rotating plate, the square box can be driven to approach the cable, the square box drives the sliding plate to move, the sliding plate drives the connecting rod to move, the connecting rod drives the clamping shell to move, the clamping shell drives the second rotating shaft to move, and the second rotating shaft drives the conveyor belt to move. During the movement of the conveyor belt, it can approach the cable, so that the conveyor belt and the sponge sleeve clamp the cable. When the moving distance of the telescopic rod is larger, the clamping effect of the conveyor belt and the sponge sleeve on the cable can be better, so as to prevent the cable from slipping during the construction process.

[0016] (2) According to the present invention, when the conveyor belt continuously clamps the cable, it is subjected to the reaction force of the cable, and the conveyor belt drives the second rotating shaft to move in the opposite direction, the second rotating shaft drives the clamping shell to move in the opposite direction, the clamping shell drives the connecting rod to move in the opposite direction, the connecting rod drives the sliding plate to move in the opposite direction, and the sliding plate moves toward the inside of the square box. During the movement of the sliding plate, it can prevent the outer wall of the cable from being damaged when the cable is continuously clamped, thereby improving the protection effect of the cable. When the conveyor belt approaches the square box, it is subjected to the setting of the rotating frame block, and the rotating frame block rotates around the bottom end of the vertical rod. At this time, one side of the outer wall of the conveyor belt will come into contact with one side of the rotating frame block. The closer the conveyor belt approaches the square box, the stronger the squeezing force of the rotating frame block on the conveyor belt will be, so that the tension of the conveyor belt is increased, and the clamping effect of the conveyor belt on the cable is further improved.

[0017] (3) In the present invention, when the sliding plate moves toward the interior of the square box, the sliding plate drives the rotating rod to move. The rotating rod is limited by the cross bar, and the sliding bar drives the slider to slide along the outer wall of the cross bar. The slider drives the L-shaped rod to move. During the movement of the L-shaped rod, the gear can be driven to rotate. During the rotation of the gear, the rotating sleeve is driven to rotate. The rotating sleeve drives the conveyor belt to rotate. During the rotation of the conveyor belt, the extruded and fitted cables can be moved toward one end of the working shell, so that the cables can be tightened to prevent the cables from becoming loose after installation.

[0018] (4) In the present invention, when the slider moves, the slider drives the extrusion plate to move. During the movement of the extrusion plate, the extrusion plate will come into contact with the sliding bevel sleeve. The extrusion plate squeezes the sliding bevel sleeve to make the sliding bevel sleeve slide toward the inside of the bent rod. During the sliding of the sliding bevel sleeve, since one end of the sliding bevel sleeve and one end of the sliding bevel plate are both inclined, the sliding bevel sleeve will squeeze the sliding bevel plate to make the sliding bevel plate move closer to the cable along the inner wall of the circular shell. Multiple sliding bevel plates clamp the cable, further improving the stability of the cable after tightening and preventing the cable from elastically resetting after tightening.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the sponge cover 456 provided at the clamping assembly 45 will contact one side of the cable 2 to prevent the square shell 453 at the clamping assembly 45 from moving. Due to the setting of the square shell 453, the second rotating plate 457 moves. During the movement, the square box 461 can be driven to approach the cable 2, the square box 461 drives the sliding plate 462 to move, the sliding plate 462 drives the connecting rod 464 to move, the connecting rod 464 drives the clamping shell 465 to move, the clamping shell 465 drives the second rotating shaft 466 to move, and the second rotating shaft 466 drives the conveyor belt 467 to move. During the movement of the conveyor belt 467, it can approach the cable 2, so that the conveyor belt 467 and the sponge cover 456 clamp the cable 2. The greater the moving distance of the telescopic rod 41, the better the clamping effect of the conveyor belt 467 and the sponge cover 456 on the cable 2 can be, thereby preventing the cable from slipping during construction.

The protection effect on the cable 2 is improved, and when the conveyor belt 467 approaches the square box 461, it is affected by the setting of the rotating frame block 479, and the rotating frame block 479 will rotate around the bottom end of the vertical rod 478. At this time, one side of the outer wall of the conveyor belt 467 will be in contact with one side of the rotating frame block 479. The closer the conveyor belt 467 is to the square box 461, the stronger the squeezing force of the rotating frame block 479 on the conveyor belt 467 will be, so that the tension of the conveyor belt 467 is increased, and the clamping effect of the conveyor belt 467 on the cable 2 is further improved.

[0036] When the sliding plate 462 moves toward the inside of the square box 461, the sliding plate 462 drives the rotating rod 471 to move. Limited by the cross bar 473, the rotating rod 471 drives the slider 472 to slide along the outer wall of the cross bar 473, and the slider 472 drives the L-shaped rod 475 to move. During the movement of the L-shaped rod 475, it can drive the gear 476 to rotate. During the rotation of the gear 476, it drives the rotating sleeve 468 to rotate. The rotating sleeve 468 drives the conveyor belt 467 to rotate. During the rotation of the conveyor belt 467, the squeezed and fitted cable 2 can be moved toward one end of the working shell 3, so that the cable 2 can be tightened to prevent the cable 2 from loosening after installation.

[0037] When the slider 472 moves, the slider 472 drives the extrusion plate 477 to move. During the movement of the extrusion plate 477, the extrusion plate 477 will come into contact with the sliding bevel sleeve 483. The extrusion plate 477 squeezes the sliding bevel sleeve 483 to make the sliding bevel sleeve 483 slide toward the inside of the bent rod 481. During the sliding of the sliding bevel sleeve 483, since one end of the sliding bevel sleeve 483 and one end of the sliding bevel plate 485 are both inclined, during the sliding of the sliding bevel sleeve 483, the sliding bevel plate 485 will be squeezed to make the sliding bevel plate 485 approach the cable 2 along the inner wall of the circular shell 482. Multiple sliding bevel plates 485 clamp the cable 2, which further improves the stability of the cable 2 after tightening and prevents the elastic reset phenomenon of the cable 2 after tightening.
