Moreover, under the action of the first spring, the arc plate can be abutted against the side wall of the cable, thereby providing a pre-tightening force for the cable, making the clamping more stable and reliable.

[0017] (2) This type of power fitting for clamping stable iron accessories of power transmission lines is provided with a second pushing mechanism and a limiting mechanism. When clamping, the lever is pushed upward along the rotating shaft by holding the handle. At the same time, the rack is pushed upward by the rotation of the connecting rod, so that the slider moves upward along the guide rod. The third spring is compressed. When the rack moves upward, it pushes the gear and the rotating rod to rotate clockwise, thereby driving the rotating roller and the pressure plate to rotate clockwise. At the same time, when the rotating shaft rotates, it drives the protrusion to rotate synchronously, so that the protrusion is against the inclined surface, which can push the triangular block and the sliding plate to move downward. At the same time, the fourth spring is compressed. After the pressure plate presses the cable tightly, the handle is released. When the cable is disassembled, the sliding plate is pushed downward, and the fourth spring is compressed, driving the triangular block to move downward and disengage from the protrusion.

[0036] The limiting mechanism 9 includes a mounting plate 902 fixedly connected to the side wall of the support frame 701, and a sliding groove 903 is provided on the top of the mounting plate 902, a triangular block 904 is slidably connected in the sliding groove 903, and the triangular block 904 includes a limiting surface 905 and an inclined surface 906, a plurality of array-arranged protrusions 901 are fixedly connected to the side wall of the rotating shaft 702, and a moving mechanism 10 is provided between the triangular block 904 and the mounting plate 902. When the rotating shaft 702 rotates, the protrusion 901 is driven to rotate synchronously, so that the protrusion 901 is abutted against the inclined surface 906, which can push the triangular block 904 to move downward. After the pressing plate 13 presses the cable tightly, the grip 704 is released. At this time, under the action of the moving mechanism 10, The triangular block 904 is moved upward to reset, and under the action of the third spring 604, the protrusion 901 can be abutted against the limiting surface 905, so that the rotating shaft 702 can be limited, and then the pressure plate 13 is limited, which is convenient for clamping and fixing the cable. When the cable needs to be disassembled, the triangular block 904 is moved downward and disengaged from the protrusion 901 through the moving mechanism 10. At this time, under the action of the third spring 604, the rack 502 moves downward, so that the gear 501 and the rotating rod 12 rotate counterclockwise to reset, and then drive the rotating roller 22 and the pressure plate 13 to rotate counterclockwise to reset, so that the cable can be loosened, making the disassembly of the cable more convenient and quick.

[0038] Working principle: When the cable needs to be clamped and fixed, the cable is first placed on the arc plate 17, and then the handle 704 is held by hand to push the lever 703 to rotate upward along the rotating shaft 702. At the same time, the rack 502 is pushed upward by the rotation of the connecting rod 803, so that the slider 603 moves upward along the guide rod 602, and the third spring 604 is compressed. When the rack 502 moves upward, the gear 501 and the rotating rod 12 are pushed to rotate clockwise, thereby driving the rotating roller 22 and the pressure plate 13 to rotate clockwise;

[0039] When the pressing plate 13 abuts against the cable, the arc plate 17 and the moving block 16 are pushed downward, and at the same time, the first spring 203 is gradually compressed. At the same time, when the moving block 16 moves downward, the mounting block 402 and the conical block 403 are driven to move downward synchronously through the T-shaped plate 401. When the conical block 403 abuts against the end of the pushing rod 405, the moving plate 19 is pushed to move in the direction away from the connecting block 302. At the same time, the second spring 303 is compressed. When the conical block 403 passes over the end of the pushing rod 405, the moving plate 19 can be moved and reset in the direction close to the connecting block 302 under the action of the second spring 303. This reciprocating process can make the moving plate 19 reciprocate and drive the bristles 20 to reciprocate, so that the surface of the cable close to the inclined cover 15 can be automatically cleaned.

[0040] After the cleaning is completed, when the pressing plate 13 continues to rotate, the cable can be pressed against the top of the inclined cover 15. During the clamping process, the contact surface between the cable and the inclined cover 15 can be automatically cleaned, which not only makes the cleaning more convenient and quick, but also makes the clamping more stable. In addition, under the action of the first spring 203, the arc plate 17 can be abutted against the side wall of the cable, thereby providing a pre-tightening force for the cable, making the clamping more stable and reliable.

[0041] Furthermore, when the rotating shaft 702 rotates, the protrusion 901 is driven to rotate synchronously, so that the protrusion 901 is abutted against the inclined surface 906, which can push the triangular block 904 and the sliding plate 1002 to move downward. At the same time, the fourth spring 1003 is compressed. After the pressing plate 13 presses the cable tightly, the grip 704 is released. At this time, under the action of the fourth spring 1003, the sliding plate 1002 and the triangular block 904 move upward and reset. Moreover, under the action of the third spring 604, the protrusion 901 can be abutted against the limiting surface 905, so that the rotating shaft 702 can be limited, and then the pressing plate 13 can be limited, which is convenient for clamping and fixing the cable, and is more stable and reliable.

[0042] When the cable needs to be disassembled, the sliding plate 1002 is pushed downward. At the same time, the fourth spring 1003 is compressed and drives the triangular block 904 to move downward and disengage from the protrusion 901. At this time, under the action of the third spring 604, the rack 502 moves downward, causing the gear 501 and the rotating rod 12 to rotate counterclockwise to reset, thereby driving the rotating roller 22 and the pressure plate 13 to rotate counterclockwise to reset, thereby loosening the cable and making the disassembly of the cable more convenient and quick.
