At present, the domestic 10kV distribution network live working has been vigorously developed, and the technology is becoming more and more mature. In the insulated operating rod operation method, the operator uses foot buckles to climb to a certain height, and then uses an insulated operating rod to operate. During the operation, it is necessary to push and pull the wires, and adjust the position of the wires and the operators to facilitate the work of the live working personnel;

[0003] The existing Chinese patent announcement number is: CN208986482U, which discloses a double-head push-pull hook specially used for an insulating operating rod. When working with live wires, it is convenient to adjust the position of the conductor and the operator, which is convenient for the live wire operator to carry out work and reduces the labor intensity of the live wire operator. It can also be used during power outage operations. In this technical solution, the double-head push-pull hook and the supporting insulating operating rod are connected and fixed by bolts, which requires a specific wrench tool during disassembly and assembly, which is inconvenient and affects the work efficiency of the personnel. For this reason, we propose a double-head push-pull hook specially used for an insulating operating rod. Utility Model Content

[0025] The double-head push-pull hook for the insulating operating rod provided by the utility model is preferably implemented as follows Figures 1 to 6 As shown: a double-head push-pull hook specially used for an insulating operating rod, comprising a double-head push-pull hook 1 and a supporting insulating operating rod 3, a supporting seat 2 is fixedly installed on the outer side of the double-head push-pull hook 1, and a connecting mechanism 4 is arranged between the supporting seat 2 and the supporting insulating operating rod 3;

[0026] The connecting mechanism 4 includes a slot 401, a card plate 403 and a rotating shaft 404. The slot 401 is provided at the top of the supporting insulating operating rod 3. The supporting seat 2 is inserted into the slot 401. A contraction slot 402 is provided near the top of the supporting seat 2. A rotating slot 408 is provided on the contraction slot 402. The rotating slot 408 is provided on the supporting seat 2. The card plate 403 is provided in the contraction slot 402. A card slot 1 410 is provided on the inner wall of the slot 401. The card plate 403 is connected to the card slot 1 410. The rotating shaft 404 is fixedly installed on the top of the card plate 403. The rotating shaft 404 passes through the top of the inner wall of the shrinkage groove 402 and extends into the rotating groove 408, and the outer wall of the rotating shaft 404 is rotatably connected to the support seat 2 through a bearing. A shaft groove 412 is provided at the top of the rotating shaft 404, and a connecting shaft 405 is inserted in the shaft groove 412. A spring 406 is fixedly installed between the bottom end of the connecting shaft 405 and the inner wall of the shaft groove 412. A rotating plate 407 is fixedly installed at the top of the connecting shaft 405. A clamping block 409 is fixedly installed on the inner wall of the rotating groove 408. A second clamping groove 411 is provided on the rotating plate 407, and the clamping block 409 is clamped in the second clamping groove 411.

[0027] Specifically, in the above technical solution, when the double-headed push-pull hook 1 is in use, the support seat 2 is inserted into the slot 401. When the support seat 2 is inserted into the bottom end of the slot 401, the rotating plate 407 is pulled upward, and the rotating plate 407 drives the connecting shaft 405 to move upward. The connecting shaft 405 stretches the spring 406. When the rotating plate 407 moves upward, the clamping block 409 is disengaged from the clamping slot 1 410, so that the clamping block 409 no longer limits the rotating plate 407. At this time, the rotating plate 407 is rotated, and the rotating plate 407 drives the connecting shaft 405 to rotate. The connecting shaft 405 drives the rotating shaft 404 to rotate through the shaft groove 412. The rotating shaft 404 drives the card plate 403 to rotate, so that the card plate 403 rotates 90°, so that the card plate 403 is clamped in the clamping slot 2 411, so that the card plate 403 is aligned with the card slot 2. The support seat 2 is limited and fixed, and then the rotating plate 407 is released. The connecting shaft 405 will drive the rotating plate 407 to move downward under the restoring force of the spring 406, so that the block 409 is again inserted into the slot 410 at the current position, and the rotating plate 407 is limited, thereby completing the connection and fixation between the double-headed push-pull hook 1 and the supporting insulating operating rod 3. Through this mechanism, it is convenient for personnel to disassemble and assemble the double-headed push-pull hook 1 and the supporting insulating operating rod 3, thereby improving the work efficiency of personnel, and solving the problem that in the prior art solution, the double-headed push-pull hook 1 and the supporting insulating operating rod 3 are connected and fixed by bolts, resulting in the need for specific wrench tools during disassembly and assembly, which is inconvenient and may affect the work efficiency of personnel.

[0028] Furthermore, the cross-sections of the bottom ends of the connecting shaft 405 and the shaft groove 412 are rectangular, and the connecting shaft 405 and the shaft groove 412 are adapted to each other;

[0029] By setting the connecting shaft 405 and the shaft groove 412 to be rectangular, the connecting shaft 405 can drive the rotating shaft 404 to rotate through the shaft groove 412 .

[0030] Further, the clamping plate 403 is adapted to the contraction slot 402 and the second clamping slot 411;

[0031] Wherein, by providing the clamping plate 403 , the clamping plate 403 can be clamped into the second clamping slot 411 , thereby limiting and fixing the support seat 2 .

[0032] Furthermore, the number of the card blocks 409 is two, the number of the card slots 410 is several, and the card blocks 409 are matched with the card slots 410;

[0033] Among them, by setting the clamping block 409, the clamping block 409 can be clamped into the clamping slot 1 410, so that the rotating plate 407 can be limited. Embodiment 2

[0034] On the basis of the first embodiment, the double-head push-pull hook for insulating operating rod provided by the utility model is preferably implemented as follows Figures 1 to 6 As shown: a wall pad 5 is fixedly installed on the inner wall of the double-head push-pull hook 1, and the material of the wall pad 5 is wear-resistant rubber. A grip sleeve 6 is fixed near the bottom outer wall of the supporting insulating operating rod 3, and the material of the grip sleeve 6 is PVC soft rubber.

[0035] Specifically, in the above technical solution, by setting a wall pad 5, it is possible to avoid hard contact between the double-headed push-pull hook 1 and the live wire during use, reduce wear, and provide a certain degree of protection for the live wire. By setting a grip sleeve 6, the friction between the person's hand and the supporting insulating operating rod 3 can be increased, which is convenient for the person to operate and has strong practicality.
