The puncture tool has a guiding function, which can be accurately positioned on the cable for operation, ensuring the accuracy and safety of the operation.

[0003] The cable puncture tool can be stably clamped on the 10KV cable through the guide device to prevent errors or movement during operation. When a new cable is led out, the cable puncture tool can be used to pass the new cable through and connect it to the existing cable, which can avoid damaging the original cable protective layer and insulation layer and reduce the impact on the existing cable. When the cable puncture tool uses the guide device, the staff needs to rotate the two limit nuts in sequence, and it is difficult to limit the rotation of the limit nuts at the same time, making it difficult for the staff to quickly use the guide device of the cable puncture tool. Therefore, we proposed a positioning-guided 10KV cable puncture tool. Utility Model Content

At this time, the limit bolt is rotated to disengage the limit bolt from the limit groove, so that the blade quickly disengages from the transmission shaft, and then the new docking block is docked with the docking groove. At this time, the staff uses the limit bolt to limit the new blade with the transmission shaft again, so that the staff can quickly disassemble the blade of the cable puncture device for replacement.
