[0002] Power fittings are metal accessories that connect and combine various devices in the power system and play a role in transmitting mechanical loads, electrical loads and providing some protection. According to their functions and structures, they can be divided into categories such as suspension wire clamps, tension wire clamps, UT wire clamps, connection fittings, splicing fittings, protective fittings, equipment wire clamps, T-type wire clamps, busbar fittings, and wire pulling fittings. According to their uses, they can be used as line fittings and substation fittings. According to the product units of power fittings, they can be divided into four units: malleable cast iron, forged, aluminum-copper-aluminum, and cast iron, a total of four units.

[0003] Electrical fittings are usually composed of a combination of multiple parts, including some arc clips. In order to facilitate the installation of the arc clips, it is usually necessary to open installation holes symmetrically on both sides of the arc clips. The existing hole opening method is generally to press the arc clip with one hand and use a drill gun to perform a hole drilling operation with the other hand. This method has a large error during operation. Once the arc clip moves, it may cause drilling failure. In addition, when drilling, it is generally necessary to suspend the position where the arc clip is punched. When drilling, the arc clip is easily deformed due to force. Utility Model Content
