The invention discloses an operating rod of a multifunctional grounding device special for meter installation and power connection. The operating rod comprises an inner rod, an upper outer rod and a lower outer rod, the upper outer rod and the lower outer rod are arranged outside the inner rod in a sleeving mode, the inner rod is fixedly connected with the lower outer rod, the upper outer rod can rotate relative to the inner rod, the upper outer rod protrudes out of the end of the inner rod, an adaptor opening is formed in an inner cavity of one end, protruding out of the inner rod, of the upper outer rod and provided with a polygonal inner cavity, and the outer diameter of the adaptor opening is matched with the inner diameter of the upper outer rod. The operating rod further comprises a magnetic sleeve base of a T-type structure, and the periphery of the upper outer rod and the periphery of the lower outer rod are each provided with an insulating handle. The operating rod of the multifunctional grounding device special for meter installation and power connection can be used in cooperation with a detachable rotary fastening connector to install a grounding wire and is simple and ingenious in structure, and two actions can be achieved through one tool.
Description
technical field [0001] The invention relates to a multifunctional special grounding device for meter installation and connection, in particular to an operating lever for a multifunctional special grounding device for meter installation and connection. Background technique [0002] When hanging low-voltage grounding wires in places such as metering cabinets and meter boxes, the position intervals are small, and it is difficult to accurately locate and hang traditional grounding wires, and when hanging, the grounding operation rod cannot meet the specified length due to the small space in the cabinet. Insulated handle A series of practical problems in technology and safety, such as the design of the meter, bring safety risks to the work of meter installation and power connection. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide an operating lever for a multifunctional special grounding de...
