[0001] The invention relates to the technical field of power auxiliary tools, and in particular to a device for fixing a wire for replacing a power meter. Background Art

[0002] Electric energy metering devices are indispensable measuring instruments used in the process of supply, use and power generation. Electric energy metering ensures that the economic benefits of the power industry in each link of power generation, transmission, distribution and sales can be reasonably distributed; ensures that electricity customers pay reasonable electricity bills according to their electricity consumption; and provides detailed data for investigating and punishing illegal and breach of contract electricity use, preventing electricity theft, and handling electricity bill disputes.

[0003] The current electricity demand is growing year by year, and the amount of new electricity metering equipment installed is increasing year by year. The workload of periodic inspection and replacement is increasing. There are many wiring terminals and the wiring is complicated. It is inconvenient to thread the wires when changing the meter.
