工具。[Scope of Claim for Utility Model Registration] 1. A tool that enables the replacement of electrical equipment such as a watt-hour meter (hereinafter simply referred to as a watt-hour meter) without causing a power outage. , a tool equipped with a cutting member such as a screw (hereinafter simply referred to as a screw) having a blade portion at the tip capable of cutting into the insulation coating portions of the power source side and load side external insulation coating conductors of the power meter. The external insulated conductor is stored between the main body and the tool rest pressed by the tool body, and the blade of the screw makes a cut in the insulated part of the insulated conductor, and the external insulated conductor is inserted into the power supply side of the watt-hour meter. In an uninterruptible tool in which the conductor and the load-side conductor are electrically connected by a bypass circuit in the tool main body, and replacement work can be performed without a power outage, the bypass circuit is electromagnetically linked to the bypass circuit at once. A current injection section provided to intersect with each other, a pulse generation section connected to the current injection section and applying a pulse voltage to the current injection section, and a pulse generation section provided so as to be electromagnetically interlinked with each of the bypass circuits. a current detecting section, connected to the current detecting section, and causing a current to flow through the bypass circuit due to a pulse voltage applied from the pulse generating section to the current injection section and detecting the current when the current is detected by the current detecting section; An uninterruptible tool with a display function, characterized by comprising a display section for displaying information. 2. The uninterruptible tool with display function according to claim 1, further comprising an impedance matching circuit installed in the bypass circuit.
