Claims

[Scope of claim for utility model registration] 1. A tool that is used to replace electrical equipment such as a watt-hour meter so that the work can be carried out without power outage, and that is a tool that can be drawn out outside of the watt-hour meter. a presser foot having a plurality of parallel grooves into which the insulated conductor can be housed, and a blade portion at the tip capable of making cuts into the insulation portion of the insulated conductor at positions corresponding to the grooves of the presser foot. A switching mechanism that has a hole (hereinafter referred to as a screw hole) for inserting a cutting member such as a screw (hereinafter simply referred to as a screw) and electrically connects and disconnects the screws; The main body includes a drive mechanism, a part of which is exposed to the outside of the main body for driving the screws, and a display mechanism, a part of which is exposed to the outside of the main body to display the connection status between the screws. , when using the tool, the presser stand and the main body are brought into contact with both sides of the insulated conductor, and both ends of the presser stand and the main body are clamped to integrate the presser stand and the main body; and the tip of the screw inserted into the screw hole of the main body makes a cut in the insulated part of the insulated conductor to establish continuity between the conductor part inside the insulated conductor, the screw, and the switching mechanism. An uninterruptible tool characterized in that it is constructed in such a way that it can be removed. 2. The uninterruptible tool according to claim 1, wherein the drive mechanism is operated manually.
