Safety measure tool for controlling cable core end

The utility model provides a safety measure tool for controlling a cable core end. The safety measure tool comprises a main body, a first mounting hole, a second mounting hole, a fastening part and a sealing part. A first mounting hole matched with the conductive end of the wiring terminal and a second mounting hole matched with the insulating sheath of the wiring terminal are formed in the main body; during operation, firstly, the end of the wire core is inserted into the main body from the end hole of the sealing part, so that the first mounting hole is matched with the conductive end of the wiring terminal, and the second mounting hole is matched with the insulating sheath of the wiring terminal; the inner diameter of the fastening part is smaller than the outer diameter of the insulating sheath, so that interference fit is formed, the tool is a rubber product, the fastening part with high elasticity plays a role in clamping and fixing the insulating sheath of the wiring terminal, and the inner diameter of
