Tool for measuring fusing current of micro wire

The utility model belongs to the technical field of wire detection, and particularly relates to a tool for measuring the fusing current of a miniature wire, which comprises a detection box and a power supply device, the positive electrode and the negative electrode of the power supply device are both connected with wires, and the inner side of the detection box is connected with two movable seats in a sliding manner; during detection, the two movable seats are pulled through the connecting plate, the two ends of the wire rod are clamped in the two mounting seats respectively, then pulling to the connecting plate is relieved, the connector is driven to extrude and fix the wire rod between the fixing seat and the connector when the tension spring retracts, and at the moment, power equipment can be connected with a power source to conduct fusing detection on the wire rod. After fusing detection is completed, the connecting plate is pulled, the fused wire rod is not limited at the moment and directly penetrates through the communicating groove to enter the collecting box to be collected, so that the fused wire rod does not affect next measurement, and replacement operation is quite easy while the wire rod is fixed stably.
