[0025] As a further implementation of this solution, one end of the conductive wire 52 away from the conductive spring 56 is fixedly connected to the power cord 3 connected to the test pen 5, and the conductive wire 52 is fixedly connected to the inner side of the pen housing 51, and the conductive wire 52 is a solid end of the pen housing 51.
