Portable low-voltage electric leakage monitor and monitoring method thereof

The invention relates to the technical field of low-voltage electric leakage monitors, in particular to a portable low-voltage electric leakage monitor and a monitoring method thereof.The portable low-voltage electric leakage monitor comprises a device body, a first fixing block is arranged on the outer wall of one side of the device body, and an adjusting groove and symmetrical guide grooves are formed in the outer wall of the bottom end of the first fixing block; the device has the beneficial effects that a guide rod is pushed upwards to enable the upper part of a positioning ring to be separated from a second fixing block, the positioning ring is rotated outwards to be separated from the second fixing block to open a cover body, an insertion block is pulled down, a cover plate is taken down to take out an internal power supply and a storage assembly, and a pressing plate is extruded to enable one end of an extrusion rod to abut against a notch in the positioning rod to slide down; meanwhile, the positionin
