The opposite side of block is provided with detection module.
As further describing for above-mentioned technical proposal：
The preceding surface of described device body is provided with display screen, and the lower section of the display screen is provided with key panel.
As further describing for above-mentioned technical proposal：
The shell both sides upper end of described device body symmetrically offers teeth groove, and is slided in teeth groove and be connected with button.
As further describing for above-mentioned technical proposal：
The button is provided with two altogether, and two buttons are symmetrical on the vertical center line of device body.
As further describing for above-mentioned technical proposal：
It is described with device body is matching used expansion link, and expansion link is connected in stopper slot by elastic buckles.
As further describing for above-mentioned technical proposal：
The output end of the key panel is electrically connected with the input of voltage changing module and detection module respectively.
In the present invention, the portable electric leakage safety detection device, it mainly produces higher voltage by voltage changing module, so
Wire clamp is folded up in cable part to be detected afterwards, judges whether leak electricity herein by the size of the current value flowed through, in wire clamp
When being clipped on cable, button is that card is placed in teeth groove, so just when in use, then need not hold wire clamp portion
Point, the possibility of electric shock is reduced, and connection buckle is provided with the back of the detection means, can card insertion insulation in connection buckle
Expansion link, it is because human body is from farther out, then safer so in the detection to some higher line sections and relatively hazardous line segment,
For traditional portable electric leakage safety detection device, the detection means use is more convenient, and security is higher, practical
Property is stronger.
