Detailed description of the invention

Below in conjunction with embodiment, the present invention is described in further detail. Following example are only several specific embodiments of the present invention, but the design concept of the present invention is not limited thereto, all changes utilizing this design that the present invention carries out unsubstantiality, all should within scope.

Embodiment 1

As shown in Figure 1,3, the 220V multi-functional loop electroscope of the present invention, including spring, current-limiting resistance and wire, it clamps axle 1 for axle center with aluminum, its anterior symmetrical insulation crust I 5 and insulation crust II 10 are as test department, its rear portion be insulation hands 13 the body of nippers shape, being in series with spring I 4, current-limiting resistance, neon tube, spring II 3 and spring III 9, current-limiting resistance, neon tube, spring IV 12 in insulation crust I, II 5,10 from top to bottom respectively, described spring I 4 is connected with examination contact 6 one end leaning out insulation crust I 5 top; Spring II 3 is connected with hands touched electrode 2 by wire, and the spring III 9 of the other end is connected with the draw point I 8 being fixed on insulation crust II 10 side by wire; Spring IV 12 is connected with another draw point II 11 being fixed on insulation crust II 10 side by wire; insulation crust II (10) is provided with draw point protection block (7) at the outer end adapting position being provided with draw point, and in described insulation crust, the cross section of I, II 5,10 all adopts tetragon.
