It is strong and weak regardless of indoor and outdoor light that the three Dian band sounds are surveyed electricity, surveys electricity and just ring, and be super loud.With the ear sense of hearing, faster and more convenient operation.

Four Dian listen sound speed rhythm, or see and just can judge electric insulation degree by glittering speed, faint electric leakage, convenient detection, difference.

Five Dian high-strength insulation glue handles, withstand voltage 1000V, does not exist fiber crops feel while surveying electricity to feel.

Six No. 45, Dian cutting edges of a knife or a sword are firm, quench hot, and nipper plier is durable in use.

The little bottle opener primary screw of seven Dian degree of tightness, freely, little jack inspection electricity is convenient in assembling.

Eight Dian pincers, survey, and revolve, cut going along with on the other hand, electrician companion, herbal.

The specific embodiment

Known according to Fig. 1 to Fig. 6, the utility model is comprised of caliper, insulated handle, a rim of the mouth, and the front end metal position of caliper 1 is for surveying electric live wire end, and caliper insulated handle 2 is provided with the ground terminal 9 contacting with human body;

Between described live wire end and ground terminal, be provided with can be luminous device 3 or device 4 that can sounding;

In described device 3 that can be luminous, be provided with light-emitting component 5, and for the illuminating circuit 7 of light-emitting component work; Described can be provided with sounding component 6 in the device 4 of sounding, and supplies the phonation circuit 8 of sounding component work;

Described device 3 that can be luminous, and for the illuminating circuit of light-emitting component work, and described device 4 that can sounding, and for the phonation circuit of sounding component work, be all arranged on insulated handle 2;

The leading portion of described caliper 1 is made into a rim of the mouth 10 of in-line.

Described caliper 1 is nipper plier or flat nose pliers.

Ground terminal 9 on described caliper insulated handle 2, is one to be arranged on the lip-deep bar shaped conductive layer of handle 2, and bar shaped conductive layer connection metal handle 2.

Described device 3 that can be luminous is arranged on the handle 2 front ends tiger's jaw place of shaking hands, and is an outstanding round platform, and the fixture 51 of installing light emitting element 5 is set in round platform, and light-emitting component 5 belows arrange luminous circuit board 52.

Described device 4 that can sounding is arranged on the handle 2 front ends tiger's jaw place of shaking hands, and is an outstanding cavity round platform, and sounding component 6 is set in round platform, and sounding component 6 belows arrange phonation circuit plate 61.

Described illuminating circuit and phonation circuit are by bridge rectifier D ₁connection is by trigger tube DW ₁, DW ₂with monocrystalline silicon T ₁the circuits for triggering that form, then connect light-emitting component 5 or sounding component 6 by triggering output.

Circuit working principle of the present utility model:

As shown in Figure 5, pass through R ₁d ₁whole bridge and hand touch end and form a basic rectification circuit, its trigger tube DW ₁, DW ₂with T ₁monocrystalline silicon forms circuits for triggering, to DY information ring device, provides the voltage that sends the sound, and its course of work is: when staff contact touches end, just at A, B end forms DC voltage, and its voltage is added in DW ₁, DW ₂and T ₁on the circuits for triggering that form, due to DW ₁, DW ₂under the effect of voltage stabilizing threshold value, at T ₁g end produce trigger voltage, T ₁conducting, passes through R ₂resistance, leakage current, the very fast decline of voltage, T ₁g end decompression, conducting cut-off.When voltage rises again, T ₁g end again trigger T ₁conducting, goes round and begins again, and at DY information ring device end, forms alternating voltage, produces the sound, because human body resistance and earth resistance change with condition, and the voltage of the testing circuit that can raise, quickening DW ₁, DW ₂, T ₁threshold rates, same sound and rhythm is accelerated, vice versa.

During due to survey electricity, the decay by interior circuit choked flow (guaranteeing that staff touches safety) with human body and earth resistance, electric current is just very faint, and the DY information ring device sound is affected.Increase a sound-aid cavity to information ring device here, make the sound larger, louder.

As shown in Figure 6, at A, the voltage that B end forms, is full of C ₁electric capacity, its voltage rises, at DW ₁, DW ₂under the threshold function of trigger tube, trigger T ₁g end, T ₁monocrystalline silicon conducting, LED light emitting diode D ₁conducting is luminous, release current, voltage drop, C ₁electric capacity continues charging, raises voltage, T ₁monocrystalline silicon is conducting again, D ₁conducting is luminous, and so circulation, forms the luminescence process glimmering, and makes target more eye-catching, at LED luminous tube epimere, loads onto prism, and light-emitting area is expanded, and is not subject to daylight impression, D ₃accomplish the effect of voltage stabilizing here.
