Description
Technical field
The utility model relates to electricity testing screwdriver, specifically a kind of multifunctional screw driver.
Background technology
Electricity testing screwdriver is a kind of important electrician tool, and it has the function of electroscope and screwdriver concurrently, and is widely used in various Electrician Operation.Practice shows, existing electricity testing screwdriver limit due to self structure, the following problem of ubiquity: one, at some Work places (in such as switch cubicle, under night-environment), due to many factors (in such as switch cubicle narrow space and equipment is more, under night-environment ambient light more weak) impact, there is the not smooth problem of illumination in Work places, causes operating personnel cannot see object (such as electric contact to be tested, bolt) clearly in operation process.Now, because existing electricity testing screwdriver does not possess assisting lighting function, just need other support staff to carry out floor light by flashlight, cause the waste of manpower thus.Its two, existing electricity testing screwdriver all carries out electrical verification by the luminescence of neon bulb.But at some Work places (such as under outdoor environment on daytime), due to the impact of many factors (under such as outdoor environment on daytime, ambient light is stronger), whether luminously cause operating personnel cannot see neon bulb clearly in electrical verification process, easily cause electrical verification to occur mistake thus, thus cause operating personnel that electric shock accidents occurs.Therefore, there is the problem of safety in utilization difference in existing electricity testing screwdriver.Based on this, be necessary to invent a kind of brand-new screwdriver, to solve the problem that existing electricity testing screwdriver does not possess assisting lighting function, safety in utilization difference.
Summary of the invention
The utility model does not possess the problem of assisting lighting function, safety in utilization difference in order to solve existing electricity testing screwdriver, provide a kind of multifunctional screw driver.
The utility model adopts following technical scheme to realize: multifunctional screw driver, comprises cutter head, handle of a knife; Cutter head is installed vertically on the front end face central authorities of handle of a knife; Also comprise sound electrical verification and floor light circuit; Described sound electrical verification and floor light circuit comprise button cell, the first triode, the second triode, buzzer, current-limiting resistance, electric capacity, light emitting diode, press button; Wherein, the colelctor electrode of the first triode is connected with the positive pole of button cell; The emitter stage of the first triode is connected with the base stage of the second triode; The emitter stage of the second triode is connected with the negative pole of button cell; The two ends of buzzer are connected with the positive pole of button cell and the colelctor electrode of the second triode respectively; The two ends of current-limiting resistance are connected with the base stage of cutter head and the first triode respectively; The two ends of electric capacity are connected with the base stage of the first triode and the negative pole of button cell respectively; The positive pole of light emitting diode is connected with the positive pole of button cell by press button; The negative pole of light emitting diode is connected with the negative pole of button cell; Buzzer, light emitting diode are all installed on the front end face of handle of a knife; Press button is installed on the side of handle of a knife; Button cell, the first triode, the second triode, current-limiting resistance, electric capacity are all installed on the inside of handle of a knife.
Concrete use procedure is as follows: one, when carrying out operation at the not smooth Work places (in such as switch cubicle, under night-environment) that throws light on, operating personnel presses the button switch, make light emitting diode electrified light emitting and carry out floor light, floor light is carried out by flashlight thus without the need to other support staff, just can ensure that operating personnel can see object (such as electric contact to be tested, bolt) clearly in operation process, thus effectively save manpower.Two, when the Work places (such as under outdoor environment on daytime) that light is around stronger carries out electrical verification, cutter head and electric contact to be tested are touched by operating personnel.If electric contact to be tested has electricity, then the base stage of the first triode becomes high level, the conducting thus of the first triode, and make the base stage of the second triode become high level, the conducting thus of second triode, and make buzzer energising sounding, point out operating personnel's electric contact to be tested to have electricity thus.Therefore, operating personnel, and only need by listening buzzer without the need to by seeing neon bulb, just electrical verification can be carried out, thus avoid because neon bulb cannot be seen clearly whether luminous and cause electrical verification to occur mistake, thus effectively prevent operating personnel electric shock accidents occurs, and then effectively enhance safety in utilization.In electrical verification process, current-limiting resistance plays metering function, thus avoid and causes operating personnel that electric shock accidents occurs because electric current is excessive, thus further enhancing safety in utilization.Electric capacity plays Anti-Jamming.Based on said process, compared with existing electricity testing screwdriver, multifunctional screw driver described in the utility model, by adopting brand new, efficiently solves the problem that existing electricity testing screwdriver does not possess assisting lighting function, safety in utilization difference.
Further, described cutter head is removably installed vertically on the front end face central authorities of handle of a knife; Described cutter head is yi word pattern cutter head, cross cutter head, hexangle type cutter head.During use, cutter head dismounting and change can be yi word pattern cutter head, cross cutter head, hexangle type cutter head by operating personnel according to actual needs, effectively enhances thus and uses flexibility and ease of use.
The utility model is rational in infrastructure, it is ingenious to design, and efficiently solves the problem that existing electricity testing screwdriver does not possess assisting lighting function, safety in utilization difference, is applicable to various Electrician Operation.
