Description
Technical field
A kind of multi-functional secondary Speical screwdriver is the utility model is related to, belongs to electrical equipment technical field.
Background technology
At present, the use of screwdriver is now conventional type screwdriver, its application method is single, is only used for parbuckle screw, does not have
It is standby multi-functional.Simultaneously in relay protection professional work, signal checking work is often carried out, now also needs to prepare one in addition
Signal checks line, for short circuit desired signal both positive and negative polarity so as to the upper number of delivering letters.Certain defect regarding to the issue above be present：
1st, traditional screwdriver application method is single, does not possess multi-functional；
2nd, in the work of relay protection specialty checking signal, a single signal verification line need to be prepared, and check line
It is mostly conventional test line, does not possess defencive function, if being shorted to dc source both positive and negative polarity, power positive cathode can be caused short
Road, accident of human electric shock may be caused when serious, there is certain danger.
If the 3rd, encountering trip signal by mistake in checking signal is likely to result in mistrip.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than：One kind is provided to solve
Drawbacks described above, combine conventional screw-driver in order and relay protection specialty signal verification function, and more work(with insurance function
Can secondary Speical screwdriver.
Technical scheme is used by the utility model solves its technical problem：Multi-functional secondary Speical screwdriver includes knife
Handle and cutter hub, handle of a knife are hollow type structure, are fixedly installed the telescopic coil of wire in handle of a knife, signal core is wound with the telescopic coil of wire
To line, one end of signal verification line is located at the outside of the end of handle of a knife, and the other end of signal verification line is through light emitting diode and guarantor
The end of cutter hub is connected to after dangerous silk, wherein signal verification line is provided with block in the wire body outside handle of a knife.
The lid of openable is installed on described handle of a knife, lid positioned at the corresponding telescopic coil of wire, light emitting diode and
The opening position of fuse.It is easy to the replacing to fuse etc..
Described lid respective leds and the opening position of fuse are provided with transparent viewing port.Can be with apparent
Observe the state of light emitting diode and fuse.
Use principle is：
Usually, the utility model can regard normal screws knife and use, when needing to carry out signal checking work, Ke Yitong
Cross block to extract signal verification line out, the front end of line and cutter hub is checked by signal, the both positive and negative polarity of desired signal is shorted to, enters
Row signal is checked, and in the course of the work, when excessive by electric current, blown fuse, realizes defencive function；In checking signal
When, when have electric current by when, light emitting diode 4 is luminous, can judge whether external circuit connects reliably accordingly；Work as fuse simultaneously
During fusing, external circuit disconnects, and light emitting diode can not be lighted luminous, can determine whether fuse is normal accordingly.
Beneficial effect is possessed by the utility model：The utility model is rational in infrastructure, practical function, for relay protection
The live real work of specialty has practicality, and it possesses the conventional use of conventional screw-driver in order, at the same time possesses signal verification
Function, and there is insurance function, for preventing that personnel from getting an electric shock and anti-locking apparatus mistrip has reliable protection function.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, handle of a knife；2nd, cutter hub；3rd, the telescopic coil of wire；4th, signal verification line；5th, light emitting diode；6th, fuse；7、
Block；8th, lid；9th, transparent viewing port.
Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, multi-functional secondary Speical screwdriver, including handle of a knife 1 and cutter hub 2, handle of a knife 1 is hollow type structure, knife
The telescopic coil of wire 3 is fixedly installed in handle 1, signal verification line 4 is wound with the telescopic coil of wire 3, signal checks one end position of line 4
In the outside of the end of handle of a knife 1, the other end of signal verification line 4 is connected to cutter hub 2 after light emitting diode 5 and fuse 6
End, wherein signal verification line 4 are provided with block 7 in the wire body outside handle of a knife 1.
The lid 8 of openable is installed, lid 8 is positioned at the corresponding telescopic coil of wire 3, light emitting diode 5 and protects on handle of a knife 1
The opening position of dangerous silk 6.The respective leds 5 of lid 8 and the opening position of fuse 6 are provided with transparent viewing port 9.
Use principle is：
Usually, the utility model can regard normal screws knife and use, when needing to carry out signal checking work, Ke Yitong
Cross block 7 to extract signal verification line 4 out, the front end of line 4 and cutter hub 2 is checked by signal, is shorted to the positive and negative of desired signal
Pole, signal verification is carried out, in the course of the work, when excessive by electric current, fuse 6 fuses, and realizes defencive function, and work as
It can be changed after damaging by opening lid 8；In checking signal, when have electric current by when, light emitting diode 4 is luminous,
It can judge whether external circuit connects reliably accordingly；Simultaneously when fuse 6 fuses, external circuit disconnects, the nothing of light emitting diode 4
Method is lighted luminous, can determine whether fuse 6 is normal accordingly.
