Abstract
The invention discloses a test pencil which comprises a test pencil body, wherein a screwdriver replacing neck is arranged at the front end of an insulating handle of the test pencil body, 2-5 electronic luminescent tubes are installed on the front end face of the periphery of the neck, a battery installation groove opened toward one side is arranged above a resistance wire and a neon bulb in the handle, a battery is installed in the battery installation groove, and electrodes of the battery installation groove are connected with the electronic luminescent tubes through leads. A charging connector is installed in the battery installation groove, a charging port is arranged at the rear end of the handle, an alternating current charger is installed in the handle between the charging port and the charging connector through leads, and the battery in the battery installation groove is rechargeable. The test pencil can be used not only in places having good light but also in dark places, a screwdriver can be replaced randomly any time according to the shape of a screw neck in use, and the test pencil brings great convenience for operation.
Description
Technical field:
The present invention relates to circuit test, particularly a kind of have several functions, a test pencil easy to use.
Background technology:
Present test pencil all is that a front end at insulated handle is equipped with a screwdriver contact, and neon bulb is installed in handle, is communicated with resistance in the handle between neon bulb and screwdriver contact.This traditional test pencil because there not being lighting device, is not easy to use at night or the bad place of light, and coping screw cutter contact is stationary structure simultaneously, also is not easy to different screws is carried out the degree of tightness operation, and function singleness is used inconvenient.
The invention task:
The purpose of this invention is to provide and a kind ofly not only had illumination functions, but also can change the Multifunction screw-driver with voltage tester of screwdriver contact.
Technical scheme of the present invention is finished as follows, it includes a test pencil, it is characterized in that: the insulated handle front end at test pencil is provided with a screwdriver replacing draw-in groove, front end face at the draw-in groove periphery is equipped with 2-5 luminous electronic tubes, above handle internal resistance wire and neon bulb, be provided with one to the battery mounting groove of a side opening, in the battery mounting groove, battery is installed, between the electrode of battery mounting groove and luminous electronic tube, is connected with wire.In the battery mounting groove charging connector is installed, is provided with charging inlet at handle rear end, be connected and installed with an alternating current charging device through wire respectively in the handle between charging inlet and charging connector, the battery in the battery mounting groove is a kind of rechargeable battery.
The present invention not only can use in the place of well lighted, also can use in the place of dark, can change at any time screwdriver according to the shape of screw draw-in groove during use, brings great convenience to operation.
Description of drawings:
Fig. 1 is structural representation of the present invention.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the present invention is improvements over the prior art, it is the replacing draw-in groove 7 that is provided with a screwdriver 1 at the front end of a test pencil insulated handle 4, front end face at the draw-in groove periphery is equipped with 2-5 luminous electronic tubes 2, above handle internal resistance wire 8 and bubble 9 thereof, be provided with one to the battery mounting groove 3 of a side opening, between battery mounting groove and luminous electronic tube, be connected with wire.In the battery mounting groove, charging connector is installed, be provided with charging inlet 6 at handle rear end, be connected and installed with an alternating current charging device 5 through wire respectively in the handle between charging inlet and charging connector, the battery in the battery mounting groove is a kind of rechargeable battery 10.It is many that the present invention has function, the advantage of convenient working.
