The safety of the operator is improved, the volume is not increased, and the utility model is carried and disassembled easily and has good firmness character.

Description

Illumination electroprobe movable screw cutter
Technical field
The utility model relates to a kind of instrument, is meant especially a kind ofly not only can make screwdriver but also can make the instrument that voltage test pencil also can be made illuminating lamp.
Background technology
Screwdriver is an indispensable work operation tool in the social production practice.Up to now,, only limit to the renovation and the variation of screwdriver handle and knife bar, or be aided with the function that the electroprobe form strengthens its test alternating current, or the combination lighting instrument is in wherein though traditional handicraft function screwdriver is updated and developed.The technology that " screwdriver that can throw light on " of Chinese patent CN 2592341 Y disclosed is the illuminating lamp of handle leading section combination at screwdriver, can solve night or the dark lighting problem of light in the daily life, but it can't test alternating current, bulb needs reflection shield and light gathering is poor, reflection shield makes the compression of handle front space, knife bar is difficult to bear proportionality action power, and there are the intermediate isolating plate in possible in theory and concrete performance difficulty on the structure and fastness is lower.Handle is " zero " type, and rotation is used not smooth.
The utility model content
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and proposes a kind of durable in usely, easy to use, not only can throw light on but also can survey the screwdriver product of electricity.
The purpose of this utility model can reach by following measure: illumination electroprobe movable screw cutter, comprise handle, interconvertible knife bar, the utmost point steel disc that conducted electricity puts the part bonnet, have to be installed with part, bulb bulb, dry cell, the utmost point steel disc that conducted electricity by bulb and to put part bonnet, switch and be fixed on the lighting device that the solid utmost point of conduction is moulded the conduction steel disc on the plate, also have survey electric installation by conduction steel disc, nut, spring, fixed carbon resister, neon bulb and the series connection of touch T cap; Lighting device is arranged in the described handle and survey electric installation, two covering devices do not have that plate is isolated and separate.
Described handle front portion has the knife bar of band cover ear to put forth effort steel bushing, and described knife bar is puted forth effort steel bushing and is fixed in the handle.
Described touch T cap microcephaly inserts handle inside and contacts with neon bulb, and major part is exposed to handle middle part outer surface; Described touch T cap is fixed on the handle.
Described bulb bulb is to put bulb to be installed with in the part, and bulb is installed with part and protects with lampshade.
Described lighting device has the solid utmost point of the conduction of being fixed on to mould both positive and negative polarity conduction steel disc on the plate.
The utility model has following advantage compared to existing technology: compared with prior art, the utility model screwdriver has surveys electricity and illumination functions, has thoroughly solved operator's light working barrier when dark, and knife bar can arbitrarily be changed, convenient disassembly; Can survey the safety guarantee that electricity improves the operator in the operating process, and replacing bulb is easy.

The specific embodiment
By the accompanying drawing that provides embodiment of the present utility model is elaborated:
Shown in Fig. 1~5, illumination electroprobe movable screw cutter comprises handle 18, handle 18 front ends have knife bar to put forth effort steel bushing 11, knife bar is puted forth effort steel bushing 11 and is had knife bar and put forth effort to overlap ear 10, the knife bar 1 that has key inserts key along knife bar jack 19 facing to cover ear 10, handle 18 inside have with knife bar puts forth effort the tight cover 15 of knife bar glue that steel bushing 11 links to each other, and plays fixing movable knife bar effect, inserts good knife bar 1 and can use screwdriver.
Two cavitys are arranged in the handle 18, and a cavity is a lighting device, moulds plate 7 and is divided into two chambers through conducting electricity the solid utmost point, and a chamber is to provide the dry cell 8 of power supply to be hidden in wherein to bulb bulb 3, use be No. 7 dry cells of 2 joints, reach the minimizing volume; Chamber is to be fixed on the solid utmost point of conduction to mould that both positive and negative polarity conduction steel disc 6 on the plate 7 is installed with part 4 with bulb, single-pole single-throw switch (SPST) 5 is connected, and bulb bulb 3 places bulb to be installed with part 4; Another cavity is to survey electric installation, place neon bulb 21, fixed carbon resister 14, spring 13, nut 12 from the inside to the outside successively, and have conduction steel disc 16 to be connected between nut 12 and the movable knife bar 1, the neon bulb 21 other ends contact of innermost layer is the microcephaly of the touch T at handle 18 middle parts cap 17, the major part that touches T cap 17 is exposed to handle 18 middle part outer surfaces, major part by contact touch T cap 17 can detect alternating current.
