Background technology
Voltage test pencil is again test pencil, is the whether charged electrician tool of a kind of conventional testing circuit. The conventional configurations of currently known voltage test pencil is sequentially connected in series forms for surveying electrical contact, current-limiting resistance, neon tube and hands touched electrode; Test measured object whether charged time principle be: compare measured object relative to the earth whether there is higher voltage, measured object with voltage higher than the earth time, neon tube starter; When measured object is not charged, neon tube is starter not. Concrete operations are to be contacted with measured object by survey electrical contact, human contact's hands touched electrode, form test loop, and then whether starter determines that whether measured object is charged to observe neon tube. But existing voltage test pencil survey electrical contact a part by plastic packaging at insulation crust, survey electrical contact and not there is mobile or flexible function, such voltage test pencil needs more space when carrying, and survey what electrical contact was always up exposing in carrying process, easily scratch carry use carry instrument, carry and there is inconvenient present situation.
Summary of the invention
In view of this, it is contemplated that propose a kind of pressing voltage test pencil, it is possible to by controlling the contraction surveying electrical contact by flowing mode with overhanging, contribute to being shunk by sharp-pointed survey electrical contact in carrying process, carry and more save space, prevent plowing from carrying instrument and easy to use simultaneously.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of pressing voltage test pencil, including the survey electrical contact being sequentially connected electrically in insulation crust, current-limiting resistance, neon tube and hands touched electrode, described hands touched electrode includes engaging lock dog, press connecting rod and hands contact, the lateral wall of described engaging lock dog is provided with the engaging convex ridge of the ridged evagination of annular space distribution, the described two ends pressing connecting rod engage lock dog with described respectively and described hands contact is rotationally connected, described insulation crust inwall is provided with engaging the inwardly projecting convex shoulder of described engaging convex ridge, the front center of described insulation crust has the draw-in groove of turnover of stretching for described survey electrical contact, on the lateral wall of described insulation crust corresponding within the position of described neon tube have loophole, it is provided with the first spring between described survey electrical contact and described current-limiting resistance, it is provided with the second spring between described neon tube and described engaging lock dog.
Further, the front end of described survey electrical contact is set to minus screw cutter head.
Further, described insulation crust is transparent insulating enclosure.
Further, in described insulation crust, uniformly plastic packaging has fluorescent material.
Relative to prior art, pressing voltage test pencil of the present invention has the advantage that
(1) keep survey electrical contact along draw-in groove stretch out insulation crust time, staff is downwards by starting the hands contact of touched electrode, press connecting rod and be passed down to engaging one rotation torque of lock dog, first spring and the second spring pressurized, pass to engaging one elastic force upwards of lock dog, engaging lock dog is rotated an angle by force action, now engages the convex shoulder that the engaging convex ridge that the lateral wall of lock dog is provided with just can be provided with insulation crust inwall and engages mutually, keeps surveying electrical contact and stretch out insulation crust; Keep survey electrical contact along draw-in groove be collapsible into insulation crust time, need only to staff still further below by starting contact, press connecting rod and can be passed down to rotation torque consistent when engaging lock dog one was pressed with last time again, first spring and the second spring pass to the elastic force upwards that engaging lock dog one is consistent, engaging lock dog by force action can rotate one pressed with last time time consistent angle, the engaging convex ridge now engaging the annular and separation distribution of lock dog just misses the convex shoulder of insulation crust, surveys electrical contact and is collapsible in insulation crust along draw-in groove. The present invention is when user carries, and sharp-pointed survey electrical contact can be collapsible into insulation crust, will not scratch the instrument of carrying, and also is able to save space simultaneously, and the hands contact needing only to press top during use can keep survey electrical contact to stretch out, easy to use. The loophole that insulation crust is provided with contributes to observing neon tube whether starter.
(2) front end surveying electrical contact is set to minus screw cutter head, surveys electrical contact and can be also used as the screwdriver of yi word pattern; Transparent insulation crust contributes to user and observes neon tube whether starter; In insulation crust, uniformly the fluorescent material of plastic packaging contributes to quickly finding in dark conditions the present invention.
