Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is elaborated.
Embodiment: as it is shown in figure 1, a kind of Multi-function electrician test pencil, including including the connected insulated handle of test contact 12, insulated handle 2 is internal is provided with cavity 3, is sequentially filled protected resistance 4, neon tube 5, spring 6 and metal end 7 in cavity 3；It is characterized in that: the end of described neon tube 5 is provided with the limiting plate 9 for snap-springs 6, the internal diameter of this limiting plate 9 matches with spring 6 external diameter；Described limiting plate 9 is arranged at neon tube 5 and the junction of spring 6, and limiting plate 9 is in mating connection with neon tube 5 and spring 6, use such scheme, we are when using test pencil, in mating connection by limiting plate 9 and neon tube 5 and spring 6, make neon tube 5 can be in one all the time with spring 6 and contact state relatively smoothly, effectively prevent the connection skew between neon tube 5 and spring 6, and then affect the accuracy and safety measured.
Metal end 7 is threaded connection with insulated handle 2, when test pencil damages, it is possible to metal end 7 of outwarding winding, and takes test pencil apart, changes and damages parts, thus extends the service life of test pencil.
Neon tube 5 is provided with guide plate 14 with the junction of spring 6；Guide plate 14 is made for conductive material, or guide plate 14 is made for metal material；The shape of guide plate 14 matches with the end of neon tube 5, and the two ends of guide plate 14 are provided with guide pillar 15, and guide pillar 15 is slidably connected on limiting plate 9；Using such scheme so that guide plate 14 increases with the contact area of neon tube 5 and spring 6, the most beneficially neon tube 5 can be in one all the time and contact state relatively smoothly with spring 6, it is ensured that the accuracy of measurement.
The length of limiting plate 9 is at least the 1/2 of spring 6 length, further limit the springing stroke of spring, it is to avoid the test pencil that spring deformation or skew cause produces error.
One end of spring 6 is fixed on metal end 7 so that it is more accurate to test；One end of limiting plate 9 is connected to neon tube 5, and the other end offsets with metal end 7, decreases the contact unstability of neon tube 5 and spring 6.
