Description

A kind of multifunction test pencil

Technical field

The utility model relates to a kind of electrician's instrument, and concrete is a kind of multifunction test pencil.

Background technology

At present, known test pencil structure is to be in series by test contact, current-limiting resistance, neon tube (or metering circuit), metal spring and hand touched electrode.Test contact is contacted with measured object, staff contact hand touched electrode, when measured object has high voltage relative to the earth, neon tube starter (or pilot lamp is bright), the expression measured object is charged.It only has measuring voltage function, on-off function and 3 kinds of functions of miniature straight screwdriver usually.And the electrician often also needs to use the instruments such as Phillips screwdriver, small flashlight, electrician's knife in routine inspection and simple maintenance debugging work, in the routine work, often comes and goes the working site because leaving behind above certain instrument, makes troubles to work.Especially when high-altitude and operation in narrow space, use multiple types of tools can cause inconvenience to put and carry, sometimes also can be because of the instrument high-altitude generation casualty accident that drops.It is darker to run into working site light, when need using torch dismounting screw, often also needs 2 people's operations, and 1 people is responsible for illumination, and a people is responsible for the dismounting screw, namely takes a lot of work and bothersome, because carrying and using conventional light instrument problem to bring to work and inconvenient.Therefore be necessary to design a kind of multifunction test pencil, satisfy user's demand in operation.

The utility model content

The utility model proposes a kind of multifunction test pencil, make things convenient for the user in dark surrounds, to use, simultaneously also without other instrument of frequent.

The technical solution of the utility model is achieved in that a kind of multifunction test pencil, comprise screwdriver rod, knife bar holder and the handle that links to each other with the knife bar holder, described screwdriver rod is provided with the snap close jack, described knife bar holder is provided with corresponding snap close jack, in the described snap close jack snap close latch is set, in the described knife bar holder spring is set, one end of described spring and screwdriver rod against, described knife bar holder and handle surfaces are equipped with dielectric isolation layer, described handle is provided with display screen, voltage measurement switch and break-make measuring switch, be provided with pilot lamp in the described handle, described display screen, pilot lamp, the voltage measurement switch, be electrically connected between break-make measuring switch and the pilot lamp; Described handle side is provided with the blade support of band blade chute, in the described blade chute blade holder is set, and the blade with fixed orifice is set on the described blade holder.

Further, the setting of in the blade chute, sliding of described blade holder, and the blade holder can skid off in the blade chute.

Further, described knife bar holder front end is provided with the LED bulb, and described handle is provided with battery and bulb switch, is electrically connected between described LED bulb, bulb switch and the battery.

Further, described screwdriver rod one end is the yi word pattern cutter head, and the other end is cross cutter head.

Further, described handle surfaces is provided with hook.

The beneficial effects of the utility model are: multifunction test pencil of the present utility model provides a kind of test pencil that can conveniently use for the user in dark surrounds, torch need to do not used in addition, and driver bit can also be changed as required at any time, if need to cut thing in the operating process, also can be with the blade on the handle, and do not need to change other instrument, the saving of labor is saved trouble again, can hang in the clothing pocket by the side hook obsolete the time, the utility model has solved electrician's Simple compact instrument commonly used and has carried and awkward problem.
