Abstract
The utility model discloses a test pencil which comprises a nylon handle, a sleeve and a telescopic rod. The telescopic rod is arranged between the nylon handle and the sleeve; a front end of the sleeve is provided with a metal wafer; an outside of the metal wafer is provided with a rubber sleeve; the metal wafer is fixedly connected with the sleeve; a spring is arranged inside the sleeve; a tail end of the rubber sleeve contacts the spring; a battery, a diode and a screw are arranged inside the nylon handle; and an LED lamp bead is arranged at each of two sides of the tail end of the rubber sleeve, wherein the two sides are close to the metal wafer. The test pencil of the utility model, when in use, uses the rubber sleeve to lean against a switch housing; at the same time, the rubber sleeve contracts inwardly due to effects of the spring, and the metal wafer is exposed, so that the test pencil can be used to test the power; the residues on the metal wager can be effectively removed; if the test pencil is used in places difficult to test the power, the telescopic rod is turned to lengthen the entire test pencil; and if light in the environment is low, the LED lamp beads are used for lighting so that convenience and fastness are realized.
Description
Technical field
The utility model relates to a kind of test pencil.
Background technology
Test pencil is used for daily life to be measured the electric current in the contactor, if electric current is arranged, then the lamp on the test pencil lights, and also can show current values.But traditional test pencil uses and is stained with easily some impurity afterwards, and then cause in use impurity being brought in the supply hub because metal contact piece directly exposes outside, affects measurement result.And traditional test pencil can not be applicable to the darker place of some light and the difficult place of measuring.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of test pencil safe, simple in structure, applied widely that uses.
The utility model is achieved through the following technical solutions: a kind of test pencil, comprise nylon handle, sleeve and expansion link, described expansion link is arranged between nylon handle and the sleeve, described barrel forward end is provided with metal contact piece, described metal contact piece peripheral hardware rubber sleeve, described metal contact piece is fixedly connected with sleeve, be provided with spring in the described sleeve, described rubber sleeve is terminal to contact with spring, described nylon handle inside is provided with battery, diode and screw, and described nylon handle upper end one side is provided with handle.
As preferred technical scheme, described handle adopts plastic material to make, and described sleeve is wrapped with insulation course.
As preferred technical scheme, described rubber sleeve is terminal, be positioned at the metal contact piece both sides respectively is provided with a LED lamp pearl.
As preferred technical scheme, adopt between described expansion link and nylon handle and sleeve to be threaded.
The beneficial effects of the utility model are: test pencil of the present utility model, when needs use, utilize rubber sleeve and switch housing to offset, this moment, rubber sleeve inwardly shrank under the effect of spring, metal contact piece is exposed out, just can be used for surveying electricity and uses, and can effectively remove the residue on the metal contact piece, if be used for the place that some are difficult for measurement, rotatable flexible bar then strengthens the length of whole test pencil, if the environment sight line is darker, then can utilize the illumination of LED lamp pearl, convenient and swift.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of test pencil of the present utility model, comprise nylon handle 1, sleeve 2 and expansion link 3, described expansion link 3 is arranged between nylon handle 1 and the sleeve 2, described sleeve 2 front ends are provided with metal contact piece 7, described metal contact piece 7 peripheral hardware rubber sleeves 9, described metal contact piece 7 is fixedly connected with sleeve 2, be provided with spring 6 in the described sleeve 2, described rubber sleeve 9 ends contact with spring 6, described nylon handle 1 inside is provided with battery, diode 4 and screw, and described nylon handle 1 upper end one side is provided with handle 5.
As preferred embodiment, handle 5 adopts plastic material to make, and described sleeve 2 is wrapped with insulation course.
In the present embodiment, rubber sleeve 9 ends, be positioned at metal contact piece 7 both sides and respectively be provided with a LED lamp pearl 8, light is dark and impact is normal when measuring when measuring, and can utilize side LED lamp pearl 8 to throw light on.
In this practical example, expansion link 3 is threaded with nylon handle 1 and 2 employings of sleeve.
The beneficial effects of the utility model are: test pencil of the present utility model, when needs use, utilize rubber sleeve and switch housing to offset, this moment, rubber sleeve inwardly shrank under the effect of spring, metal contact piece is exposed out, just can be used for surveying electricity and uses, and can effectively remove the residue on the metal contact piece, if be used for the place that some are difficult for measurement, rotatable flexible bar then strengthens the length of whole test pencil, if the environment sight line is darker, then can utilize the illumination of LED lamp pearl, convenient and swift.
The above only be embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
